Abstract Nodulosphaeria is a ubiquitous genus that com- the family as a distinct genus. The sexual prises saprobic, endophytic and pathogenic species associated morphs of Nodulosphaeria hirta and N. spectabilis are de- with a wide variety of substrates and has 64 species epithets scribed and illustrated using modern concepts. Two new listed in Index Fungorum. The classification of species in the Nodulosphaeria species are introduced. The phylogenetic re- genus has been a major challenge due to a lack of understand- lationships and taxonomy of the genus Nodulosphaeria are ing of the importance of characters used to distinguish taxa, as discussed, but further sampling with fresh collections, refer- well as the lack of reference strains. The present study clarifies ence or ex-type strains and molecular data are needed to obtain the phylogenetic placement of the genus and related species, a better and natural classification for the genus. using fresh collections from Italy.
