|Gliomastix species comprise a small proportion of the fungal biota. This genus is most closely related to Acremonium and the monophialidic species of Paecilomyces. 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 have somewhat distinctive morphology but may be confused with other genera. The grey black pigment of the spores is very close to the pigment of Stachybotrys.) Natural habitat includes plant litter, wood, soil and cellulosic materials.
