亚沉茶渍亚洲亚种Lecanora subimmersa subsp.asiatica Zahlbr.的订正研究

A Revision of the Subspecies Lecanora subimmersa subsp.asiatica Zahlbr.Reported from China

亚沉茶渍亚洲亚种Lecanora subimmersa subsp.asiatica Zahlbr.曾被基于文献研究转隶至平茶渍属(Aspicilia)或处理为亚沉茶渍原亚种L.subimmersa(Fée)Vain.subsp.subimmersa的异名,但模式标本的研究缺乏仍使该变种的概念不清。利用形态学、解剖学和化学等方法对L.subimmersa subsp.asiatica Zahlbr.的模式标本进行了综合研究,发现L.subimmersa subsp.asiatica与滇茶渍[L.oreinoides(Körb.)Hertel&Rambold]的形态特征及次生代谢产物一致,故将L.subimmersa subsp.asiatica作为L.oreinoides的异名处理。依据研究标本,对滇茶渍进行了形态学描述,同时提供了相关形态学图片,澄清了亚沉茶渍亚洲亚种的概念。

The subspecies Lecanora subimmersa subsp.asiatica Zahlbr.was treated as one subspecies Aspicilia subimmersa(Fée)Hue subsp.asiatica(Zahlbr.)J.C.Wei,or listed as a synonym of L.subimmersa(Fée)Vain.subsp.subimmersa by previous researchers.The concept of that subspecies is confusing.The specimens of L.subimmersa subsp.asiatica Zahlbr.were studied in morphological,anatomical and chemical details.The morphological characteristics and secondary metabolites of this subspecies are consistent with those of L.oreinoides(Körb.)Hertel&Rambold.Therefore,L.subimmersa subsp.asiatica should be regarded a synonym for L.oreinoides.A detailed description of L.oreinoides,and morphological photos are provided in this paper.
