Trichothecium sp.

Mitosporic fungus. Hyphomycetes. Teleomorph (sexual state): Hypomyces (Tubaki, 1960).

Trichothecium species are common but comprise a small proportion of the fungal biota. This genus is most closely related to Arthrobotrys. There are no reports of infection in humans or animals. No information is available regarding inhalation effects or toxicity. Allergenicity has not been studied. Found frequently growing on indoor environmental surfaces. May be identified on surfaces by tape lifts, tease mounts from bulk samples, and in air by culturable (Andersen) and spore trap samples. (Spores have distinctive morphology.) Natural habitat includes decaying plant material, roots, seeds, nuts, grasses, twigs, water, and soil. It is a parasite on macrofungi, where it can cover with a pink conidial dust. Formerly called Cephalothecium.
