2 Introduction: On the date indicated above, a mold assessment was conducted at the subject property. The assessment strictly applies to the visual area of the home specified by the client defined areas. This Mold Assessment Report only applies to the conditions of the home on the day of the assessment. Many factors (hidden and/or visible) can contribute to mold growth which may or may not be identified in this report. Examples of factors include improper ventilation, high humidity, and uncontrolled moisture problems such as leaks. Mold is a part of the natural environment and is a simple, microscopic organism whose purpose is to break down and decompose. Mold can be found on any material. Mold spores are lightweight and spread by air currents. If spores settle on a suitable surface, they will begin to grow. In order to thrive, mold requires four things: water, organic materials, oxygen, and an optimum temperature (between 40 and 90 degree F). Mold growth is often seen as a discoloration and can grow in several different colors. The most common are white, orange, pink, blue, green, black, or brown. A relative humidity range of 40% to 50% is comfortable for most people without leading to potential moisture problems. Most molds require a surface moisture or humidity level of 70% to 90% to start to grow. CDC recommends keeping humidity levels as low as you can-no higher than 50%. Spores can germinate after as little as 12 hours in some conditions and some grow in 24 to 48 hours. Houses offer an ample food supply - drywall, wood, insulation, and paper. When these materials become damp or wet, settled spores can become growing molds. Molds may colonize in 1 to 12 days depending on the type of mold. Due to the volatile properties of mold conditions and how quickly a given condition can change, mold remediation should be commenced within 10 days of this assessment. This assessment is for the client only and is not transferable. The rest of this page was intentionally left blank.

3 Observations: The subject property was being assessed due to concerns for possible mold contamination in the attic, which was discovered during a home inspection. This report is being provided to the potential buyer. The following health concerns were described: None Upon entry of the attic area it was observed that the space was clear with a low head area (Figure 2). A strong mildew odor could be noticed. Visual confirmation of mold was made on multiple sheathing areas (Figure 3-5). The contamination was light, but widespread and difficult to photograph. Indoor relative humidity was observed using a Psychrometer (Figure 6). The relative humidity was recorded as 68% and the temperature was recorded as 80F. Testing for scientific confirmation by accredited lab service was conducted as follows: 1) Attic sheathing, Results are positive for heavy growth of Cladosporium and light growth of Basidiomycetes. The cause of the mold contamination could not be clearly identified however, most possible cause is due to lack of ventilation and undersized soffit area. Standard building practices typically require one square foot of vent area for 150 square feet of attic space distributed evenly between ridge and soffits, but some attics may require more. The proper flow of air should include two components one which allows warm air to exit at the highest point and one which allows cooler air to enter at the lowest point, this creates a draft to flow through the attic. As warm air rises cool air enters. Undersized soffits can lead to lack of attic ventilation, which can lead to a moldy attic. It was observed that most ridge vents were crushed and possibly chewed by attic rodents and areas were stuffed with insulation. It was also observed that bathroom vents were vented into the attic space. As warm moist air exits the bathroom vent fan, cooler air cools and condensates on roof substrates eventually creating optimal conditions which are conducive to mold growth.

4 Problems Identified: Lack of Ventilation Excessive Humidity Leak Other Water Purity: Clean Sanitary Grey Non-Sanitary Black Raw Sewage None Possible Hazardous Asbestos Materials Exist: Lead Unknown Other Recommendations: This Assessment Report is for the attic area ONLY. Size of remediation is >100 SF. Remediation means and methods per Mold Remediation Project Overview, Medium to Large Remediation, as described below, shall be used. All mold stained building materials shall be removed and replaced and/or cleaned by means of HEPA vacuum removal, sanitization and treated with fungicidal inhibitor and encapsulate as necessary, whichever is the most cost effective manner. Treated materials shall include, but is not limited to, roof sheathing, gable end walls, insulation, and roof truss. Relative humidity shall be maintained below 50%. At the time of this inspection the cause of the mold could not be clearly identified, however, it is most likely due to the observations listed above. It is recommended that a qualified contractor be contacted to check, verify and determine that attic ventilation is adequate. Check soffit areas for proper ventilation and remove obstructions, check ridge vent areas and verify all bathroom vents and ducts are insulated and vented to exterior. It is highly recommended that bathroom fans be vented through an elevated gable wall and not into soffit areas. NOTE: A general contractor may be required to perform certain parts of this work. Air testing is recommended for verification of cleanup. Approximate Size of Cleanup: 500+/- SF Estimated Cost of Mold Remediation: $2,500 - $3,500 Approximate Duration of Cleanup: 3 Days SAMPLE DOCUMENT The rest of this page was intentionally left blank.

9 Client Information: Name: John Doe Address: 90 Fake Road, Malta, NY Phone: Post-Remediation Clearance Assessment: NYS Mold Assessor License #00742 Date 8/31/17 Satisfactory Partial Unsatisfactory The attic was re-inspected for clearance on 8/31/17 and was cleared. All visual mold and mold staining was remediated and encapsulate was in place. Partial clearance results when clearance requirements and/or all recommendations are not met, but mold staining is verified removed. Containment was removed prior to clearance, therefore, air testing was completed for verification of cleanup. The air sample results were compared to the Indoor Air Quality Report performed on 7/19/17 and attic swab collected on 8/24/17. Indoor Air Quality Report was satisfactory with no elevations in indoor spores. Basidiomycetes were scientifically verified to be light growth and Cladosporium was scientifically verified to be heavy growth on attic sheathing tested on 8/24/17. The two mold types corresponded with the Indoor Air Quality Report, but were not elevated. In comparison to the clearance air samples collected on 8/31/17, it can be noted that Cladosporium is slightly elevated in comparison to Indoor Air Quality Report data. Although, slightly elevated, clearance air results are acceptable. It cannot be confirmed or denied if the slight increase resulted from the attic remediation. It is recommended that general interior spaces be thoroughly cleaned including steam cleaning of carpets with antimicrobial/antifungal treatment and that interior surfaces be wiped clean with a sanitizing spray. Additionally, follow up air sampling can be considered to verify all elevated spores have returned to normal levels. These additional precautions are not mandatory. Additional Post-Remediation Clearance Assessment: Date Satisfactory Partial Unsatisfactory This section will be updated, once the remediation is complete and Bald Eagle Inspection Services, LLC returns to perform the post remediation clearance assessment.

10 The following information is unofficial and opinionative in nature and has been compiled from outside resources as a guide to help understand mold concentrations. This guide shall not be considered a final conclusion of mold remediation requirements. The Most Relevant Mold Species: Penicillium/Aspergillus - The most common mold species to show up in Indoor Air Samples. Most of the hundreds of sub-species are allergenic with only a few that are toxic. This group of species will grow with only the humidity in the air as its water source. An A/C failure will allow this mold to start growing on walls, furniture and clothing. Cladosporium - The most common mold species and is considered to be an allergenic. Curvularia This is another common allergenic mold. Chaetomium - This is a common water marker that usually indicates wet paper and/or drywall. Stachybotrys An excellent water marker and the most common toxic mold species. Stachybotrys Chartarum is the sub-species that s the subject of all the 60 Minutes type news programs and all of the internet hype. Not all sub-species are toxic. These species need a direct water source to grow. This includes a window, roof or plumbing leak. Memnoniella A sister mold to Stachybotrys. The two species will grow together. It is also considered toxic. Mold Spore Level Guide : For years there have been debates over how to set a standard for mold spore levels in homes. Because mold spore species and levels differ from state to state, no one has been able to agree. So a comparison to an outdoor air sample has been the rule of thumb. This is because you are letting mold spores into a home every time you open a door or window. It is not a perfect method and can lead to false positives. The following mold spore ranges are my opinion and are based on thousands of samples performed by me in the Collier, Lee & Charlotte county area during a Mold Inspection. For this guide use the spore/m3 number and not the raw count for each species when you interpret an Air Sample Report from a Lab. There are exceptions at every level. False positives can be caused by a number of different issues. Normal life examples are dust and dirt on fan blades or other surfaces of the home, something in a garbage can or household pets that have been playing outside. When a general home or termite inspection is performed at the same time as the mold inspection it can inadvertently raise the spore counts. This can happen if an interior attic access is opened or the A/C filter is removed from the return before the air sample is performed.

Background debris or Description Light General impression Mold growth and Growth of a basidiomycete * See Mold/Fungal Growth Details table on the last page. ** See Miscellaneous Spores table on the last page. Some comments may refer to the following: Most surfaces collect a mix of spores which are normally present in the outdoor environment. At times it is possible to note a skewing of the distribution of spore types, and also to note "marker" genera which may indicate indoor mold growth. Marker genera are those spore types which are present normally in very small numbers, but which multiply indoors when conditions are favorable for growth. Background debris is an indication of the amounts of non biological particulate matter present. This background amorphous material is graded and described as scant, light, moderate, heavy, or very heavy. (Very heavy background debris may obscure visibility.) Fungal types listed without a growth rating or data entry were not detected during the course of the analysis for the respective sample. Interpretation is left to the company and/or persons who conducted the field work. A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x". The limit of detection is < 1+ when mold growth is detected. EMLab ID: , Page 2 of 3

14 Client: Bald Eagle Inspection Services, LLC C/O: Mr. Jason Federico Re: John Doe - 90 Fake Road, Malta; NY Attic Mold/Fungal Growth Rating Details Growth Rating < 1+ (Very Light Growth) EMLab P&K Date of Sampling: Date of Receipt: Date of Report: Quantities of molds indicating growth are listed in the MOLD/FUNGAL GROWTH section. Judgement is used in determining the amount of growth present in the sample. For example, if only one portion of the sample has evidence of heavy growth, then it will receive a rating of heavy growth even though, strictly speaking, on a percentage basis of the entire sample, the amount of growth is low. Swab/Tape/Dust/Wipe sample Evidence of very light growth observed on the sample as indicated by spores of one type seen with underlying mycelial and/or with their sporulating structures found in less than 10% of the microscopic fields examined. Bulk Sample Areas of very light growth detected by the presence of spores of one type seen with underlying mycelial and/ or with their sporulating structures in the bulk sample. 1+ (Light Growth) 2+ (Moderate Growth) 3+ (Heavy Growth) 4+ (Very Heavy Growth) Evidence of light growth observed on the sample as indicated by spores of one type seen with underlying mycelial and/or with their sporulating structures found in 10 to 25% of the microscopic fields examined. Evidence of moderate growth observed on the sample as indicated by spores of one type seen with underlying mycelial and/or with their sporulating structures found in 26 to 50% of the microscopic fields examined. Evidence of heavy growth observed on the sample as indicated by spores of one type seen with underlying mycelial and/or with their sporulating structures found in 51 to 75% of the microscopic fields examined. Evidence of very heavy growth observed on the sample as indicated by spores of one type seen with underlying mycelial and/or with their sporulating structures found to be nearly confluent in the majority of the microscopic fields examined. Areas of light growth detected by the presence of spores of one type seen with underlying mycelial and/ or with their sporulating structures in the bulk sample. Areas of moderate growth detected by the presence of spores of one type seen with underlying mycelial and/ or with their sporulating structures in the bulk sample. Areas of heavy growth detected by the presence of spores of one type seen with underlying mycelial and/ or with their sporulating structures in the bulk sample. Areas of very heavy growth detected by the presence of spores of one type seen with underlying mycelial and/ or with their sporulating structures in the bulk sample. Miscellaneous Spores Slides/specimens are examined for the presence of mold spores and pollen, noting the quantities and distribution of spore types found. A designation of 'normal trapping' is made when a mix of spore types is present with the same general distribution as is usually found outdoors. In other words, the biological component of the sample surface is like that found everywhere. Types of spores present would include basidiospores (mushroom spores), myxomycetes (slime molds), plant pathogens such as ascospores, rusts and smuts, and a mix of saprophytic genera with no particular spore type predominating. Many of these spore types would not be found growing indoors on building materials since many plant pathogens require living plants for growth, and mushrooms require compost, leaf duff of various types, or associations with roots of certain trees, etc. Due to these factors, when a mix of spores seen include these types as well as pollen, the rational source is the outside air, rather than indoor mold growth. The numbers of miscellaneous spores seen are graded and described as shown below as none, very few, few, variety, and wide variety. None Very Few Few Variety Wide Variety No spores detected Very few spores A few spores detected detected Many spores containing a variety of different genera detected Many spores containing a wide variety of different genera detected EMLab ID: , Page 3 of 3

They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and may be undercounted. Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and may be higher than reported. It is important to account for samples volumes when evaluating dust levels. The analytical sensitivity is the spores/m^3 divided by the raw count, expressed in spores/m^3. The limit of detection is the analytical sensitivity (in spores/m^3) multiplied by the sample volume (in liters) divided by 1000 liters. For more information regarding analytical sensitivity, please contact QA by calling the laboratory. A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".

The last column represents the frequency of occurrence. The low, medium, and high values represent the 2.5, 50, and 97.5 percentile values of the spore type when it is detected. For example, if the frequency of occurrence is 63% and the low value is 53, it would mean that the given spore type is detected 63% of the time and, when detected, 2.5% of the time it is present in levels above the detection limit and below 53 spores/m3. These values are updated periodically, and if enough data is not available to make a statistically meaningful assessment, it is indicated with a dash. The Typical Outdoor Data by Location represents the typical outdoor spore levels for the region indicated for the entire year. As with the Typical Outdoor Data by Date, the four columns represent the frequency of occurrence and the typical low, medium, and high concentration values for the spore type indicated. These values are updated periodically, and if enough data is not available to make a statistically meaningful assessment, it is indicated with a dash. Total Spores/m3 has been rounded to two significant figures to reflect analytical precision. * The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces rapidly and are very easily dispersed. Other genera are usually present in lesser numbers. ** These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens. However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of a single morphological type of basidiospore on an inside sample should be considered significant.

21 Client: Bald Eagle Inspection Services, LLC C/O: Mr. Jason Federico Re: John Doe- 90 Fake Road, Malta; Attic Clearance MoldSCORE : Spore Trap Report EMLab P&K Date of Sampling: Date of Receipt: Date of Report: * The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces rapidly and are very easily dispersed. Other genera are usually present in lesser numbers. ** These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens. However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of a single morphological type of basidiospore on an inside sample should be considered significant. The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing characteristics. They cannot be differentiated by non-viable sampling methods. Rated on a scale from 100 to 300. A rating less than 150 is low and indicates a low probability of spores originating inside. A rating greater than 250 is high and indicates a high probability that the spores originated from inside, presumably from indoor mold growth. A rating between 150 and 250 indicates a moderate likelihood of indoor fungal growth. MoldSCORE is NOT intended for wall cavity samples. It is intended for ambient air samples in residences. Using the analysis on other samples (like wall cavity samples) will lead to misleading results. EMLab ID: , Page 2 of 2

Drechslera, Bipolaris, and Exserohilum group Epicoccum sp. Memnoniella sp. Myxomycetes Penicillium sp. Pithomyces sp. Rusts Smuts Stachybotrys sp. Ulocladium sp. EMLab ID: , Page 1 of 23

25 Alternaria sp. Mitosporic fungus. Hyphomycetes. Anamorphic Pleosporaceae. Distribution Ubiquitous; cosmopolitan. Approx species. EMLab P&K Where Found Soil, dead organic debris, on food stuffs and textiles. Plant pathogen, most commonly on weakened plants. Mode of Dissemination Dry spore. Wind. Allergen Commonly recognized. Type I allergies (hay fever, asthma). Type III hypersensitivity pneumonitis: Woodworker's lung, Apple store hypersensitivity. May cross react with Ulocladium, Stemphylium, Phoma, others. Potential Opportunist of Pathogen Nasal lesions, subcutaneous lesions, nail infections; the majority of infections reported from persons with underlying disease or in those taking immunosuppressive drugs. Most species of Alternaria do not grow at 37oC. Potential Toxin Production A. alternata produces the antifungal alternariol. Other metabolites include AME (alternariol monomethylether), tenuazonic acid, and altertoxins (mutagenic). Growth Indoors On a variety of substrates. Aw= (minimum for various species) Industrial Uses Biocontrol of weeds and other plants. Other Comments One of the most common fungi worldwide. Characteristics: Growth/Culture Grows well on general fungal media. Colonies are dark olive green to brown, floccose to velvety (heavily sporulating). Colonies become pleomorphic over time, and lose the ability to sporulate with subsequent transfer. Notes on Spore Trap Recognition Distinctive. Young spores or spore fragments may be confused with Ulocladium, Pithomyces, Stemphylium, or Epicoccum. (Some Alternaria species cannot be separated from Ulocladium.) Notes on Tape Lift Recognition Distinctive. Readily identifiable on tape lift samples. EMLab ID: , Page 2 of 23

26 EMLab P&K Ascospores Spore category. Produced by morels, truffles, cup fungi, ergot and many micro-fungi. Distribution Ubiquitous. More than 3,000 genera. Where Found Saprophytes and plant pathogens. Found everywhere in nature. Mode of Dissemination Spores are predominantly forcibly discharged during periods of high humidity or rain. Allergen Highly variable, dependent on genus and species. Poorly studied. Potential Opportunist of Pathogen Dependent on genus and species, but the vast majority do not cause disease. Potential Toxin Production Very many, dependent on genus and species. Growth Indoors The cellulolytic ascomycetes Chaetomium and Ascotricha are frequently found growing indoors on damp substrates. Industrial Uses Dependent on genus and species. Other Comments Some of the common asexual fungi such as Penicillium and Aspergillus produce sexual forms under certain conditions; these are classified in the ascomycete group and given distinct names. For example, the most common sexual forms of Penicillium are Talaromyces and Eupenicillium; the most common sexual forms of Aspergillus are Eurotium and Emericella. Characteristics: Growth/Culture While some ascomycetes sporulate in culture (Chaetomium, Pleospora), many are parasitic plant pathogens, and sporulate (grow) only on living host plants. Notes on Spore Trap Recognition Many ascospores are distinctive. Many others will be classified as "other colorless." In general, ascospores are recognizable by the fact that they have no attachment points, and are sometimes enclosed in gelatinous sheaths or within a sac. Notes on Tape Lift Recognition Many ascomycetes are distinctive, and readily identified on tape samples, especially if fruiting bodies are present. EMLab ID: , Page 3 of 23

Water requirements range widely (dependent on species). Aw= (minimum for various species). Industrial Uses Many, including practical applications in food production. For example, A. oryzae is used to ferment soybeans to soy sauce. A. terreus produces mevinolin which is able to reduce blood cholesterol; A. niger is used in the bread and beer making industries (enzyme production) and also is able to decompose plastic. A. niger and A. ochraceus are used in cortisone production. Other Comments Aspergillus is one of the most common fungal genera, worldwide, and Aspergillus fumigatus is one of the most common species found. EMLab ID: , Page 4 of 23

28 Aspergillus sp. (continued) EMLab P&K Characteristics: Growth/Culture Aspergillus species grow well on general fungal media. Some xerophilic species prefer dryer conditions. Notes on Spore Trap Recognition Free spores are indistinguishable from Penicillium, and other genera with small round to oval colorless spores. Penicillium/Aspergillus spores may have remnants of cell wall connections. Notes on Tape Lift Recognition If sporulating structures are present, Aspergillus is readily identifiable on tape samples. Old growth or samples with very large numbers of spores may not contain structures necessary for identification and are reported as "spores typical of Penicillium/Aspergillus." EMLab ID: , Page 5 of 23

29 EMLab P&K Basidiospores Spore category. Produced by mushrooms, puffballs, shelf fungi, rusts, smuts, and many other fungi. Distribution Ubiquitous; cosmopolitan. Approx. 1,200 genera. Where Found Saprophytes and plant pathogens. Gardens, forests, woodlands. Mode of Dissemination Wind; spore release (active mechanism) during periods of high humidity or rain. Allergen Probably common. Type I allergies (hay fever, asthma). Type III hypersensitivity pneumonitis: Lycoperdonosis (puffball spores), Mushroom culture hypersensitivity. Potential Opportunist of Pathogen Asexual forms may cause rare opportunistic infections. The yeast Cryptococcus neoformans is a basidiomycete. Potential Toxin Production Mushroom toxicosis (poisoning) is usually a result of ingestion of the following toxins: amanitins, monomethylhydrazine, muscarine, ibotenic acid, psilocybin. Growth Indoors Serpula lacrimans, the agent of "dry rot," and other fungi causing white and brown wood rot, grow and destroy the structural wood of buildings. Poria incrassata causes a particularly destructive dry rot in buildings. Industrial Uses Many mushrooms are edible, and very important in the food industries. Other Comments Occasionally, a benign, non-wood rotting mushroom will fruit inside a building, growing in some unique ecological niche if enough moisture is present. If mushrooms are found growing indoors we ask clients to submit the entire mushroom for identification. Characteristics: Growth/Culture Most Basidiomycetes will not fruit on laboratory media. Many will form arthrospores or sterile mycelia on laboratory media. Notes on Spore Trap Recognition Most basidiospores have a distinctive asymmetrical attachment point. Many basidiomycetes have recognizable spores. Serpula, the agent of dry rot, with tan-orange basidiospores, can sometimes be identified on spore trap slides. EMLab ID: , Page 6 of 23

30 Basidiospores (continued) EMLab P&K Notes on Tape Lift Recognition Except for the occasional finding of Serpula (above), basidiospores are rarely found on tape lifts, except as a part of normal influx of outdoor spores. EMLab ID: , Page 7 of 23

31 Chaetomium sp. Ascomycete. Distribution Ubiquitous; cosmopolitan. Approx. 81 species. EMLab P&K Where Found Soil, seeds, cellulose substrates, dung, woody and straw materials. Mode of Dissemination Spores are formed inside fruiting bodies. Spores are forced out an opening and spread by wind, insects, water splash. Allergen Not well studied. Type I allergies (hay fever, asthma). Potential Opportunist of Pathogen Uncommon agent of onychomycosis (nail infection). Potential Toxin Production Chaetomin. Chaetomium globosum produces chaetoglobosins. Sterigmatocystin is produced by rare species. Other compounds produced (which may not be mycotoxins in the strict sense) include a variety of mutagens. Growth Indoors Widespread, cellulolytic, very commonly found on damp sheetrock paper. Industrial Uses Used in textile testing and the production of cellulase. Other Comments None. Characteristics: Growth/Culture Grows and sporulates on general fungal media, may need 8-20 days for fruiting body production and sporulation. Notes on Spore Trap Recognition Distinctive. Chaetomium globosum has small brown "lemon" or "football-shaped" ascospores. Notes on Tape Lift Recognition Distinctive and readily identifiable on tape lifts. EMLab ID: , Page 8 of 23

32 EMLab P&K Cladosporium sp. Mitosporic fungus. Hyphomycetes. Teleomorphs (sexual state): Mycosphaerella, Venturia (Ascomycetes). Distribution Ubiquitous; cosmopolitan. Approx species. One of the most common genera, worldwide. Where Found Soil of many different types, plant litter, plant pathogen, leaf surfaces, old or decayed plants. Mode of Dissemination Dry spore (formed in very fragile chains, easily dispersed). Wind. Allergen Common and important allergen. Type I allergies (hay fever, asthma). Type III hypersensitivity pneumonitis: Hot tub lung, Moldy wall hypersensitivity. Potential Opportunist of Pathogen Generally, non-pathogenic. One species, Cladosporium carrionii, is an agent of chromoblastomycosis in subtropical and tropical regions (grows at 35-37oC). Potential Toxin Production Cladosporin, emodin. (Neither are highly toxic.) Growth Indoors Widespread, on many substrates, including textiles, wood, moist window sills. Grows at 0oC, and so is associated with refrigerated foods. Aw= (minimum for various species). Industrial Uses C. herbarum produces enzymes which are used in the transformation of steroid intermediates such as pregnenolone and progesterone, biologically important hormones used in the industrial production of oral contraceptives. Other Comments G.S. dehoog & J. Guarro have placed species associated with human infection in a new genus Cladophialophora, i.e. Cladophialophora carrionii, C. bantiana. Older medical texts refer to this fungus by its former name Hormodendron species. Characteristics: Growth/Culture Grows on all general fungal media. Some species sporulate better than others, and some may need cycles of light in order to produce spores. Notes on Spore Trap Recognition Distinctive, with wide variation in size and shape. Spores with dark attachment scars and some olive to brown pigmentation are identified as Cladosporium. EMLab ID: , Page 9 of 23
