Studies on the virus diseases of Laccaria laccata, L. amethystina and Cantharellus infundibuliformis have been carried out. Further details on the ecology of these diseases and morphology of pathological anomalies have been given. The experimental infection method is also described. Observations using an electron microscope demonstrate that virions with globular virus particles are present in the microcephalic sporophores of Laccaria laccata. Microcephaly has been found in both of the other two fungi. Virion size has been shown to be 28 nm. Further, we have discussed some phenomena of a different type which might be of virus origin, both in the species of fungi studied here and in two other species, Cantharellus cibarius and Armillaria mellea.
