A Preliminary Study On Macrofungal Resources In Shariwendu Nature Reserve,Inner Mongolia

Macrofungi are an important group in the biological world.Many macrofungi have high edible value and medicinal value,and have a good prospect of development and application.Through the investigation,collection and identification of macrofungi in Shariwendu Nature Reserve,Inner Mongolia,the species,fauna and community diversity of macrofungi in this area were studied for the first time,and the economic value and threat degree of macrofungi resources in the reserve were evaluated and evaluated.The conclusions are as follows:1.The Shari Wendu Nature Reserve in Inner Mongolia is rich in macrofungi resources.A total of 892 macrofungi specimens were collected,belonging to 208 species,104 genera,47 families,20 orders,5 classes,and 1 new record species was found in Inner Mongolia.2.Among the 208 species of macrofungi identified in this area,92 species of 4families were dominant,accounting for 8.51% and 44.23% of the total number of families.They were Agaricaceae,Polyporaceae,Tricholomataceae and Russulaceae.The dominant genera with 5 or more species were 69 species in 9 genera,accounting for8.65% of the total genera,including Russula,Clitocybe,Geastrum,Melanoleuca,Lycoperdon,Inocybe,Trametes,Agaricus and Marasmius.There were 125 species in 53 genera in the reserve,and 57 species in 30 genera in the north temperate zone,accounting for 56.99% and 32.26% of the total number of known flora,respectively.Subtropical and tropical elements,East Asian and North American elements were relatively small in the reserve.Compared with the flora of other areas,the composition of this reserve and Saihanwula National Nature Reserve District was the most similar,with a similarity coefficient of 64.20%.3.Sand daily temperature was 5 vegetation community nature reserve for the huge fungal diversity,richness and evenness index are different,the community I(native broad-leaved forest)large fungi diversity and richness index is the highest,followed by subsequent community ?(secondary broad-leaved forest)> community IV(plantation)>community ?(coniferous forest)>community V(shrub).The evenness index change is a bit different,for the community I > community ? > community IV > community V >community ?.About 40%?70% of the endemic species were found in each community,which indicated that the composition of macrofungi was relatively different in the five communities,and the occurrence and distribution of macrofungi were significantly affected by different habitat conditions.4.A total of 45 species of edible fungi,33 species of medicinal fungi,27 species of edible and medicinal fungi,31 species of unknown edible and poisonous fungi,and 53 species of large fungi whose economic value was not reported were found in the reserve.There were 105 species of edible and medicinal macrofungi,50.48% of the total species.Among them,there were 2 species of endangered macrofungi,158 species of non-endangered macrofungi,42 species of macrofungi with insufficient data,and 6species of macrofungi were not evaluated.The two near risk large fungi in the protection of black and white bag Melanoleuca melaleuca(Pers.)Murrill,tree Lingue Ganoderma applanatum(Pers.)Pat.
