Rhizoctonia solani does not produce spores and is hence identified only from mycelial characteristics or DNA analysis. Its hyphal cells are multinucleate. It produces white to deep brown mycelium when grown on artificial medium. The hyphae are 4–15 μm wide and tend to branch at right angles. A septum near each hyphal branch and a slight constriction at the branch are diagnostic. R. solani is subdivided into anastomosis groups (AG) based on hyphal fusion between compatible strains.
The teleomorph of R. solani is Thanatephorus cucumeris. It forms club-shaped basidia with four apical sterigmata on which oval, hyaline basidiospores are borne.
