Abstract:

Myxomycetes are widely distributed in forest ecosystems and play an important role in nutrient cycling. The diversity and distribution of myxomycetes in two forests of the Lesser Khinggan Mountains, China were examined in Tangwanghexing’anshilin Forest Park and Shengshan National Nature Reserve. A total of 248 samples of myxomycetes were collected and identified to 44 species belonging to 17 genera of eight families in four orders based on morphological characteristics. Ten new species were recorded in Heilongjiang Province, such as Craterium dictyosporum, Physarum album and Reticularia splendens var. jurana. The species diversity of myxomycetes was higher in Tangwanghexing’anshilin Forest Park (36 species) than in Shengshan National Nature Reserve (25 species). Among the 44 species, 17 species were found in both sites and the composition similarity (CS) was 55.7%. Physarum viride was the most dominant species in mixed coniferous and broad-leaved forests. Hemitrichia serpula was the most dominant species in Pinus koraiensis forest. This study suggests that vegetation type has an important influence on the species composition and diversity of myxomycetes.
