“…Taxonomic characterizations of taxa in Torulaceae have been well-studied since Crous et al [8] who re-classified Torula and Dendryphion in Torulaceae (Pleosporales, Dothideomycetes) based on phylogenetic analyses of LSU sequence data. Subsequent authors introduced new genera and species in this family based on multigene phylogenetic analyses coupled with morphological characteristics (see Table 3) [10,18,9,5,6,7,20]. Recently, there are more than 520 epithets in the genus Torula and 85 epithets in Dendryphion listed in Index Fungorum [26].…”

“…Phylogenetic analyses were performed from single gene (LSU dataset) as well as based on a combined LSU, SSU, TEF1-α, RPB2 and ITS sequence dataset. Sequences generated from this study were analyzed with other similar sequences obtained from GenBank and those derived from recent publications [32,10,19,9,5,6,7] (Table 1). The single gene alignment was performed by using MAFFT v. 7 [33] (http://mafft.cbrc.jp/alignment/server/) and manually aligned wherever necessary in MEGA version 7.0 [34].…”

“…Torula and Dendryphion have a wide host range in various habitats and are commonly found as saprobes in both terrestrial and aquatic habitats in temperate to tropical regions [10,3,59,18,9,5,6,7,20]. It is interesting to note that many Torula species have been found to be associated with the host family Asteraceae [59,5].…”

During our studies on asexual fungi colonizing herbaceous litter in northern Thailand, we discovered two new fungal species, viz. Dendryphion hydei and Torula hydei spp. nov. The latter are examined, and their morphological characters are described as well as their DNA sequences from ribosomal and protein coding genes are analysed to infer their phylogenetic relationships with extant fungi. Torula hydei is different from other similar Torula species in having tiny and catenate conidia. Dendryphion hydei can be distinguished from other similar Dendryphion species in having large conidiophores and subhyaline to pale olivaceous brown, 2-4(-5)-septate conidia. Multigene phylogenetic analyses of a combined LSU, SSU, TEF1-α, RPB2 and ITS DNA sequence dataset generated from maximum likelihood and Bayesian inference analyses indicate that T. hydei forms a distinct lineage and basal to T. fici. Dendryphion hydei forms a distinct lineage and basal to D. europaeum, D. comosum, D. aquaticum and D. fluminicola within Torulaceae (Pleosporales, Dothideomycetes).

“…Nowadays, the genus is classified as Pezizomycotina incertae sedis in Index Fungorum (accessed 14 Sep. 2020). However, Crous et al (2019) published sequence data for N. gelatosporum which revealed a phylogenetic affiliation with Cenangiaceae (Leotiomycetes). Also, they decided to place N. spartii in a new genus Pseudomelanconium based on morphological differences, albeit no sequence data were available for the latter.…”

Based on molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, RPB1, RPB2 and TEF1 sequences and by morphological evidence, the genus Mycosphaerangium is shown to be the closest relative of Neomelanconium, and confirmed to be a member of the Cenangiaceae (Leotiomycetes). While Mycosphaerangium and Neomelanconium share many traits like similar conidia, conidiogenesis, asci and ascospores, their apothecia differ particularly in excipular features and are therefore recognized as distinct genera. Mycosphaerangium tiliae, described from North America, is excluded from the genus but shown to represent the sexual morph of the European Neomelanconium gelatosporum, and it is therefore synonymized with the latter. Based on morphology, Neomelanconium deightonii is assumed to be congeneric with Neomelanconium gelatosporum, and it is lectotypified. Dermatea tetraspora and Phaeangium magnisporum, the basionyms of Mycosphaerangium tetrasporum and M. magnisporum, respectively, are lectotypified as well, and for M. tetrasporum, the asexual morph is recorded for the first time. Mycosphaerangium quercinum sp. nov. is described as a new species from various Quercus hosts in Europe, where it is shown to be widely distributed. It morphologically and ecologically closely resembles the North American M. tetrasporum, but differs in paraphysis and ascospore morphology and by croziers at its ascus base. The three accepted species of Mycosphaerangium and the two of Neomelanconium are described and illustrated. Mycosphaerangium magnisporum, M. quercinum and M. tetrasporum are recorded to be constantly associated with species of Coryneum, indicating a fungicolous habit, but no evidence for fungal associations has been found in Neomelanconium deightonii and N. gelatosporum.

Fossils can reveal long-vanished characters that inform inferences about the timing and patterns of diversification of living fungi. Through analyzing well-preserved fossil scutella, shield-like covers of fungal sporocarps, we describe a new taxon of early Dothideomycetes with a combination of characters unknown among extant taxa. METHODS: Macerated clays from the Potomac Group, lower Zone 1, from the Lower Cretaceous (Aptian, 125-113 Ma) of Virginia USA yielded one gymnospermous leaf cuticle colonized by 21 sporocarps of a single fungal morphotype. We inferred a tree from nuclear ribosomal DNA of extant species, and coded morphological characters to evaluate alternative, equally parsimonious placements of the fossil in a molecular constraint tree of extant species. RESULTS: Bleximothyrium ostiolatum gen. et sp. nov. has an ostiolate scutellum of radiate, dichotomizing hyphae. Unlike otherwise similar extant and fossil taxa, B. ostiolatum has tangled hyphae at its scutellum margin. Scutella of B. ostiolatum are connected to superficial mycelium, to intercalary and lateral appressoria, and to extensive subcuticular "mycélium en palmettes". The gymnospermous host has characters consistent with identity as a non-papillate ginkgophyte or cycad. CONCLUSIONS: Bleximothyrium ostiolatum is the oldest known fossil fly-speck fungus that occurs on plant cuticles and has the radiate, ostiolate scutellum known only from Dothideomycetes. Its combination of characters, its scutellum margin, and mycélium en palmettes are unknown in other extant and fossil species, and Bleximothyrium ostiolatum likely represents a new group of fly-speck fungi that may now be extinct.
