“…3). Both the family Pleosporaceae and Melanommataceae were grouped into a distinct 100%-bootstrap-supported clade, which was also described by CÂMARA et al (2003) previously. Phaeosphaeriaceae/Leptosphaeriaceae with S. bambusicola and Pleosporaceae seem to be sister groups as supported by 93% bootstrapping though Phaeosphaeriaceae/Leptosphaeriaceae was not well supported (53%).…”

In this study, 18S rDNA and ITS-5.8S rDNA regions of four Shiraia bambusicola isolates collected from different species of bamboos were amplified by PCR with universal primer pairs NS1/NS8 and ITS5/ITS4, respectively, and sequenced. Phylogenetic analyses were conducted on three selected datasets of rDNA sequences. Maximum parsimony, distance and maximum likelihood criteria were used to infer trees. Morphological characteristics were also observed. The positioning of Shiraia in the order Pleosporales was well supported by bootstrap, which agreed with the placement by Amano (1980) according to their morphology. We did not find significant inter-hostal differences among these four isolates from different species of bamboos. From the results of analyses and comparison of their rDNA sequences, we conclude that Shiraia should be classified into Pleosporales as Amano (1980) proposed and suggest that it might be positioned in the family Phaeosphaeriaceae.

“…The genera Paraphoma, Setophoma and Neosetophoma grouped in sister clades closely related to the teleomorph genera Ophiosphaerella, Phaeosphaeria and Phaeosphaeriopsis, mainly recorded on Poaceae. The Phaeosphaeria species included in this study represent ''clade B'' in an 18S rDNA sequence analysis by Câmara et al (2002). The associated anamorphs in this clade are variable and described as ''Stagonospora-like'', ''Coniothyrium-like'', or as Microsphaeropsis sp.…”

“…In molecular studies it was demonstrated that C. berberidis, being the type species of Cucurbitaria, was only distantly related to Herpotrichia juniperi and Herpotrichia diffusa, both species with an unknown anamorph (Berbee 1996, Silva-Hanlin andHanlin 1999). In a subsequent molecular study H. juniperi and H. diffusa were classified in the Melanommataceae (Câmara et al 2003). The basal clustering of H. parasitica with Cucurbitaria berberidis in the Cucurbitariaceae demonstrate that both species with a Pyrenochaeta anamorph are related and that H. parasitica does not fit in genus Herpotrichia.…”

Sequence data from the 18S nrDNA (SSU) and 28S nrDNA (LSU) regions of isolates of Phoma section Paraphoma were compared with those of representative isolates of the morphologically similar anamorph genera Pleurophoma and Pyrenochaeta and of the type species of Phoma sections Phoma, Pilosa and Plenodomus. Phoma section Paraphoma was found to be highly polyphyletic within the Pleosporales and only distantly related to Phoma section Phoma. The genus Paraphoma, which is based on Paraphoma radicina, is reintroduced in the Phaeosphaeriaceae with two additional taxa. The new genera Setophoma and Neosetophoma, type species Setophoma terrestris comb. nov. and Neosetophoma samarorum comb. nov., are introduced and represent species that are closely related to Paraphoma but differ based on morphological characters and molecular phylogeny. Phoma coonsii is transferred to genus Chaetosphaeronema that also belongs to the Phaeosphaeriaceae. Pyrenochaetopsis gen. nov. is introduced to accommodate the type species Pyrenochaetopsis leptospora comb. nov., as well as several other species formerly accommodated in Phoma and Pyrenochaeta. Pyrenochaetopsis is closely related to Pyrenochaeta and classified in the Cucurbitariaceae. Pleurophoma cava is transferred to genus Pyrenochaeta. The new genera elucidate the confusing taxonomy of species in genera Phoma, Pyrenochaeta and Pleurophoma and recognize monophyletic genera with distinct teleomorph affinities.

“…Phaeosphaeriopsis was introduced by Câmara et al (2003) based on morphology and 18S rDNA sequence analysis in order to accommodate four species of Paraphaeosphaeria Phaeosphaeriopsis was characterized by immersed, subepidermal, globose to subglobose to pyriform ascomata, cylindric asci and septate, punctate or verrucose ascospores with Coniothyrium-like or Phaeostagonospora asexual states. Farr et al (2006) examined Sphaeria phacidiomorpha and transferred to Phaeosphaeriopsis phacidiomorpha.…”

A collection of the type species of Phaeosphaeriopsis, P. glaucopunctata, and a new species associated with leaf spots of Ruscus aculeatus were collected in Italy. Single ascospore isolates of both species were obtained and formed asexual morphs in culture. Combined ITS, LSU, SSU and RPB2 gene sequence analysis from taxa in Phaeosphaeriaceae showed that P. glaucopunctata and the new species cluster in Phaeosphaeriaceae, forming a separate clade from other species in the family. In this study, we designate our new collection of P. glaucopunctata as an epitype. The new Phaeosphaeriopsis species is morphologically similar to P. glaucopunctata , but has 3-septate ascospores. A detailed description and illustration is provided for both species and the new taxon is compared with other Phaeosphaeriopsis species. Phaeosphaeriopsis musae is excluded from Phaeosphaeriopsis based on morphology and multigene phylogenetic analysis and synonymized under Phaeosphaeria musae. In present study seven species are accepted in the genus Phaeosphaeriopsis and a key to species is provided.
