Studies of Rosellinia necatrix Perithecia Found in Nature on Avocado Roots

Ascomata of Rosellinia necatrix were found on roots of a dead avocado tree, documenting the occurence of the sexual stage in a commercial field in southern Spain, and a description of the teleomorph was done. Additionally, the Dematophora state was obtained by inoculating avocado plants with germinating ascospores from these perithecia, connecting the anamorph and teleomorph phases of this species and confirming the infection capacity of the mycelium from these ascospores.
