Forest Ecosystems 2022年第4期9卷 540-546页

作者： Fang Wu Xiaowu Man Ablat Tohtirjap yucheng dai Institute of Microbiology School of Ecology and Nature ConservationBeijing Forestry UniversityBeijing100083China

Background:Polypores as components of forest ecosystems are an important group of wood-inhabiting fungi playing a key role in forest regeneration. Previously, studies on polypore funga and diversity were focused on limited areas within one land mass only. What are the polypore funga and species composition for large-scale of China, North America and Europe? The funga and species composition of polypores in the three land masses will supply an important source of reference for the distribution patterns of polypores at species level or higher taxa. In the present study the diversity and species composition of polypores in China, North America and Europe are compared based on published ***:The species diversity, species composition, major genera and nutritional modes of polypores in the three land masses are comparatively ***:A grand total of 1,337 polypore species, belonging to 11 orders, 43 families and 168 genera, have been recorded in these three land masses of the Northern Hemisphere, of which 854 species occur in China, 547 species in North America, and 432 species in Europe. Polyporales, Hymenochaetales and Russulales are the three major orders, and Hymenochaetaceae, Polyporaceae, and Fomitopsidaceae are the three major families. The brown rot fungi Antrodia and Postia have highest number of species at generic level in the three land masses. The proportionally highest number of white rot polypore species is in China (78.81%), followed by North America (73.86%)and then Europe (67.82%);conversely, the proportion of brown rot polypores is highest in Europe (28.47%) then North America (21.39%) and then China (15.57%).Conclusions:China had the highest polypore diversity followed by North America, and then Europe although North America is around twice as big as China and Europe. White rot is the major nutritional mode of all the polypores in China, North America and Europe accounting for 77.04%of all polypore species. The white rot species as a p

Chinese Forestry Science and Technology 2005年第3期4卷 94-98页

作者： HUANG Mingyun dai yucheng Institute of Applied Ecology Chinese Academy of Sciences Shenyang 110016 P.R. China Graduate School Chinese Academy of Sciences Beijing 100039 P.R. China

Poroid Aphylloporales’ growth on Quercus mongolica in Northeastern China wasinvestigated during 1993-2004. The wood of the Mongolian oak seems to be good substratum forpolypores, and 75 species were recorded from the tree or its wood. Out of them 21 species (ca. 28%)are considered as rare species, 30 species (ca. 40%) as occasional species, and 24 species (ca. 32%) ascommon species. Ten species are the pathogens on the Mongolian oak. Most of the polypores werefound on other trees as well, but 14 species live exclusively on Q. mongolica.
