The present study was undertaken to investigate the fungal associates of Rhododendron campanulatum D. Don from Churdhar region of District Shimla and Sirmaur in Himachal Pradesh. Studies revealed the presence of seven species of fungi belonging to six genera (Absidia, Aspergillus, Curvularia, Fusarium, Pythium and Trichoderma) from mycorrhizosphere soil of Rhododendron campanulatum. Fusarium was the most dominant genus among rhizosphere soil fungi. Twenty seven species of AM fungal spores belonging to eight genera (Acaulospora, Dentiscutata, Endogone, Entrophospora, Gigaspora, Glomus, Sclerocystis and Scutellospora) were isolated from the rhizosphere soil of Rhododendron campanulatum. Glomus was the most abundant genus recorded. Twenty species of endophytic fungi belonging to thirteen genera (Alternaria, Aspergillus, Baratalinia, Cephalosporium, Cunninghamella, Fusarium, Gliocladium, Macrophomina, Myrothecium, Penicillium, Phoma, Pythium and Trichoderma) were isolated from the leaves, bark, stem and roots of Rhododendron campanulatum. Penicillium was the most dominant genus among the endophytic fungi. Maximum numbers of endophytic and rhizospheric fungi were observed during the rainy season followed by summer and winter season. Maximum numbers of VAM spores were observed during the rainy season followed by winter and summer season.
