|Zygosporium species comprise a small proportion of the fungal biota. 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. (Spores do not have distinctive morphology and would be categorized as "other colorless" on spore trap samples.) Our laboratory sees this organism from time to time growing on damp indoor walls. Natural habitat is primarily dead leaves (many plants), with occasional isolations from soil.
