The Resource Investigation And Distribution Of The Macrofungi In Longgang Mountains Of Wandianzi,Liaoning

Fungi are an important part of the ecosystem and play a decisive role in the material and energy cycle of the ecosystem.The number of the plant species and the biodiversity are very rich,but the investigation of the macrofungi is poor in Longgang mountains of Wandianzi.To improve the resource and provide the basic data of the macrofungi in this area,this investigation is done.The results are as follows.1.With the method of random investigation,a study was carried out on the macrofungi resource in Longgang mountain of Wandianzi between 2014 and 2015.The locations of the study was selected at Yangshuwang,Hunheyuan,Fang huolou,Dashahe,Gongqu,Dawenzihao and Xiaowenzihao.The major forest type of the study was broadleaf mixed forest type,coniferous mixed forest type,oak forest type,larch forest type,pinus koraiensis forest type,pinus tabulaefoimis forest type,Juglans mandshurica forest type.964 samples was collected in this research,and a total of 347 species belonging to 2 phulum,8 class,24 order,77 families and 159 genera were identified,including 35 species belonging to 26 genera of Ascomycota and 213 species belonging to 133 genera of Basidiomycota.And 81 of the species are new to Liaoning,2 of the species are new to China.The new species of China are Lycoperdon nigrescens Pers.and Ramaria concolor(Corner)R.H.Petersen,Biblthca My col.2.This paper discusses the methods of plant composition analysis and macrofungi composition analysis and the application of the methods in the analysis of macrofungi composition.With the analysis of plant composition,it is found that few genus family(2-5 genus)is the main component in the species of family.few species family(2-9 species)and the middle species family(10-19 species)are the main components in the species of genus.With the analysis of the macrofungi composion,the dominant families of the macrofungi(?10 species)have 11 families which accounted for 14.29%of all families and 176 species which accounted for 50.72%of all species.The dominant genera(>5 species)have 19 genera which accounted for 11.95%of all genera and 151 species of all species.3.The floristic geographical elements of the genus in the plots have 5 disrtibution types.The floristic elements in this area belong to the temperate zone,which is mainly including the worldwide distribution and the North temperate distribution.In the similarity comparison with the adjacent area of Longgang mountain of Wandianzi,the distribution of the macrofungi have continuity and difference in large areas.4.The distribution of the macrofungi in different forest type shows that the species of the macrofungi are more distributed in oak and broadleaf mixed forests,and are less distributed in pinus koraiensis and pinus tabulaeformis forests.The coniferous mixed forest has moderate distribution.The macrofungi are concentrated in the altitude of 500?800 m and he number of macrofungi varies in different altitudes.The occurrence of macrofungi in different seasons is different,mainly in July and August.In June,the macrofungi are more polyporaceae,while there had more fruiting body of Agaricaceae,Polyporaceae and Psathyrellaceae in July.More fruiting body in August are Agaricaceae,Boletaceae,Russulaceae and richolomataceae,and the fruiting bodies in September are mainly Tricholomaceaceae and Polyporaceae.
