Most of these are forest trees, such as Acacia, Alnus, Eucalyptus, Populous, Quercus and others. Biscogniauxia species have been reported as endophytic fungi or secondary invaders that attack only stressed plants. During a survey in Rosaceae orchards in southern Italy, several charcoal cankers were observed and carpophore samples were collected. A collection of 31 Biscogniauxia isolates were analysed. Their phylogenetic relationships were determined through study of ITS, ?-tubulin and actin gene sequences. Combining morphological, culture and molecular data, a new species of Biscogniauxia genus is described here as B. rosacearum. This new species is isolated for the first time from Rosaceae hosts in Apulia. The pathogenicity tests show that it causes symptoms on vegetation growth of stems when artificially inoculated, and produces carpophores on the bark surface. } }
