Abstract

During a survey of soil fungi collected from Yunnan Province, China, two new species of Exophiala, E. yunnanensis and E. yuxiensis, were isolated from the soil of karst rocky desertification (KRD). The DNA sequences of these respective strains, including internal transcribed spacers (ITS), large subunit nuclear ribosomal RNA (LSU rRNA), partial small subunit (SSU) and β-tubulin (tub2) were sequenced and compared with those from species closely-related to Exophiala. Exophiala yunnanensis differs from the phylogenetically closely related E. nagquensis and E. brunnea by its smaller aseptate conidia. Exophiala yuxiensis is phylogenetically related to E. lecanii-corni, E. lavatrina and E. mali, but can be distinguished from them by its larger conidia. Full descriptions, illustrations and phylogenetic positions of E. yunnanensis and E. yuxiensis were provided.
