Aspergillus osmophilus sp. nov., and a new teleomorph for A. proliferans

A new species of Aspergillus and a new teleomorph for A. proliferans, both isolated from cereals in Iran, are described using morphological and molecular data. A combined sequence dataset of the ITS region, partial β-tubulin and partial calmodulin genes resolved the relationships of members of section Aspergillus largely in concordance with morphological traits of ascospores. Aspergillus osmophilus sp. nov. is differentiated from the closest species, A. xerophilus by possessing larger ascospores, conidia and associated fruiting bodies. Both species are strongly xerophilic and possess ascospores with lobate-reticulate convex surfaces. The newly discovered teleomorph for A. proliferans is characterized by delicately roughened ascospores with a shallow or distinct furrow and finely roughened to irregular equatorial crests.     

A new species ofNeosartorya from Taiwan soil

The species is characterized by its restricted growth on Czapek agar, white ascomata, nearly globose ascospores with ribbed surface ornamentation of several linear ridges, and a limited development of conidia on common media. A key to all accepted species of the genus is provided.     

New taxa of Neosartorya and Aspergillus in Aspergillus section Fumigati

Three new species of Neosartorya and one new Aspergillus of section Fumigati are proposed using a polyphasic approach based on morphology, extrolite production and partial β-tubulin, calmodulin, and actin gene sequences. The phylogenetic analyses using the three genes clearly show that the taxa grouped separately from the known species and confirmed the phenotypic differences. Neosartorya denticulata is characterized by its unique denticulate ascospores with a prominent equatorial furrow; N. assulata by well developed flaps on the convex surface of the ascospores which in addition have two distinct equatorial crests and N. galapagensis by a funiculose colony morphology, short and narrow conidiophores and ascospores with two wide equatorial crests with a microtuberculate convex surface. Aspergillus turcosus can be distinguished by velvety, gray turquoise colonies and short, loosely columnar conidial heads. The four new taxa also have unique extrolite profiles, which contain the mycotoxins gliotoxin and viriditoxin in N. denticulate; apolar compounds provisionally named NEPS in N. assulata and gregatins in N. galapagensis. A. turcosus produced kotanins. N. denticulata sp. nov., N. assulata sp. nov., N. galapagensis sp. nov., and A. turcosus sp. nov. are described and illustrated.
