Premilcurensis senecionis gen. et and sp. nov. was collected on stems of Senecio sp. from Forlì-Cesena Province, Italy andis introduced in Phaeosphaeriaceae with the support of a unique combination of morphological characters and combinedgene phylogenetic analyses. Premilcurensis is distinguished from other genera in Phaeosphaeriaceae in having fusiformto cylindrical, hyaline to yellow-green ascospores with 3–5 septa, and mucilaginous, wing-like appendages at the centralseptum. Phylogenies analyses show Premilcurensis as a distinct lineage from other genera in the family Phaeosphaeriaceaewith high bootstrap support. A comprehensive description and micrographs of P. senecionis is provided and the new genusis compared with morphologically similar taxa.
