Neosartorya sp.

Ascomycetes. Anamorph (asexual state): Aspergillus.
Neosartorya species are the sexual states of Aspergillus species, notably the Aspergillus fumigatus group among others. Neosartorya is common and is most closely related to Emericella, another genus with Aspergillus anamorphs. Neosartorya 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. Reports of illness include pulmonary infection, endocarditis, and osteomylelitis. Health effects (for the most part), allergenicity, and toxicity of Neosartorya are closely related to the Aspergillus anamorph and have rarely been studied apart from that primary phase. May be identified on surfaces by tape lifts, and tease mounts from bulk samples, especially if the Aspergillus anamorph is present. If Neosartorya 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. Spores have somewhat distinctive morphology but would most probably be called "ascospores" on spore trap samples. Natural habitat is soil.
