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.
Waitea circinata was originally described from Australia in 1962, where it was found growing on the undersides of clods of earth in a wheat field. The new genus Waitea, named after the Waite Agricultural Research Institute in Adelaide, was created to accommodate the species. Because of its morphological similarity to species of Rhizoctonia and Thanatephorus, Waitea circinata was presumed to belong within the Ceratobasidiaceae, but cladistic analysis of DNA sequences has shown that it actually belongs in the Corticiaceae and is close to species of Laetisaria (which are also grass pathogens).
