Waitea circinata
（重定向自Rhizoctonia zeae）
Waitea circinata is a species of fungus in the family Corticiaceae. Basidiocarps (fruit bodies) are thin, effused, and web-like, but the fungus is more frequently encountered in its similar but sterile anamorphic state, sometimes called Rhizoctonia zeae. Waitea circinata is best known as a plant pathogen, causing commercially significant damage to cereal crops and turf grass.
