Clavicorona is a fungal genus in the family Clavariaceae. The genus was circumscribed by Maxwell Stanford Doty in 1947, who included the species C. pyxidata, C. cristata, C. taxophila, and C. candelabrum. E.J.H.Corner added another five species in 1950: C. candelabrum, C. colensoi, C. javanica, C. mairei, and C. tuba. He included C. dichotoma in 1970.
