Abstract

Asexual and sexual morphs of saprobic bambusicolous fungi were collected from freshwater and terrestrial habitats in Sichuan Province, China. Taxonomic identification of these fungi was carried out on the basis of morphological comparison, culture characteristics, and molecular phylogeny. Multi-gene phylogeny based on combined SSU, ITS, LSU, and sequence data was performed to determine their phylogenetic placement, and the result showed that these fungi belong to Savoryellaceae. Morphologically, four asexual morphs are similar to and , while a sexual morph well-fits to . Three new species, , , and are identified and described. Two new records, and were recovered from the bamboo hosts in terrestrial and freshwater habitats, respectively. In addition, the nomenclatural confusion of and is discussed.

摘要

从中国四川省的淡水和陆地生境中采集了腐生竹生真菌的无性型和有性型。基于形态比较、培养特征和分子系统发育对这些真菌进行了分类鉴定。基于SSU、ITS、LSU组合序列数据进行了多基因系统发育分析以确定它们的系统发育位置，结果表明这些真菌属于萨沃里菌科。在形态上，四个无性型与[具体无性型名称1]和[具体无性型名称2]相似，而一个有性型与[具体有性型名称]相符。鉴定并描述了三个新物种，即[新物种名称1]、[新物种名称2]和[新物种名称3]。分别从陆地和淡水生境的竹子寄主中发现了两个新记录种，即[新记录种名称1]和[新记录种名称2]。此外，还讨论了[物种名称1]和[物种名称2]的命名混乱问题。
