| 摘要: |
| 该研究对采自于我国的200余份赤星衣属(Haematomma)地衣标本利用形态学、化学、生态学等特征进行了综合研究,发现赤星衣属一新种和一中国新记录种。新种为砖壁赤星衣(H. muriformis R. Tang & Z. J. Ren),主要特征为子囊盘红色,孢子砖壁型,较宽(75～87.5×12.5～20 μm),所含化学物质为atranorin、haematommone 和arthothelin。中国新记录种为马托赤星衣(H. matogrossense Kalb & Staiger)。该文对新种和中国新记录种进行了详细的特征描述,提供了形态和解剖照片,同时提供了已知中国赤星衣属地衣物种的检索表。该研究充实了赤星衣属地衣的数据信息资源库,为《中国地衣志》的编写提供了基础资料。 |

| Abstract: |
| The present study of genus Haematomma from China was based on morphological, chemical and ecological charactersistics. More than 200 lichen specimens of Haematomma from China were studied. Haematomma muriformis R. Tang & Z. J. Ren is described as a new species. It is characterized by large muriform ascospores(75-87.5×12.5-20 μm)and the production of atranorin, haematommone and arthothelin. While, Haematomma matogrossense Kalb & Staiger is found from China for the first time. Based on detailed studies, morpholegical and anatomical photos and a key to all known Chinese Haematomma species are provided. The present study is very important for clarifing the species composition and local distribution of lichens of Haematomma in China and provides the basic information for the Lichen Flora of China. |
