Trichocladium sp.

Mitosporic fungus. Hyphomycetes.

Trichocladium species comprise a small proportion of the fungal biota. This genus is somewhat related to Torula. The only reported human infections are two cases of keratitis (1922, 1965). No information is available regarding toxicity. Allergenicity has not been studied. May be identified on surfaces by tape lifts, and tease mounts from bulk samples. Certain species can be identified in air by culturable (Andersen) samples and certain other species by spore trap samples (spores of some species have distinctive morphology). One species in particular, Trichocladium uniseptatum, is found regularly on environmental surfaces, chiefly from wood. This organism does not grow on general fungal laboratory media and has been reported in times past as an "unknown brown spore type." Recorded isolations of Trichocladium species include soil, wood, tubers of various plants, and pine needles.
