Abstract: Pinus massoniana and Pinus taiwanensis are the most common and important tree species in the Huangshan Mountain district,and ectomycorrhizae plays an important role in their forestation.Our investigations in 1998～2003 showed that under the pine forests of this district,there were 43 species of ectomycorrhizal fungi belonging to 10 families and 17 genera,of which,43 were under Pinus massoniana forest, and 12 under Pinus taiwanensis forest.Only a few species were found under young Pinus massoniana forest,with the dominant of Pisolithus tinctorius (Pers.) Coken and Rhizopogon spp.,but under mature Pinus massoniana forest, there were plentiful species,with the dominant of Russulaceae, Amanitaceae,Boletaceae and Canthurellaceae.The relationships between woody species and ectomycorrhizal fungi,and between fungi distribution and temperature,moisture and soil condition were discussed in this paper,which would benefit to the further studies on the effects of different ectomyrrhizal fungi to Pinus massoniana and Pinus taiwanensis forests.
