Abstract： The purpose of this study is to investigate the species diversity of Malmidea in China and further identify its species composition and distribution. Three new records of Malmidea are reported from China, M. indica (D. D. Awasthi & M. R. Agarwal) Hafellner & T. Sprib, M. reunionis Kalb and M. hechicerae Kalb. The specimens were collected from Yunnan Province. Detailed descriptions and illustrations were provided for each species. A key to all known Chinese Malmidea species was also provided. This study enrich the diversity of Malmidea in China, and has some significance for the conservation and study of lichen diversity of China.

Abstract： The purpose of this study is to investigate the species diversity of Herpothallon in China and further identify its distribution characteristics and species composition. One hundred and twenty-eight specimens of the lichen genus Herpothallon were collected from tropical and subtropical regions of China as part of our field investigations. Identification was carried out using morphological, anatomical and chemical methods. The examined specimens are deposited in the Lichen Section of the Botanical Herbarium, Shandong Normal University (SDNU) and the Herbarium of Kunming Institute of Botany, Chinese Academy of Sciences, Kunming, China (KUN). A total of 12 species of Herpothallon are reported, of which Herpothallon australasicum (Elix) Elix & G. Thor, H. granulosum Jagadeesh Ram & G. P. Sinha, H. himalayanum Jagadeesh & G. P. Sinha, H. isidiatum Jagadeesh Ram & G. P. Sinha and H. minutum Jagadeesh are new records for China. Hitherto known species of Herpothallon in China were comprehensively analyzed. The results were as follows: (1) There are two additional species of Herpothallon found in China making a total of 14 and accounting for 29.17% of the known Herpothallon species worldwide; (2) These species belong to five types of geographical element: Pantropical, Tropical Asia to Tropical Australia, Topical Asia and tropical America, Tropical Asia, and Endemic to China; ( 3) Herpothallon species in China grows mainly in the altitude ranging 300 m to 2 500 m; (4) Most of these species are mainly corticolous with a few being foliicolous, saxicolous and muscicolous in China. The results of initial filed work indicate that this group is distributed sporadically in some mountainous forests in tropical and subtropical regions of the world, and indicate a higher biodiversity of Herpothallon in southern China, changes in substrate and altitude also have important effects on the distribution of Herpothallon in China, they are important for the understanding of the genus and the protection of lichen diversity in the country. We plan to carry out further surveys and studies on this genus to provide more detailed and reliable data that can make species definition more objective and establish a more reliable classification.

Abstract：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(Haematomma muriformis)，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(Haematomma matogrossense)。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。
