We describe two new species of (Dermateaceae, Ascomycota), and , which are discovered in China. sp. nov. is distinct in producing 2-3 stipitate apothecia on a basal stroma with a light yellow hymenium, broadly ellipsoid 0-1(-2)-septate ascospores, and divergent DNA sequence data. sp. nov. is characterized by sessile apothecia, 0.3-0.8 mm in diam, a yellowish hymenium, J+ asci 135-170 × 15-21 μm, multiseptate ascospores, 33-48 × 7-10.3 μm, and growing on rotten bamboo. In addition, and are reported for the first time from China, and 11 species previously reported from China are reviewed and briefly noted, of which one was a misidentified species. Phylogenetic analyses inferred from ITS nrDNA sequences confirm the placement of and in the genus .
我们描述了在中国发现的皮盘菌科（子囊菌门）的两个新物种，即新种1和新种2。新种1的独特之处在于在基部基质上产生2 - 3个具柄子囊盘，子实层浅黄色，具宽椭圆形、0 - 1（- 2）隔膜的子囊孢子，以及不同的DNA序列数据。新种2的特征为无柄子囊盘，直径0.3 - 0.8毫米，子实层淡黄色，J +型子囊135 - 170×15 - 21微米，具多个隔膜的子囊孢子，33 - 48×7 - 10.3微米，生长在腐烂的竹子上。此外，物种3和物种4首次在中国被报道，对之前在中国报道的11种物种5进行了综述并简要说明，其中有一种是错误鉴定的物种。基于ITS nrDNA序列的系统发育分析证实了新种1和新种2在属名中的位置。
