Ceratobasidium cornigerum is a species of fungus in the order Cantharellales. Basidiocarps (fruit bodies) are thin, spread on the substrate out like a film (effused) and web-like. An anamorphic state is frequently obtained when isolates are cultured. Ceratobasidium cornigerum is saprotrophic, but is also a facultative plant pathogen, causing a number of economically important crop diseases, and an orchid endomycorrhizal associate. The species is genetically diverse and is sometimes treated as a complex of closely related taxa. DNA research shows the species (or species complex) actually belongs within the genus Rhizoctonia.
