The tree rotting fungi, scientifically referred to as xylophagus, are considered as the primary decomposer of trees in the forests as they produce enzymatic chemicals that degenerate the structural integrity and vital components of the trees. They grows on both standing and felled log woods. Studies and research in this field in Bhutan is limited. This study focused on polypores which grows on living, standing trees to provide a baseline dataset and guide to the diversity of the tree rotting fungi and their distribution through determining abundance and important value (IV) in Lengkhar and vicinity forest. For this, systematic line transects were established, and data were collected from plots laid systematically along these transects. The study documented 59 species, which was highly diverse (H=3.24). Among all, Trametes versiclor was the most abundant species (IVI=58.08), followed by Mycena spp. (IVI=32.32). The study recommends that related agencies consider mitigation measures to prevent the spread of these tree rotting fungi in the forests.
