中国盔孢伞属的分类

Taxonomy of the genus Galerina(Hymenogastraceae,Agaricales)in China

根据采自全国20个省、自治区的盔孢伞属Galerina真菌标本整理、鉴定,确认出36种,其中包含28个已知种和8个中国新记录种。对中国新记录种褐柄盔孢伞G.badipes、帆孢盔孢伞G.calyptrata、迦佩盔孢伞G.jaapii、假拟提灯藓盔孢伞G.pseudomniophila、沼泽盔孢伞G.paludosa、泡孢盔孢伞G.physospora、萨列里盔孢伞G.sahleri和胫囊盔孢伞G.tibiicystis进行了详尽的形态学描述,提供了原生态照片和显微特征线条图以及分亚属、分种检索表。通过相关研究材料进行DNA提取,所得21条ITS序列与73条下载序列利用贝叶斯法及最大似然法构建系统发育树,验证鉴定结果的准确性。

Collections made from 20 provinces and autonomous regions of China were studied,and 36 species were identified,including 28 known species and 8 species are new to China.Morphological description,drawings,photos and discussion were provided for the new records species,namely G.badipes,G.calyptrata,G.jaapii,G.pseudomniophila,G.paludosa,G.physospora,G.sahleri,and G.tibiicystis.DNA sequences were extracted from the Chinese materials,21 newly generated ITS sequences and 73 download sequences were obtained.Phylogenetic tree was constructed by Bayesian inference and Maximum likelihood analysis,and the identification results of new record species were verified by the molecular data.
