Studies On Macrofungi Diversity Of Baishilazi National Nature Reserve In Liaoning Province

Macrofungi diversity and the relationship between macrofungi diversity and season as well as forest vegetation in Liaoning Baishilazi National Nature Reserve were studied systematically in this paper.In species diversity, more than 610 specimens were collected in Liaoning Baishilazi National Nature Reserve and 217 species were identified. According to morphological classification, 217 species belong to 105 genera,41 families,15 orders,4 classes,2 Phylum. Among them: 201 species from 11 orders, 34 families, 94 genera belong to Basidiomycota; 16 species from 3 classes, 4 orders, 7 families 11 genera belong to Ascomycota(Incertae classes and orders are not included.). There are 38 new recorded species to Northeast of China, and 56 new recorded species to Liaoning Province. The diversity catalogue of these 217 species was arranged according to Dictionary of Fungi (tenth edition,2008), and the voucher specimens were deposited in the Herbarium of the Mycological Institute, Jilin Agricultural University (HMJAU).The fungi flora was very abundant in Baishilazi Nature Reserve. Agaricaceae, Tricholomataceae, Russulaceae, Polyporaceae, Strophariaceae, Marasmiaceae and Hymenochaetaceae, with 112 species, 51.6 % of the mount of macrofungi in the Baishilazi Nature Reserve, belonged to the families which were not less than 10 species and these families were widespread in the world and North Temperature Zone. Eight genera including Amanita, Cortinarius, Inocybe, Marasmius, Mycena, Clitocybe, Lactarius and Russula belonged to the dominant genera. Cosmopolitan species and North Temperature Zone species(70.96 %)were main distribution species. Eurasian species and Temperate-Subtropical or tropical species(22.58 %)also had many species.The relationships between Macrofungi diversity and forest vegetation, climate were mainly studied. According to the difference of all plant communities in Baishilazi Nature Reserve, 5 sampling plot were seted and 19 quandrats were identified in different plant communities. It also demonstrated the species diversities of macrofungi in forest quandrats of Larix gmelinii (Rupr.) Rupr., quandrats of Abies holophylla Maxim., quandrats of Pinus armandii Franch, quandrats of deciduous broad-leaf forest as well as quandrats of mixed-wide and sub-alpine conifer forest. It also illustrated that the species and quantities of macrofungi were greatly related to season in this nature reserve. It needs long term data sets to conclude the occurance of fruiting bodies affected by season, temperature and rainfall.The problem of macrofungi diversity and the measures of solving the problem were discussed in the end.
