Twenty-seven plant species representing 26 genera were inoculated with Rhizoctonia solani anastomosis group 3 (AG-3). Characteristic stem lesions were observed on potato (Solanum tuberosum) and necrotic roots were observed on hairgrass (Deschampsia beringensis). A superficial discoloration was observed on the roots and crowns of several other species. Dark hyphae and sclerotia were observed on the crowns and roots of most species, indicating an epiphytic but not a pathogenic interaction.
