【摘要】 石蕊属地衣初生地衣体鳞片状、次生果柄圆柱形，世界上报道了500多种，是地衣多样性的重要组成部分，并具有重要的生态功能。在深入研究中国石蕊属地衣过程中，基于形态学特征、化学特征和nrDNA ITS序列的系统发育分析，从采集于河北省和云南省的地衣标本中发现了石蕊属地衣2个中国新记录种——喀麦隆石蕊(Cladonia camerunensis)和覆瓦石蕊(C.imbricata)。该文提供了2种石蕊属地衣特征的详细描述和图片并与相近种类进行比较。更多还原

【Abstract】 Lichens of the genus Cladonia consist of primary squamules and secondary cylindric podetia. More than 500 species have been reported in the world, which are the important components of lichen diversity and have significant ecological functions. With the in-depth investigation of Cladonia species in China, we identified C. camerunensis and C. imbricata as new to China based on morphological characteristics, chemistry and phylogenetic analysis of nrDNA ITS sequence data from Yunnan and Hebei, respectively. Detailed characteristics and pictures of two Cladonia species are presented with comparison with some similar species.更多还原
