桫椤自然保护区的虫草及其相关真菌

SOME CORDYCEPS SPECIES AND THEIR ALLIES FROM SUOLUO NATURE PRESERVE IN GUIZHOU

从贵州省赤水市桫椤自然保护区采集到虫草5种,其中新种3个:赤水虫草Cordyceps chishuiensis Liang & Liu, 桫椤虫草Cordyceps suoluoensis Liang & Liu和柄壳虫草Cordyceps stipillata Liang & Liu。赤水虫草和其近缘种的主要区别是子座直接从寄主的头部或腹部长出,单生,分枝,子囊壳广拟卵形,无喙。桫椤虫草的主要特征为子囊孢子具细丝状、柱状和囊状等多种形状,子囊孢子在子囊中呈绳状排列。柄壳虫草以子座柄分枝,子囊壳有柄和子囊孢子较粗(2祄)与其近缘种相区别。模式标本保存于贵州大学真菌资源研究室(LFRGU)

Five species of Cordyceps were collected from Suoluo Preserve,Chishui County,Guizhou Province in China.In which Cordyceps chishuiensis Z.Q.Liang et A.Y.Liu, Cordyceps suoluoensis Z.Q.Liang & A.Y.Liu and Cordyceps stipillata Z.Q.Liang & A.Y.Liu are new species.The distinguishing features of Cordyceps chishuiensis are: stroma directly originating from a host,single,branched,perithecia broadly ovate, without a cap structure.The characters of Cordyceps suoluoensis are: ascospores with filiform or cylindrical,twistily arranged in ascus.Cordyceps stipillata may be characterized by its branched stroma,perithecia with a short stipe and wider (2祄) ascospores from relative species. Specimens examined are deposited in the Laboratory of Fungus Resources, Guizhou University (LFRGU)
