Fungi with Rhizoctonia ‐like mycelia were isolated from the foliage, stem‐base and roots of ericaceous plants collected from nurseries in Scotland. Isolated fungi were identified as either binucleate Rhizoctonia spp. or Rhizoctonia solani on the basis of hyphal characteristics and nuclear number. The optimum temperature range for growth of binucleate Rhizoctonia spp. and R. solani was 20 and 25 C, resepctively. All isolates tested for pathogenicity caused foliar browning, and webs of mycelial growth were observed on dead and dying foliage. Binucleate Rhizoctonia spp. and R. solani are recorded for the first time on container‐grown ericaceous plants in Scotland.
