Floristics and ecology of Myxomycetes in China 2. Mycofloristic Ties

Abstract

The total taxa of myxomycetes known from China included 412 species varietas and subspecies, which belonged to 6 orders, 11 families, and 38 genera and occupied about 2/3 of those of the world, so China was one of the countries rich in myxomycetes. The genera that had more than 10 species were Physarum (97 species), Arcyria (37 species), Stemonitis (34 species), Didymium (32 species), Cribraria (29 species), Diderma (23 species), Trichia (21 species), Comatricha (21 species), Licea (15 species), Hemitrichia (14 species), Badhamia (12 species), and Perichaena (11 species). Moreover, there were 4 genera with 5-9 species, 10 with 2-4 species, and 12 with only a single species. The provinces with more than 50 species were Taiwan (236 species), Jilin (199 species), Fujian (106 species), Heilongjiang (91 species), Inner Mongolia (88 species), Hebei (88 species), Guangxi (73 species), Shaanxi (73 species), Hainan (56 species), Hubei (52 species). The richness of the Northeast and North of China were great; comparatively, the Southwest and Northwest still needed more investigation. The distribution patterns of the taxa were mainly cosmopolitan and northtemperate species; and the characters of distribution were more obvious.
