摘　　要：地星属Geastrum隶属于担子菌门Basidiomycota、伞菌纲Agaricomycetes、地星目Geastrales、地星科Geastraceae,因奇特的外观、生态和医药用价值吸引了国内外真菌工作者的关注。本研究对燕山地区地星种类进行了详细调查,通过形态学观察结合ITS-LSU-rpb1-atp6四基因系统发育树分析,发现并描述了该地区地星属新种2个:Geastrum yanshanense(Sect.Myceliostroma)和Geastrum beijingense(Sect.Exareolata)。此外,通过多基因结合形态学方法,发现燕山地区3个已知地星属物种,Geastrum fimbriatum、Geastrum velutinum和Geastrum schmidelii。文献记载和中国科学院菌物标本馆(HMAS)保藏的其他6种分布在燕山地区的地星需进一步分子验证。Geastrum belongs to Basidiomycota,Agaricomycetes,Geastrales,and Geastraceae.It attracted mycologists’attention by its peculiar appearance,ecological and medicinal value.Based on morphological observation combined with phylogenetic analysis of ITS-LSU-rpb1-atp6,two new species of Geastrum,G.yanshanense(in Sect.Myceliostroma)and G.beijingense(in Sect.Exareolata),were found and described from Yanshan Mountains.Three additional known species were identified,G.fimbriatum,G.velutinum and G.schmidelii.The other six Geastrum species distributed in Yanshan Mountains recorded in literature and HMAS need to be further verified by molecular methods.
