Abstract

The lichenised fungal genus Pyrenula is a very common crustose lichen element in tropical to subtropical forests, but little research has been done on this genus in China. We carried out an integrative taxonomic study on Pyrenula in China using morphological, anatomical, chemical characters, and molecular data (ITS, nuLSU, mtSSU). Three new species with muriform ascospores containing red oil when over-mature were found: Pyrenulasubmacularis sp. nov., P.yunguiensis sp. nov. and P.rufotetraspora sp. nov. Molecular data and TLC results of P.macularis and P.breutelii are for the first time reported and show that they are not synonyms. This is the first report of P.breutelii in China. Contrary to the previous reports of this genus, we found lichen substances in all the five species in this study, seemingly terpenoids. A key for the Pyrenula species reported in China is provided.

系统进化分析表明，Pyrenula（Pyrenulaceae）的多样性比预期的要大：在中国发现了三个新种和一个新记录。

地衣真菌Pyrenula属是热带至亚热带森林中一种非常常见的壳层地衣，但中国对该属的研究很少。我们利用形态学、解剖学、化学特征和分子数据（ITS、nuLSU、mtSSU）对中国的Pyrenula进行了综合分类研究。发现了三个新种，它们的榈状囊孢子在过度成熟时含有红油：Pyrenulasubmacularis新种、P.yunguiensis新种和P.rufotetraspora新种。首次报告了P.macularis和P.breutelii的分子数据和TLC结果，表明它们不是同物异名。这是中国首次报道P.breutelii。与之前关于该属的报道相反，我们在本研究的五个物种中都发现了地衣物质，似乎是萜类化合物。本文提供了中国报道的 Pyrenula 物种的检索表。
