Abstract/Contents: | "Members of the form-genus Rhizoctonia are common foliar parasites of cool season turfgrass species. Infected turfgrasses often exhibit foliar lesions, and abundant aerial mycelium may grow from chlorotic and necrotic leaves. Hyphae of Rhizoctonia spp. Can [can] be viewed on hand-cut sections of leaves or leaf sheaths at magnifications of 200-400'. The hyphae are seldom pigmented which helps to distinguish them from hyphae of hyphomydcetes and related fungi. Observation of Rhizoctonia hyphae is aided by staining with either trypan blue or acid fuchisin in lactophenol. All Rhizoctonia spp. Form [form] a characteristic restriction of the cell wall at the origin of hyphal branches. In addition, septa are formed in hyphal branches and in the originating hyphae near the origin of the branches. Infection cushions and appressoria may be observed on leaves or leaf sheaths, but the abundance of these features appears to be influenced by host species and the strain or species of pathogen." |
