腔孢纲一新属--类腊肠茎点霉属

摘要

A new genus in Coelomycetes, Allantophomoides is reported. The type species, Allantophomoides carotae S. L. Wei et T. Y. Zhang sp. nov., causes severe leaf spots of Daucus carota var. sativa DC. (Umbelliferae) in Gansu Province. Type Specimen is deposited in Herbarium of Shandong Agricultural University: Plant Pathology (HSAUP).%近年甘肃省河西走廊一带胡萝卜上发生一种叶斑病,严重时造成减产20%~30%.其病原物为丝分孢子真菌(半知菌)腔孢纲Coelomycetes中一未描述的真菌.该菌具有分生孢子器,但其形态与相似属茎点霉属Phoma、鞘茎点霉属Coleophoma和拟腊肠茎点霉属Allantophomopsis不同,遂建立类腊肠茎点霉属Allantophomoides(新属);其模式种为胡萝卜类腊肠茎点霉Allantophomoides carotae(新种).研究的标本保存在山东农业大学植物病理学标本室(HSAUP).
