A fungal species with bitunicate asci and ellipsoid to fusiform ascospores was collected from a dead branch of Rhamnus alpinus in Italy. The new taxon morphologically resembles Leptosphaeria. Maximum likelihood (ML) and Bayesian analyses of a combined LSU and ITS sequence data set confirm its placement in Leptosphaeria sensu stricto. The new taxon is distinct from other species based on morphology and phylogeny and is thus introduced as a new species, viz . L. italica .The new species is compared with other Leptosphaeria species and a comprehensive description and micrographs are provided.
