|Sordaria species are common but comprise a small proportion of the fungal biota. This genus is most closely related to other perithecial forming ascomycetes such as Gelasinospora and Melanospora. No information is available regarding health effects or toxicity. Allergenicity has not been studied. May be identified on surfaces by tape lifts, and tease mounts from bulk samples. If Sordaria spores are isolated on culturable (Andersen) sampling, non sporulating mycelia is likely to be the result, at least with primary growth within one week. Sordaria sporulates better on specialized media with a longer incubation period. May be identified on spore trap samples (spores have distinctive morphology but could possibly be confused with other genera). Natural habitat is mainly on dung, but found also on seeds and in soil.
