Echinoplaca infuscata sp. nov. and new records of the genus Echinoplaca from Yunnan, China

Abstract

Three Echinoplaca spp. are reported from China. The new species Echinoplaca infuscata is characterised by pale brown apothecia having different morphologies and colors at different growth stages, and (3–)5-septate ascospores. Echinoplaca epiphylloides and E. intercedens are reported as new from China. The macromorphology, micromorphology, secondary chemistry, ecology, and distribution ranges of these three species are presented and discussed. A key is provided to the Echinoplaca species known in China.
