中国茶渍属和石蕊属4新记录种

Four Species of Lichen Genera Lecanora and Cladonia New to China

摘要:

通过形态学及化学研究，结合nrDNA ITS序列的系统发育分析，该文报道了茶渍属(Lecanora Ach.)和石蕊属(Cladonia P. Browne)地衣4中国新记录种：莱氏茶渍(Lecanora layana Lendemer)、白头山茶渍(L. baekdudaeganensis B. G. Lee & Hur)、伪银茶渍(L. pseudargentata Lumbsch)和草皮石蕊[Cladonia caespiticia (Pers.) P. Gaertn., B. Mey & Scherb.]。该文对这些物种的分类学特征进行了详细描述，并与相似种进行了对比，同时提供了各种的地理分布图和形态图。这为中国茶渍属和石蕊属地衣物种多样性及资源利用提供了基础资料。

Abstract:

Based on combined morphological and chemical data with phylogenetic analysis using nrDNA ITS sequences, four species in the lichenized genus Lecanora Ach. and Cladonia P. Browne., including L. layana Lendemer, L. baekdudaeganensis B. G. Lee & Hur, L. pseudargentata Lumbsch and C. caespiticia (Pers.) P. Gaertn., B. Mey & Scherb. from Dabie Mountains, are reported as new record to China. The taxonomic characteristics of these species are described in detail and compared with similar species, and the geographic distribution and morphological photos are provided. These will provide information for the species diversity of Lecanora and Cladonia in China.
