There were 4 pine species in southern Viet Nam, Pinus dalatensis, P. krempfii, P. kesiya and P. latteri, distributed from altitude of 800 to 1800 m. The ectomycorrhizal fungal (EMF) communities of those 4 forest types were examined by both underground EMF root tips and terrestrial ectomycorrhizal mushrooms (EM) sporocarps.
Several EMF species belonged to 5 genera Cenococcum, Cortinarius, Lactarius, Russula and Tomentella were shared by 4 EMF communities. Russula, Tomentella and Cortinarius groups were recorded as the dominant in all EMF communities. The ecological niches of EMF communities supported to understand the movement of forest vegetation of pine forest under the effect of climate changes.
Among more than 90 genera recorded from EM sporocarps, Russula group also was recorded as the dominant in all EM sporocarps collection. The another were Amanita and Cortinarius. The initial data of edible possibility, yield and season of ectomycorrhizal mushroom were also recorded and analyzed.
From several EMF trains, Suillus luteus, Rhizopogon boninensis and Scleroderma sinnamariense showed their ability to establish ECM and stimulate the growth rate of host P. kesiya. They could be the potential candidates for EMF germs for reforestation in highland Viet Nam. Some other strains of Suillus and Lyophyllum had intially success for artificial cultivation.
