摘要：
Phylogenetic analysis of concatenated nuclear gene sequences for large and small subunit rRNA, translation elongation factor 1-, and the two large subunits of RNA polymerase II (RPB1, RPB2) demonstrated that species assigned to the yeast genus Ascoidea represent two separate and distantly related clades, that is, Ascoidea (A.asiatica, NRRL Y-17632, CBS 377.68; A.rubescens, NRRL Y-17699, CBS 116.35, type species; A.tarda sp. nov., NRRL Y-2393, CBS 12609, type strain), which is near the genus Saccharomycopsis, and Alloascoidea gen. nov. (Al.africana comb. nov., NRRL Y-6762-3, CBS 12606, Al.hylecoeti comb. nov., NRRL Y-17634, CBS 355.80, type species), which is near Nadsonia and related genera. From these analyses and from comparison of herbarium specimens, it appears that type strains of A.asiatica and Al.africana had been reversed. Sequence analysis further showed that Schizoblastosporion starkeyi-henricii is a sister species of Nadsonia fulvescens and it is proposed for transfer to Nadsonia.
