Abstract

During a study on the species of Botryosphaeriaceae associated with oak decline in Tunisia, a large collection of Diplodia strains were isolated from Quercus affares, Q. canariensis and Q. suber trees showing a progressive dieback of shoots and branches, trunk canker and exudates and collar rot. Most of the isolates were identified as Diplodia corticola, while two isolates morphologically and phylogenetically (ITS and tef1-alpha sequences data) distinct from all other known species of Diplodia are described here as Diplodia quercivora sp. nov. In artificial inoculation experiments, D. quercivora proved to be pathogenic on three Mediterranean oak species causing necrotic lesions on bark and wood tissues. In particular, among the oak species tested, pubescent oak was the most susceptible. In addition, phylogenetic analyses showed for the first time the existence of two distinct lineages inside D. corticola population.
