摘　　要：蜗孢属隶属于子囊菌门Ascomycota毛筒壳科Tubeufiaceae,它们形态特征独特,能够产生多种活性次级代谢产物,具有一定的应用前景。本研究从中国海南省采集的腐木标本上分离到3种卷旋型丝孢真菌,通过ITS、LSU、RPB2和TEF1α多基因系统发育分析证据结合形态学特征,确定了它们的分类地位。结果表明,其中2个物种为蜗孢属新种,1个物种为中国新记录。为纪念李玉院士在中国菌物学界做出的贡献,本文特将其中一个新物种命名为李玉蜗孢菌。The fungal genus Helicoma has unique morphological characteristics and potential to produce a variety of active secondary metabolites.In this paper,two new species and one new Chinese record of Helicoma are introduced based on ITS,LSU,RPB2 and TEF1αmultigene phylogenetic analyses and morphology.To commemorate the contribution of Prof.LI Yu,academician of the Chinese Academy of Engineering,to mycology,one new species is named as Helicoma liyui.
