TL;DR: In this article, the authors present the present status of our knowledge of ecology and pathology of rhizoctonia solani, especially of anastomosis groups or in-traspecific groups.
Abstract: Rhizoctonia solani Kuhn and other Rhizoctonia spp. are widespread in the world and in both cultivated and noncultivated soils. Rhizoctonia spp. are readily isolated from diseased plants and soils, with isolates differing in pathogenicity and morphology, as well as cultural and physiological charac teristics. Based on these differences, many species and intraspecific groups (ISGs) have been described; however, identification of species and ISGs is sometimes very difficult, owing to the absence of the authentic cultures, which hinders mycological and pathological studies. Fortunately, this situa tion has been put in order through the efforts of many researchers through characterization of the genus Rhizoctonia, the species R. solani, and other Rhizoctonia spp. The introduction of the concept of anastomosis groups (AGs) or intraspecific groups, as this paper introduces, has also aided species and subspecies identification. Ecologically, Rhizoctonia spp. are diversified; they may be pathogens on many hosts, saprophytes in soils, or mycorrhizae of orchidiaceous plants. This paper outlines the present status of our knowledge of ecology and pathology of Rhizoctonia solani, especially of anastomosis groups or in traspecific groups.

TL;DR: Hypha! interactions between either Trichoderma harzianum or T. hamawm, and Sclerotium rolfsii or Rhizoctonia so/ani were observed by scanning electron microscopy, and Lysed sites and penetration holes were found in hypha! of the plant pathogenic fungi, following reinoval of parasitic hyphae.
Abstract: Elad, Y., Chet, 1., Boyle, P., and Henis, Y. 1983. Parasitism of Trichoderma spp. on Rhizoctonia so/ani and Sclerotium rolfsii- Scanning e lectron microscopy and nuorescence microscopy. Phytopathology 73:85-88. Hypha! interactions between either Trichoderma harzianum or T. hamawm, and Sclerotium rolfsii or Rhizoctonia so/ani were observed by scanning electron microscopy. Trichoderma spp. auached to the host either by hypha! coils, hooks, or appressoria. Lysed sites and penetration holes were found in hyphae of the plant pathogenic fungi, following reinoval of parasitic hyphae. High 13-(1 ,3) glucanase and chitinase activities were detected in dual agar cultures when 1: harzianum parasitized S. rolfsii,
