Morpho-molecular characterization of sp. nov. and a new host record for .

Collections of fungal samples from two dead leaf specimens from Italy were subjected to morphological examination and phylogenetic analyses. Two coelomycetous taxa belonging to two different genera in Xylariomycetidae, Sordariomycetes, namely and , were identified. The taxon is revealed as a new species and is herein introduced as while the taxon is identified as . Multi-locus phylogeny based on DNA sequence data of the large subunit (LSU) and internal transcribed spacer (ITS) of nuclear ribosomal genes, β-tubulin () and RNA polymerase II second largest subunit () showed that is related to but it forms an independent lineage that supports its new species status. The new taxon also differs from other species by its unilocular to bilocular, superficial and applanate conidiomata with basal stroma composed of cells of , elongate-ampulliform conidiogenous cells and conidia smaller in size. is here reported as a new host record from from Italy. Descriptions, illustrations and molecular data for both species are provided in this paper.
