摘要

从四川省沉水腐朽木材中分离到一株盘基菌科真菌。综合ITS、LSU、SSU和tef1序列数据显示，该物种代表了一个新属，在这里被描述为新趾孢子虫。新趾孢子菌不同于盘基菌科的其他属，基于透明和全变细胞的基底连接分生孢子的细胞，圆锥形且较小，分生孢子排数较少（1-4）。此外，系统发育分析和形态学比较表明，新近引入的Paractyocheirospora属与Digitodesmium属同源。基于这些结果，Paradicytocheirospora被简化为旧属名Digitodesmium下的同义词。

Neodigitodesmium, a novel genus of family Dictyosporiaceae from Sichuan Province, China

A fungus within the family Dictyosporiaceae was isolated from submerged-decaying wood in Sichuan Province, China. Combined ITS, LSU, SSU and tef1 sequence data showed that the species represented a new genus and is described here as Neodigitodesmium cheirosporum gen. et sp. nov. Neodigitodesmium distinct from other genera in the family Dictyosporiaceae based on a hyaline and holoblastic basal connecting conidiogenous cell, conical shaped and smaller with fewer rows (1–4) of conidia. In addition, phylogenetic analysis and morphological comparison showed that the recently introduced genus Paradictyocheirospora is congeneric with Digitodesmium. Based on these results, Paradictyocheirospora is reduced to synonymy under the older generic name Digitodesmium.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
