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.). Commonly isolated from paper, jute, textiles, adhesives, and gypsum board. Natural habitat is soil and decaying plant material. Also an insect pathogen.
