Abstract
Four new species and one variety are added to the form-genus Rhizoctonia from the study of over 60 isolates obtained from forest nurseries in Saskatchewan and Manitoba; these are Rhizoctonia dichotoma, R. endophytica, R. endophytica var. filicata, R. globularis, and R. hiemalis. They are chiefly characterized by chlamydospores in chains produced singly and in sporodochia. The chlamydospore characters were consistent within the species, and are therefore considered of dependable diagnostic value. The sporodochia, however, exhibited considerable variability in character and size depending largely on the substrate, and are of little use for taxonomic purposes.Keywords
