摘要(Abstract)：

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。
