中国腹枝衣属地衣的3个新记录种

Three new records of the lichen genus Herpothallon from China

摘要: 腹枝衣属（Herpothallon）分布在全球热带及亚热带地区，多生于潮湿、避光处。通过野外调查、采集，综合运用形态、解剖和化学等方法对该属地衣进行了分类学研究。发现中国新记录种3个，分别为灰色腹枝衣（H. cinereumG. Thor）、日本腹枝衣（H. japonicum(Zahlbr.) G. Thor）和昆士兰腹枝衣（H. queenslandicum(Elix) Elix）。描述了它们的分类学特征，提供了外部形态图，并编制了中国腹枝衣属地衣的分种检索表。

Abstract: The genusHerpothallonis distributed in tropical and subtropical regions worldwide, primarily inhabiting moist, shaded areas. Through field surveys and collection of lichen samples, a taxonomic study was conducted based on morphological, anatomical, and chemical analyses. Notably, three new records for China were discovered, includingH. cinereum,H. japonicum, andH. queenslandicum. Their taxonomic characteristics are described, accompanied by photographs, and a comprehensive key for all knownHerpothallonspecies in China is provided.
