Abstract
Two hundred and forty-four ustilaginomycetous yeast or yeast-like strains were isolated from the soil, skin of animals or humans and plant materials during the past 20 years. Among them, 203 strains represent 39 known species, whereas 41 strains represent several novel species based on the sequence analyses of the rDNA genes [18S rDNA, Internal Transcribed Spacer (ITS) regions, 26S rDNA D1/D2 domain] and three protein genes (RPB1, RPB2, and TEF1). In this study, one new order, one new family, four new genera, twenty new species, and two new combinations were proposed. They are Franziozymales ord. nov., Franziozymaceae fam. nov., Baueromyces gen. nov., Franziozyma gen. nov., Guomyces gen. nov., Yunzhangomyces gen. nov., Baueromyces planticola sp. nov., Franziozyma bambusicola sp. nov., Gjaerumia cyclobalanopsidis sp. nov., Gjaerumia pseudominor sp. nov., Jamesdicksonia aceris sp. nov., Jaminaea lantanae sp. nov., Kalmanozyma hebeiensis sp. nov., Langdonia ligulariae sp. nov., Meira hainanensis sp. nov., Meira pileae sp. nov., Meira plantarum sp. nov., Phragmotaenium parafulvescens sp. nov., Sporisorium cylindricum sp. nov., Sympodiomycopsis europaea sp. nov., Tilletiopsis lunata sp. nov., Tilletiopsis pinicola sp. nov., Yunzhangomyces clavatus sp. nov., Yunzhangomyces cylindricus sp. nov., Yunzhangomyces qinlingensis sp. nov., Yunzhangomyces orchidis sp. nov., Guomyces nicotianae comb. nov., and Yunzhangomces scirpi comb. nov.
