|Thysanophora species comprise a very small proportion of the fungal biota. This genus is related to Penicillium, Phialocephala, and Gliocladium. No information is available regarding health effects or toxicity. Allergenicity has not been studied. May be identified on surfaces by tape lifts, tease mounts from bulk samples, and in air by culturable (Andersen) samples. May be identified on spore trap samples if the presence of this genus has already been demonstrated (for example, on tape lifts). (Spores do not have distinctive morphology and would be categorized as "other colorless" on spore trap samples.) Recorded isolations include soil, leaves of Tsuga, and decaying leaves.
