“…A few species once in Cucurbitaria have recently been identified as belonging to different genera, e.g., Cucurbitaria bicolor , which is a synonym of Thyronectria rhodochlora in the Nectriaceae , Hypocreales ( Checa et al. 2015 ), while Cucurbitaria obducens , C. piceae and C. rhododendri belong to the Melanommataceae ( Jaklitsch & Voglmayr 2017 ).…”

Fresh collections, type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, rpb2, tef1 and tub2 sequences were used to evaluate the boundaries of Cucurbitaria in a strict sense and of several related genera of the Cucurbitariaceae. Two species are recognised in Cucurbitaria and 19 in Neocucurbitaria. The monotypic genera Astragalicola, Cucitella, Parafenestella, Protofenestella, and Seltsamia are described as new. Fenestella is here included as its generic type F. fenestrata (= F. princeps), which is lecto- and epitypified. Fenestella mackenzei and F. ostryae are combined in Parafenestella. Asexual morphs of Cucurbitariaceae, where known, are all pyrenochaeta- or phoma-like. Comparison of the phylogenetic analyses of the ITS-LSU and combined matrices demonstrate that at least rpb2 sequences should be added whenever possible to improve phylogenetic resolution of the tree backbone; in addition, the tef1 introns should be added as well to improve delimitation of closely related species.

“…Besides Thyronectria (Jaklitsch and Voglmayr, 2014, Checa et al., 2015), Thyridaria is another genus that Saccardo derived and separated from Thyridium . In order to clarify the concept of the genus, the identity and history of its generic type has to be evaluated: Cucurbitaria broussonetiae was described by Saccardo (1873).…”

A multigene analysis of a combined ITS-LSU-SSU-rpb2-tef1 sequence data matrix was applied to infer the phylogenetic position of the genus Thyridaria in the Pleosporales. The generic type of Thyridaria, T. broussonetiae (syn. T. incrustans), is situated in a clade currently named Roussoellaceae, which becomes a synonym of Thyridariaceae. However, Thyridaria rubronotata does not belong to this clade, but is here recognised as Cyclothyriella rubronotata in its own family Cyclothyriellaceae. The Thyridariaceae contain the genera Thyridaria, Roussoella, Roussoellopsis, Neoroussoella and the new genus Parathyridaria. Roussoella acaciae is combined in Thyridaria and Roussoella percutaenea in Parathyridaria. Ohleria modesta and an additional new thyridaria-like genus, Hobus, are found to represent isolated lineages with unresolved phylogenetic affinites within the Pleosporales. For Ohleria the new family Ohleriaceae is established. Melanomma fuscidulum belongs to Nigrograna, and three new species are described in this genus. A strain named Biatriospora marina clusters with Nigrograna. Based on the newly recognised species in Nigrograna, morphology and ecology do in no way correlate among these genera, therefore we erect the new family Nigrogranaceae for Nigrograna and recommend to discontinue the use of the family name Biatriosporaceae until fresh material of B. marina becomes available for sequencing.

“…This once again demonstrates that in the Mediterranean, the species diversity of corticolous ascomycetes is very incompletely studied, and that many species still await description (e.g. Voglmayr and Jaklitsch 2011;Voglmayr 2011, 2014;Voglmayr et al 2016;Jaklitsch et al , 2015Jaklitsch et al , 2018aGalán et al 2015;Checa et al 2015). Considering that the Mediterranean is amongst the main biodiversity hotspots of the world (Myers et al 2000), additional species of Stigmatodiscus are likely to be detected in this species-rich area.…”

During a survey on corticolous Dothideomycetes in Mallorca, several collections with ascomata, asci, and ascospores matching the genus Stigmatodiscus (Stigmatodiscales, Dothideomycetes) were revealed, which did not fit any described species. Therefore, these collections were cultured and sequenced, and a multigene matrix of four loci (nuc18S-ITS-28S rDNA, rpb2, tef1 and tub2) was produced. Based on the results of the phylogenetic analyses of this matrix and of morphological investigations, three new species (Stigmatodiscus labiatus, S. oculatus, and S. pinicola) are described and illustrated, Asterodiscus is synonymised with Stigmatodiscus and the new combination S. tamaricis is proposed. A key to all currently known species of Stigmatodiscus is provided.
