青海柴达木盆地土壤中的暗色丝孢真菌Ⅰ(英文)

Notes on soil dematiaceous hyphomycetes from the Qaidam Basin,Qinghai Province,ChinaⅠ

从青海省柴达木盆地的不同生态类型地区,采集土样24份,从中分离获得暗色丝孢真菌分离物63个,经鉴定分属于14属中的25种。其中柴达木单格孢Monodictys qaidamensis和多变葡萄穂霉Stachybotrys variabilis为新种,其余为中国已报道种。文中对新种进行了拉丁文描述和图示,对23个国内已知种亦作了分布、生境、产地和海拔高度的引证。所有研究过的标本(干制培养物)与活菌种均保存在山东农业大学植物病理学标本室(HSAUP)。

Sixty-three isolates of soil dematiaceous hyphomycetes belonging to 25 species in 14 genera were found from 24 soil samples in the Qaidam Basin, Qinghai province. Among them, Monodictys qaidamensis and Stachybotrys variabilis are new species. Brief descriptions and illustrations for the new taxa are given. The other 23 species previously reported from China are also listed. Dried and living cultures of all fungi studied have been deposited in the Herbarium of Shandong Agricultural University： Plant Pathology （HSAUP）.
