|Syncephalastrum racemosum (monotypic) is common but comprises a small proportion of the fungal biota. This organism is widely regarded as being nonpathogenic to humans, with only a single case of a cutaneous infection reported (1980). No information is available regarding 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 dung and soil, primarily in tropical and subtropical areas.
