中国横断山的地衣研究 (6)

通过对灰梅属(Canoparmelia)表型与基因型相结合的研究，澄清了云南南部报道的珊瑚大叶梅(Parmotrema conformatum)是裂芽灰梅(Cecaperata)的错误鉴定。由于珊瑚大叶梅和裂芽灰梅在经典分类鉴别上容易混淆，通过rDNA ITS序列的系统发育分析，证明了裂芽灰梅与粉芽灰梅(Ctexana)及同心灰梅(Cconcrescens)有较近的亲缘关系；首次记录了粉芽灰梅在云南的分布范围；文中对两个新记录种进行了详细描述和讨论，并给出了中国已知灰梅属的检索表。

Contributions to the Lichen Flora of the Hengduan Mountains,China (6): Revisional Study of the Genus Canoparmelia (Lichenized Ascomycota,Parmeliacaea)

A revision of Canoparmelia from the Hengduan Mountains (Yunnan, China) revealed the occurrence of Cecaperata, based on specimens previously identified as Parmotrema conformatum. Cecaperata is hereby reported as new to the flora of China. The study also led to the identification of Ctexana as a component of the flora of Yunnan. In order to make sure the systematic position of these species, a phylogenetic analysis of rDNA ITS sequence was also carried out in this paper, indicating that Cecaperata is closely related to Ctexana and Cconcrescens. Detailed information and discussion of these two new records are provided, together with a key to all the known taxa of Canoparmelia recorded from China. Following our revision, Parmotrema conformatum should be excluded from the flora of China.
