摘　　要：从华西箭竹病理组织上分离到一株真菌,通过对其产孢模式和分生孢子特点等的形态学研究,发现该菌为链格孢属小孢子种群成员。然而该菌具有区别于已知种的特征,如分生孢子梗常单生,少数成簇,无分枝;分生孢子大多单生,较少链生,孢身较大;寄主为华西箭竹,故立为竹链格孢新种。该模式标本保藏于山东理工大学生命科学学院实验室。A fungus was isolated from the pathologic tissue of Fargesia nitida. Based on its morphological studies, such as sporulation patterns and conidia characteristics, the authors found that the strain was a member of small-spored Alternaria species. However, the strain was distinguished difference from the others： Its conidiophores were usually single, sometimes clustered, without divarication. Most of its conidia were single, seldom in chain, with the size larger than the relatives. Its host was Fargesia nitida, a clumping bamboo. So it was a new species. A hernaria bambusicola sp.nov.was proposed for the fungus.The dry culture was preserved in the lab of school of life science,Shandong University of Technology.
