摘　　要：该研究对拉萨地区的大型真菌物种资源进行了多样性调查,共采集获得大型真菌标本209份,鉴定出157个种,其中包括担子菌门155种,子囊菌门2种。统计发现其中种类数量最多的是担子菌门的球盖菇科和丝盖伞科,其中食、药用菌6种,毒蘑菇4种。与中国生物多样性红色名录进行了比对,本次调查得到无危物种(LC)有34种,数据不清(DD)有27种,其他均为没有报道的种类。同时研究还发现了铦囊蘑属两个中国新纪录种,Melanoleuca ammophila沙地铦囊蘑(本文新拟)和Melanoleuca galbuserae加氏铦囊蘑(文章新拟),对其进行形态学和分子系统学分析研究的结果展示了拉萨地区大型真菌有丰富的物种多样性和挖掘空间。In this study,the diversity of macrofungal species in Lhasa was investigated.A total of 209 macrofun-gal specimens were collected and 157 species were identified,including 155 species of Basidiomycetes and 2 spe-cies of Ascomycetes.The statistics showed that the largest number of species were in the families Globular Agari-caceae and the Inocybaceae of the phylum Basidiomycetes,including six species of edible and medicinal mush-rooms and four species of poisonous mushrooms.According to the comparison with Redlist of China's Biodiver-sity,34 species of Least Concernd and 27 species with Data Deficient were obtained in this survey,and the rest of other species have not been reported.At the same time,two new Chinese record species of the genus Melano-leuca,named as Melanoleuca ammophila(newly proposed in this paper)and Melanoleuca galbuserae(newly pro-posed in this paper)were discovered in this study,and their morphology and molecular systematics were ana-lyzed.The results of this study showed that macrofungi in Lhasa area have rich species diversity and develop-ment space.
