山西土壤中的暗色丝孢真菌Ⅰ

摘要

从山西省不同地区采集混合土壤样品45份,从中分离获得49个暗色丝孢菌分离物,经鉴定分属于27属中的36种.其中包括1个新种,草原链格孢Alternaria pratensis;1个中国新记录属,锥梗围瓶孢属Chaetopsina;5个中国新记录种:锥梗围瓶孢Chaetopsina fulva、长椭暗双孢Cordana oblongispora、短小腐质霉Humicola brevis、伦德伯格小粘束霉Leptographium lundbergii和亚简黑乌霉Memnoiella subsimplex;其余30个为中国已知种.除对新种进行拉丁文描述和图示外,对中国新记录种也作了简要描述和描绘,对30个国内已报道种则只作分布和生境的引证.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).%A total of 49 isolates of soil dematiaceous hyphomyeetes belonging to 36 species in 27 genera were found from Shanxi Province. Among them, Alternaria pratensis is a new species, while Chaetopsina is a newly recorded genus for China; Chaetopsina fulva, Cordana oblongispora, Humicola brevis, Leptographium lundbergii and Memnoiella subsimplex are newly recorded species for China. The other 30 previously reporded species from China are also listed. Specimens (dried cultures) and living cultures of all fungi studied have been deposited in the Herbarium of Shandong Agricultural University: Plant Pathology (HSAUP).
