摘要

The lichenised class Lichinomycetes only includes Lichinales, which consists of three families, i.e. Gloeoheppiaceae, Lichinaceae and Peltulaceae. Results of taxonomic study on Chinese Lichinomycetes based on phenotypic characters were reported. A new species Digitothyrea subdivergens was described. Heppia solorinoides, Thyrea asahinae and Thyrea girardii were new to China. Comparison and discussion with their similar species were given. These are basic data for compiling Lichen Flora of China, and resource information for implementing ‘desert biocarpet engineering’.
