Macrofungal diversity in broad-leaved Korean pine forest was investigated in Changbaishan National Nature Reserve. Sampling survey method was adopted to obtain the basic data of species composition and community structure in different plant communities with Pinus koraiensis. The interval of two released collection surveys is about fifteen days. Five plant communities were divided according to references and the compositions of plant species. They are: Ass. Quercus mongolicus+Pinus koraiensis+Picea jezoensis var. komarovii, Ass. Pinus koraiensis+Acer mono+Quercus mongolicus, Ass. Pinus koraiensis+Acer pseudo-sieboldianum+Tilia mandshurica, Ass. Pinus koraiensis+Acer ukurunduensis+Tilia amurensis and Ass. Pinus sylvestriformis+Pinus koraiensis+Albizia kalkora. The fungal specimens were identified with morphological taxonomic methods and deposited in the Herbarium of Mycology of Jilin Agricultural University (HMJAU). In order to assess the macrofungal diversities in the different communities and compare their differences, index of species richness (R1, R2), species diversity (N1, N2, H′) and species evenness (E) were used to analyze all the collected data. The results showed that: (1) 238 species of macrofungi belonging to 90 genera of 44 families were identified; among them, 100 species were ectomycorrhizal, 135 were saprophytic, and 3 belonged to other types. (2) The endemic species of each plant community occupied from 38.03% to 49.41% individually, and the common species occurring in all the plant communities shares 5.81%-7.04%; such a result indicates that the habitat heterogeneity existing in broad-leaved Korean pine forest of Changbaishan National Nature Reserve contributes a lot to the spatial distribution of macrofungi there. The species richness index (R1, R2), species diversity index (N1, N2 and H′) and evenness index (E) are different from each other among the plant communities. The Ass. Quercus mongolicus+Pinus koraiensis+Picea jezoensis var. komarovii has the highest species richness index and species diversity index; while the Ass. Pinus koraiensis+Acer mono+Quercus mongolicus gained the highest evenness index. (3)There are two fruiting peak seasons for the macrofungi each year, the first fruiting peak occurrs during the middle and late of July, species of Mycena, Marasmius and Russula were common in this period; the second fruiting peak occurrs during the first ten days of September when Mycena, Inocybe, Clitocybe and Hebeloma were the dominant genera. The saprophytic species occupied 89.09% of all the species occurring in the 1st fruiting peak and the ectomycorrhizal species were more common in the 2nd fruiting peak. Such a result could give some predictive informations to the mushroom hunters. From the view of fungal conservation, the Ass. Quercus mongolicus+Pinus korainesis+Picea jezoensis var. komarovii is the key and ideal zone for in situ conservation, which needs to pay more attention. The best way to preserve mycorrhizal species is to preserve the living trees they associated with, and the preservation of diverse woody debrises may play an important role in conserving saprophytic species.
