Polyphasic taxonomy of Aspergillus section Fumigati and its teleomorph Neosartorya.

Samson RA, Hong S, Peterson SW, Frisvad JC, Varga J - Stud. Mycol. (2007)

Bottom Line: All newly described and accepted species are illustrated.The section consists of 33 taxa: 10 strictly anamorphic Aspergillus species and 23 Neosartorya species.Four other Neosartorya species described previously were not available for this monograph, and consequently are relegated to the category of doubtful species.

ABSTRACT
The taxonomy of Aspergillus section Fumigati with its teleomorph genus Neosartorya is revised. The species concept is based on phenotypic (morphology and extrolite profiles) and molecular (beta-tubulin and calmodulin gene sequences) characters in a polyphasic approach. Four new taxa are proposed: N. australensis N. ferenczii, N. papuaensis and N. warcupii. All newly described and accepted species are illustrated. The section consists of 33 taxa: 10 strictly anamorphic Aspergillus species and 23 Neosartorya species. Four other Neosartorya species described previously were not available for this monograph, and consequently are relegated to the category of doubtful species.

Mentions: Neosartorya delicata H.Z. Kong (1997) was described based on its ellipsoid or nearly clavate vesicles, and ascospores with conspicuous spines, joining one spine to another by fairly prominent ridges and reticulate ornamentation, the ridges spreading to the equatorial crests. This species has identical ascospore morphology with N. tatenoi (Fig. 36), and both taxa were clustered into a clade in three gene trees (99.6 % in β-tubulin, 98.5 % in calmodulin and 97.3 % in actin gene sequences) (Fig. 5B). Therefore, we consider N. delicata as a synonym of N. tatenoi.
