Abstract:

We investigated the fungal associates of Rhododendron argyrophyllum and R. floribundum in Sichuan Province. A total of 41 fungal taxa were identified from hair roots based on ITS sequence analyses belonging to the following orders: Helotiales, Eurotiales, Pezizales, and Pleosporales in Ascomycetes, Sebacinales and Agaricales, Erythrobasidiales, and Filobasidiales in Basidiomycetes. Fungal diversity was rich, including ericoid mycorrhizal (ERM), ectomycorrhizal (ECM) and other root-associated fungi. Sebacinales and Helotiales occupied a high proportion of total fungal samples.

Key words: ericoid mycorrhizal fungi, fungal diversity, ITS, Rhododendron
