Emericella sp.

Ascomycetes. Anamorph (asexual state): Aspergillus.

Emericella species are the sexual states of Aspergillus species, notably the Aspergillus nidulans group among others. Emericella is common and is most closely related to Eurotium, another genus with Aspergillus anamorphs. Emericella 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 Emericella 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 Emericella 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. Natural habitat includes soil, seeds, and vegetable matter.
