Abstract:
Larch is the important coniferous species in Northern China. Many polypore species are growing on the fallen trunks of natural larch forests, which can decompose the cellulose, semi cellulose, and lignin of the fallen trunks, and promote the matter cycling and maintain the carbon balance in forest ecosystem, playing a key ecological function in forest ecosystem. Aiming at the polypore species on the 5 main larch forest species in China, this paper analyzed the species composition and distribution characteristics of polypore, and compared the polypore species diversity on different kinds of larch in China. A total of 107 polypore species were recorded, belonging to 43 genera in 11 families, among which, brown fungi accounted for 45.4% of the total collected in this study, and occupied about 50% of the whole brown fungi reported in China. 91. 7% of the polypore grew on the decaying fallen trunk. Larix gmelini had more polypore species and individuals, as compared with the other 4 larch species. There was a high similarity in the polypore community composition on L. gmelini and L. olgensisi and on L. sibirica and L. griffithiana, which was in accordance with the natural distribution of related forests.
