Abstract

is an important genus, with several species associated with infections in humans and animals. In a survey of soil fungal diversity in Yunnan province, PR China, a novel taxon, sp. nov., was identified based on combined morphological and molecular phylogenetic features. Morphologically, this species is characterized by having torulose, septate hyphae and swollen, terminal or intercalary conidiogenous cells arising at acute angles from aerial hyphae. Phylogenetic analysis of the combined sequences of the internal transcribed spacer, the small and large nuclear subunit of the rRNA gene and part of the β-tubulin gene confirmed the phylogenetic position of the new species within the genus .

摘要

是一个重要的属,有几个种与人类和动物的感染有关。在中国云南省土壤真菌多样性调查中,根据结合的形态学和分子系统发育特征,鉴定出一个新的分类单元,。形态上,该种的特点是具有扭曲、有隔膜的菌丝和膨胀的、末端或中间的产孢细胞,从气生菌丝以锐角生出。内部转录间隔区、核糖体 RNA 基因的小和大亚基以及部分β-微管蛋白基因的联合序列的系统发育分析证实了新种在属内的系统发育位置。
