Ceratobasidium ochroleucum is a species of fungus in the family Ceratobasidiaceae. Basidiocarps are effused and web-like and were originally described from Brazil, causing a thread blight of apple and quince trees. The fungus was subsequently reported as a leaf disease on orchard crops in North America, but since descriptions of Ceratobasidium orchroleucum vary considerably and no type specimen exists, its identity remains unclear. Roberts (1999) considered it a "nomen dubium".

Claviceps zizaniae is a plant pathogen that causes ergot in the wild rice species Zizania aquatica and Z. palustris. Originally described in 1920 as Spermoedia zizaniae by Faith Fyles, it was transferred to Claviceps in 1959 by Maria E. Pantidou. The new combination, however, was not published validly as Pantidou "failed to provide a full and direct reference to the place of publication". The binomial was published validly by Scott Redhead and colleagues in 2009.
