摘要

摘要/ Abstract摘要:为了进一步明确黑藓科水生藓属(Aquanectria)、Cosmospora、Fusicolla等相关分类群之间的系统发育关系，本文基于中国淡水生境真菌标本的ITS、LSU和β-微管蛋白DNA序列，对其进行了详细的形态特征分析和枝系分析。本文描述了一个新属，cosmsporella，以容纳C. olivacea作为其模式种。基于形态上的相似性和系统发育上的支持，将暗色宇宙孢子虫归入宇宙孢子虫。jacinthicolor Aquanectria jacinthicolor是一种淡水木本植物分类群，其特征是其桔黄色的子囊孢子和椭圆形的子囊孢子，具有宽的伞状孢子。该种与其他两种已知的水蚤属有亲缘关系，可根据子囊孢子形态加以区分。本文首次报道了水花Fusicolla aquaeductuum有性形态的标本。

Novel Taxa within Nectriaceae: Cosmosporella gen. nov. and Aquanectria sp. nov. from Freshwater Habitats in China

Abstract To clarify phylogenetic relationships among Aquanectria, Cosmospora, Fusicolla and other related taxa in Nectriaceae, we examined detailed morphological characters and performed cladistic analyses of a concatenated dataset based on the ITS, LSU and β-tubulin DNA sequences of fungal specimens collected from freshwater habitats in China. A new genus, Cosmosporella, is described to accommodate C. olivacea as its type species. Cosmospora obscura is transferred to Cosmosporella based on morphological similarities and phylogenetic support. Aquanectria jacinthicolor, a freshwater lignicolous taxon, characterized by its orange ascomata and ellipsoid ascospores with broad paraphyses is a newly described freshwater species. This species has affinities with other two known species of Aquanectria and can be distinguished based on ascospore morphology. A specimen with sexual morph of Fusicolla aquaeductuum is reported for the first time.

期刊介绍： Cryptogamie is divided into three sections, each published as an individual publication: Cryptogamie, Bryologie, Cryptogamie, Algologie and Cryptogamie, Mycologie. Cryptogamie is a French journal of international scope publishing in several European languages. It accepts original papers and review articles on the systematics, biology and ecology of all cryptogams (algae; bryophytes; fungi and lichens, respectively).
