Studies On The Macrofungal Diversity In Mt. Laoyeling Of Jilin

Species diversity, flora diversity and relation between season and vegetation in the Laoyeling Moutain were studied systematically in this paper.More than 400specimens were collected, and 261species were identified. According to morphological classification, 261 species belong to 117genera, 52families, 16orders and 2 classes. Among them 240species from 12 orders, 43 families, 101genera belong to Basidiomycota; 21species from 1 classes, 4 orders, 9families 15 genera belong to Ascomycota. There are 1 unknow species of Inocybe and 4 new species to Jilin Province. The diversity catalogue of these 261 species was arranged according to Dictionary of Fungi (2001, 9th), and the voucher specimens were deposited in the Herbarium of the Mycological Institute, Jilin Agricultural University (HMJAU).The result of the flora diversity study indicated that there are rich fungi floras in the Laoyeling Moutain, 7 families which contain more than 10 species contain 142 species, occupied 57.6% total number of macorfungi in the Laoyeling Moutain and occupied 13.5% total family number. 14 genera which contain more than 5 species, 108 species in all, and occupied 41.2%, total species number, 12.0% in the total genera number. In this 14genera, contain 11 cosmopolitan, other 3 genera are North-temperature zone disperation. Regarding the species composition: 75 comopolitans occupied 28.6% total species number, 114 North-temperate zone species, occupied 43.5% total species number. And 217 Eastern Asia-North America species occupied 6.5% in the total number. 8 Temperate-Subtropical or Tropical species, occupied 3.1% total number. 14 Eurasian species occupied 5.3%. 9 Eastern-tropical (tropical, subtropical) and tropical South America species, occupied 3.4% total number. 1 Eastern Asia-South America specie, occupied 0.04% total number. 9 China-Japan in common species, occupied 3.4% total number, and 1 Endemic specie, occupied 0.04% total number. All this suggests Laoyeling Moutain that display obvious temperate characteristics.Studies on the relation of the Macrofungal diversity and forest community and season were mainly discussed in diversity and vegetation. Vegetation of Laoyeling Moutain was classified intoâ… type,â…¡type,â…¢type andâ…£type. The macrofungi diversity in this 4 vegetation show that: (1) the proportion of common genera in total number of macrofungi in theâ… ,â…¡,â…¢andâ…£are 16.57%, 13.11%,29.63%, and 25.81%, indicate that there are difference of the macrofungi diversity in the plant vegetation diversity in 4 kinds of vegetation, coinherence with the plant vegetation diversity in the 4 kinds of vegetation. The study of seasonal changes showd that the majority of macrofungi occurred from May to October, and the numder of Species increased gradually from May to August. It reached its peak in August, then decressed.
