Abstract
Wood-inhabiting fungi are the important components of forest ecosystem and p lay a key function during thewood decomposition. Postia can degrade the cellulose and semicellulose of wood and causes a brown-rot. Thebrown-rot remains are necessary for the coniferous forest renewing by their special functions. In this study, the ecological study on Postia from China was carried out. The results showed that the stages of decomposition of fallen decorticated trunkswere closely related with the distribution of species of Postia, and the quotientwas 0. 885. In addition, species in the genus p referred to coniferouswood rather than deciduouswood, about 86% specieswere foundon coniferous wood. The most suitable coniferous hosts were sp ruces and p ines. The most suitable deciduous hostswere birch and pop lar.
