First records of Ganoderma suae and Pleurotus tuber regium in Vietnam

Two medicinal mushroom species, Pleurotus tuber-regium (Lentinus tuber-regium) (commonly known as the sclerotium-forming oyster mushroom) and Ganoderma suae (a resinous polypore recently described from Southeast China in 2024)—are reported for the first time in Vietnam. The taxonomic histories of both genera, Ganoderma and Pleurotus are complex due to morphologically similarities among closely related species, posing challenges for accurate identification. In this study, specimens collected from National resources of Vietnam were identified combining detailed morphological examination with molecular analysis using rDNA ITS markers for phylogenetic confirmation. This report enhances the understanding of fungal diversity in Vietnam and provides a basis for further studies on cultivation, bioactivity, and value-added applications.
