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: We examined the phylogenetic relatedness of species belonging to Aspergillus section Fumigati using sequence analysis of partial β-tubulin, calmodulin and actin genes including sequences of all known species. ITS sequences were determined from the new species and the species most closely related to them in the β-tubulin tree. The partial β-tubulin gene alignment included 453 characters. Among the polymorphic sites, 102 were found to be phylogenetically informative. The Neighbour-joining tree based on partial β-tubulin genes sequences is shown in Fig. 1. The topology of the tree is the same as one of the 419 maximum parsimony trees constructed by the PAUP programME (length: 465 steps, consistency index: 0.6710, retention index: 0.6467). The calmodulin data set included 549 characters with 85 parsimony informative characters. The Neighbour-joining tree shown in Fig. 2 has the same topology as one of the 9 maximum parsimony trees (tree length: 323, consistency index: 0.7585, retention index: 0.6422). The actin data set included 390 characters with 104 parsimony informative characters. The Neighbour joining tree shown in Fig. 3 has the same topology as one of the 312 maximum parsimony trees (tree length: 397, consistency index: 0.6675, retention index: 0.7130). The ITS data set included 501 characters with 26 parsimony informative characters. The Neighbour joining tree shown in Fig. 4 has the same topology as one of the 57 maximum parsimony trees (tree length: 77, consistency index: 0.7532, retention index: 0.7765).
