Trichosporon spp.

Trichosporon species are yeast-like fungi that may be isolated from soil, water, vegetables, mammals, and birds. They can also be isolated from the mouth, skin, and nails of humans. They are generally associated with water intrusion in the indoor environment.

Trichothecium spp.

Trichothecium species are fungi that are pathogenic to plants.

Tritirachium spp.

Tritirachium species are fungi that are widespread in decaying vegetation and in the soil. They are insect pathogens.


Ulocladium spp.

Ulocladium species are cosmopolitan dematiaceous (pigmented) fungi commonly found in the soil and on decaying herbaceous plants, paper, textiles, and wood. Although Ulocladium species are common contaminants, their presence indoors may indicate moisture intrusion as they grow optimally in high substrates with high water content.

Unidentifiable dematiaceous fungus

These fungi are darkly pigmented (dematiaceous) and produce conidia (spores) that are not readily identifiable.

Unidentifiable dematiaceous or hyaline conidia

When unidentifiable dematiaceous or hyaline conidia are noted on a direct microscopic examination, it indicates that no particular mold can be identified. Only the fungal conidia are present with no or little additional characteristics to fully identify and categorize them. These conidia may represent such yeast-like fungi as Aureobasidium, Hormonema, Sporidiobolus, Acremonium species, basidiomycetes (basidiospores), and Ascomycetes (ascospores).

Unidentifiable hyaline fungus

These fungi are lightly pigmented (hyaline) and produce conidia (spores) that are not readily identifiable.

Unidentifiable yeast

Unable to obtain an identification by MALDI-TOF mass spectrometry; classification as a yeast is based on morphology only. This is not a definitive identification.

Unidentifiable yeast Type 1

Unable to obtain an identification by MALDI-TOF mass spectrometry; classification as a yeast is based on morphology only. This is not a definitive identification.

Unidentifiable yeast Type 2

Unable to obtain an identification by MALDI-TOF mass spectrometry; classification as a yeast is based on morphology only. This is not a definitive identification.

Unidentifiable zygomycete

Fungi belonging to the class Zygomycetes have a wide geographic distribution and include genera such as Rhizopus, Mucor, and Rhizomucor . They are thermotolerant and can use a variety of substrates as nutrient sources. They can be isolated in large numbers from soil or decomposing organic material. They have also been found in carpet and mattress dust, hay, flour, and potted plants. Their spores can often be found in the outdoor air.

Ustilago spp.

Ustilago species are yeast-like fungi known as smuts which are major plant pathogens.


Verticillium spp.

Verticillium species are fungi which are widely distributed on decaying vegetation and in soil. Some species are parasitic on other fungi, arthropods, and plants.

Vishniacozyma spp.

Vishniacozyma species are a type of basidiomycete yeast isolated from plants, sediments, and soil.

Volutella spp.

Volutella species are a type of fungus which cause a common leaf blight on plants.


Xylaria heliscus

Xylaria species are fungi that grow as finger-like or antler-like projections on dead, rotting wood.


Zasmidium aporosae

Zasmidium species are a type of ascomycete fungi that can be found on plants.
