N2 - Wood-decay fungi are one of the major threats to the old and valuable trees in Hong Kong and constitute a main conservation and management challenge because they inhabit dead wood as well as living trees. The diversity, abundance, and distribution of wood-decay fungi associated with standing trees and stumps in four different parks of Hong Kong, including Hong Kong Park, Hong Kong Zoological and Botanical Garden, Kowloon Park, and Hong Kong Observatory Grounds, were investigated. Around 4430 trees were examined, and 52 fungal samples were obtained from 44 trees. Twenty-eight species were identified from the samples and grouped into twelve families and eight orders. Phellinus noxius, Ganoderma gibbosum, and Auricularia polytricha were the most abundant species and occurred in three of the four parks. Most of the species were detected on old trees, indicating that older trees were more susceptible to wood-decay fungi than younger ones. More wood-decay fungal species were observed on Ficus microcarpa trees than on other tree species. These findings expanded the knowledge of wood-decay fungi in urban environments in Hong Kong and provided useful information for the conservation of old trees and the protection of human life and property from the danger of falling trees.
