Diversity Of Macrofungi In The Greater And Lesser Khinggan Moutains

The catalogue of macrofungi,mycobiota of macrofungi in the Greater and Lesser Khinggan Moutains were studied in this thesis.A total of 3363 macrofungi speciemens were collected,and 713 species belonging to 2 phylum,5class,21 orders,65 families,197 genus were identified.Among them,265 species were edible,158 species were medicinal and 125 species were poisonous.One new species and eleven species new to China were discribed.The species catalogue was arranged according to the taxonomic system of Dictionary of the Fungi(10^th edition)and Index Fongorum.In the part of mycobiota composition,there are 17 dominant of families containing equcal and more than 10 kinds of species,accounting for 26.15% of the total number of families,and the total number of species was 527,accounting for 73.91% of the total number of all macrofungi species of the Greater and Lesser Khinggan Moutains.There were Agaricaceae,Cortinariaceae,Entolomataceae,Hygrophoraceae,Inocybaceae,Lyophyllaceae,Marasmiaceae,Mycenacea,omphalotaceae,Pluteaceae,Psathyrellaceae,Strophariaceae,Tricholomataceae,Boletaceae,Suillaceae,Russulaceae,Polyporaceae.Besides,Amanitaceae,Hydnangiaceae,Pleurotaceae,Auriscalpiaceae,Gomphaceae,Hymenochaetaceae,Fomitopsidaceae also occupies an important position in this region.There are 48 families containing less than 10 kinds of species,but the total number of species only was186,accounting for 26.08% of the total number of all macrofungi species of the Greater and Lesser Khinggan Moutains,occupies a subordinate position in this region.There are 34 dominant genera which contains equcal and more than 5 species.There were Helvella,Agaricus,Lepiota,Lycoperdon,Amanita,Cortinarius,Entoloma,Laccaria,Hygroporus,Crepidotus,Inocybe,Lyophyllum,Marasmius,Mycena,Gymnopus,Pluteus,Psathyrella,Galerina,Gymnopilus,Hebeloma,Pholiota,Clitocybe,Lepista,Melanoleuca,Tricholoma,Panaeolus,Leccinum,suillus,lactarius,Russula,Ramaria,Geastrum,Polypores,Trametes.Accounting for 17.25% of the total number of genera,446 species,accounting for 62.25% of the total number of all macrofungi speciesIn the respect of the floristic composition in the Greater and Lesser Khinggan Moutains.There are eight distribution types in this reigon,there were world-wide distritbution,North temperate zone distritbution,Eurasia continent distritbution,East Asia-North America disjunctive distritbution,North temperate zone-Austrilia distritbution,Temperate-subtropical and tropical distritbution,East Asia Distritbution,China endemic species This reigon are mainly with the north temperate zone distribution,world-wide distribution,Eurasia continent distribution.Among them,182 species are belong to the world-wide distritbution,occupy all species of the Greater and Lesser Khinggan Moutains 25.53%;237species are belong to the north temperate zone distribution,occupy all species of the Greater and Lesser Khinggan Moutains 33.24%;165species are belong to the Eurasia continent distribution,occupy all species of the Greater and Lesser Khinggan Moutains 23.14%.Others,species of East Asia-North America distribution,North temperate zone-Austrilia disjunctive distribution are else occupied certain proportion.But,the Greater and Lesser Khinggan Moutains are mainly with north temperate zone distribution,world-wide distribution,Eurasia continent distribution according to the results.
