摘要

Two new species of the genus Helminthosporium Link in Sichuan Provinice are reported.They are Helminthosporium spurirostrum and Helminthosporium sichuanense. Latin diagnoses,English descriptions and illustrations of the two new species are presented. Type specimens are deposited in the Herbarium of Shandong Agricultural University: Plant Pathology (HSAUP).%报道生于四川省枯树枝上的长蠕孢属两个新种,假喙长蠕孢Helminthosporiumspurirostrum和四川长蠕孢Helminthosporium sichuanense.假喙长蠕孢的分生孢子可产生假喙,这是首次报道长蠕孢属的一个新的特征.四川长蠕孢与黄檀长蠕孢Hdalbergiae较相似,但是黄檀长蠕孢的分生孢子大(长58-125 μm,宽12-14μm),分生孢子梗细(宽10-12μm).研究标本保存在山东农业大学植物病理学标本室(HSAUP).
