A complex double‐stranded RNA (dsRNA) pattern found in mycelial cultures of diseased basidiocarps comprised nine major segments between 0.78–3.6 kbp and four minor segments between 8.8–15 kbp. With extensive subculturing, a new pattern of five segments between 1.5–8.8 kbp was detected in cultures expressing the diseased phenotype. Loss of the 1.5 and 3.6 kbp segments following heat therapy at 30°C was associated with remission of symptoms. Some of the dsRNAs co‐purified with mitochondria in extracts from diseased cultures and basidiocarps.
