Eurotium sp.

Ascomycetes. Anamorph (asexual state): Aspergillus.

Eurotium species are the sexual states of Aspergillus species, notably the Aspergillus glaucus group among others. Eurotium is common and is most closely related to Emericella, another genus with Aspergillus anamorphs. Eurotium is likely to be present along with related Aspergilli if growth has been long term and the nutrients of the substrate are conducive for the conversion to sexual phase. Health effects, allergenicity, and toxicity of Eurotium are closely related to the Aspergillus anamorph and, for the most part, have not been studied apart from that primary phase. May be identified on surfaces by tape lifts, tease mounts from bulk samples, and in air on spore trap samples. (Spores have distinctive morphology.) If Eurotium spores are isolated on culturable (Andersen) sampling, the Aspergillus anamorph is likely to be the identifiable result, at least with primary growth within one week. Occurs on substrates low in moisture (xerophilic); very common in stored seeds, grows also on textiles, leather, and materials coated with resins and lacquers, such as furniture.
