我国新担子菌类补遗

Contribution to the Knowledge of New Basidiomycoteous Taxa from China

在研究甘肃、四川、云南的担子菌类时发现如下４新种：云南地红菇（ＭａｃｏｗａｎｉｔｅｓｙｕｎｎａｎｅｎｓｉｓＺａｎｇ），属红菇科（Ｒｕｓｕｌａｃｅａｅ），地红菇属（ＭａｃｏｗａｎｉｔｅｓＫａｌｃｈｂｒ．）系我国新记录；松针锈耳（ＣｒｅｐｉｄｏｔｕｓｐｉｎｉｃｏｌａＺａｎｇ）绣耳科（Ｃｒｅｐｉｄｏｔａｃｅａｅ）；蛇盖条孢牛肝菌（ＢｏｌｅｔｅｌｕｓｓｅｒｐｅｎｔｉｐｉｌｅｕｓＺａｎｇｅｔＹｕａｎ），属松塔牛肝菌［疣孢牛肝菌科］（Ｓｔｒｏｂｉｌｏｍｙｃｏｔａｃｅａｅ）；喜杉绒盖牛肝菌（ＸｅｒｏｃｏｍｕｓｐｉｃｅｉｃｏｌａＺａｎｇｅｔＹｕａｎ），属牛肝菌科（Ｂｏｌｅｔａｃｅａｅ）；长柄灰包（ＬｙｃｏｐｅｒｄｏｎｌｏｎｇｉｓｔｉｐｕｍＺａｎｇｅｔＹｕａｎ），属灰包科（Ｌｙｃｏｐｅｒｄａｃｅａｅ）。

Five new taxa of Basidiomycota are previously undescribed from Gansu, Sichuan, Yunnan of China. 1. Macowanites yunnanensis Zang (Russulaceae), the genus Macowanites Kalchbr. is a new record to China. 2. Crepidotus pinicola Zang(Crepidotaceae). 3. Boletellus serpentipileus Zang et Yuan (Strobilomycetaceae). 4. Xerocomus piceicola Zang et Yuan (Boletaceae). 5. Lycoperdon longistipum Zang et M. S. Yuan (Lycoperdaceae). The morphological differences, habitats and similarities of these new taxa are compared with closely related species. The holotypes are deposited in the Cryptogamic Herbarium, Kunming Institute of Botany (HKAS).
