【摘要】 从黄河源头下游8县区采集的24份土壤样品中分离得到19属34种暗色丝孢真菌,其中长孢齿梗孢Scolecobasidium longisporum和戈壁维罗纳霉Veronaea gobica为两个新种,芦竹节菱孢Arthrinium arundinis为一个新组合名称,并对灰色瓶霉Phialophora cinerescens进行了补充描述。对该地区31个中国已知种亦作了标本引证。所研究真菌的干制培养物及活菌种保存在山东农业大学植物病理学标本室(HSAUP)。更多还原

【Abstract】 Forty-five isolates of dematiaceous hyphomycetes belonging to 34 species in 19 genera were obtained from 24 soil samples collected from eight counties in the area of Yellow River source.Of these,Scolecobasidium longisporum and Veronaea gobica are new species.A new combination,Arthrinium arundinis is made.A supplementary description is given to Phialophora cinerescens,which has not been fully described from China.The other 31 taxa previously reported from China are also listed.Dried and living cultures of all the fungi studied have been deposited in the Herbarium of Shandong Agricultural University:Plant Pathology(HSAUP).更多还原
