New asexual morph taxa in Phaeosphaeriaceae

Species of Phaeosphaeriaceae, especially the asexual taxa, are common plant pathogens that infect many important economic crops. Ten new asexual taxa (Phaeosphaeriaceae) were collected from terrestrial habitats in Italy and are introduced in this paper. In order to establish the phylogenetic placement of these taxa within Phaeosphaeriaceae we analyzed combined ITS and LSU sequence data from the new taxa, together with those from GenBank. Based on morphology and molecular data, Poaceicola gen. nov. is introduced to accommodate the new species Po. arundinis (type species), Po. bromi and Po. elongata. The new species Parastagonospora dactylidis, P. minima, P. italica, P. uniseptata and P. allouniseptata, Septoriella allojunci and Wojnowicia spartii are also introduced with illustrated accounts and compared with similar taxa. We also describe an asexual morph of a Nodulosphaeria species for the first time.
