内蒙古罕山国家级自然保护区大型真菌多样性

本文对内蒙古罕山国家级自然保护区800余份大型真菌标本进行了研究,结合形态特征和ITS序列鉴定出308种,隶属于2门4纲14目45科108属。在科属组成上,优势科为红菇科Russulaceae、蘑菇科Agaricaceae、丝盖伞科Inocybaceae等共8科,含195种,分别占总科数、总种数的17.78%和63.31%;优势属为红菇属Russula、丝盖伞属Inocybe、蘑菇属Agaricus等共15属,分别占总属数、总种数的13.89%和54.87%。在地理分布上,以世界广布种和北温带分布种为主,分别含有128种和107种,占总种数的41.56%和34.74%,表现出明显的北温带区系特征,但不同植被类型中大型真菌多样性差异显著。

Macrofungal diversity in Hanwula National Nature Reserve,Inner Mongolia

Macrofungi in Hanwula National Nature Reserve in Inner Mongolia were investigated. More than 800 specimens collected represent 308 species belonging to 108 genera, 45 families, 14 orders, 4 classes, and 2 phyla based on morphological identification and ITS evidence. Among them, 195 species in 8 families were dominant. Russulaceae, Agaricaceae and Inocybaceae account for 17.78% of the total families, containing 63.31% of the total species. Of the 15 dominant genera (containing 169 species) Russula, Inocybe and Agaricus (accounting for 13.89% of the total genera) make up 54.87% of the total species. Foristic analysis indicated that 128 species were cosmopolitan and 107 north-temperate, occupying 41.56% and 34.74% of the total species respectively. The results suggest that Hanwula National Nature Reserve region shows fundamentally north-temperate mycogeographically, but the macrofungal diversity varies with different vegetation types.
