|Phialocephala species comprise a very small proportion of the fungal biota. This genus is most closely related to Phialophora. 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) sampling. (Spores do not have distinctive morphology and would be categorized as "other colorless" on spore trap samples.) Recorded isolations are from soil, bark, wood (including creosote treated utility poles and submerged balsa wood), and corms of orchids.
