“…multiple appendages in lineages ii and v; appendages absent in lineages i and iv). Previous generic circumscriptions of these coelomycetes based on conidial appendages alone are not well supported, a finding which was also recently observed among other genera of appendaged coelomycetes (Barber et al 2011, Crous et al 2012). The type species of Kellermania , K. yuccigena , and Piptarthron , P. macrosporum ( ≡ K. macrospora ), belong to separate lineages ii and i, respectively, that notably form a clade (pp = 0.89) with K. unilocularis in the ITS analysis (Fig.…”

Phylogeny and taxonomic revision of the Planistromellaceae including its coelomycetous anamorphs: contributions towards a monograph of the genus Kellermania

et al. 2012

View full text Add to dashboard Cite

The core species of the family Planistromellaceae are included in the teleomorphic genera Planistroma and Planistromella and the connected anamorphic, coelomycetous genera Alpakesa, Kellermania, and Piptarthron. These genera have been defined primarily on the basis of ascospore septation or number of conidial appendages. Due to a lack of DNA sequence data, phylogenetic placement of these genera within the Dothideomycetes, evaluation of monophyly, and questions about generic boundaries could not be adequately addressed in the past. Isolates of nearly all of the known species in these genera were studied genetically and morphologically. DNA sequence data were generated for the nSSU, ITS, nLSU, and RPB1 markers and analysed phylogenetically. These results placed the Planistromellaceae, herein recognised as a distinct family, in an unresolved position relative to other genera within the order Botryosphaeriales. Species representing the core genera of the Planistromellaceae formed a clade and evaluation of its topology revealed that previous morphology-based definitions of genera resulted in an artificial classification system. Alpakesa, Kellermania, Piptarthron, Planistroma, and Planistromella are herein recognised as belonging to the single genus Kellermania. The following new combinations are proposed: Kellermania crassispora, K. dasylirionis, K. macrospora, K. plurilocularis, and K. unilocularis. Five new species are described, namely K. con- fusa, K. dasylirionicola, K. micranthae, K. ramaleyae, and K. rostratae. Descriptions of species in vitro and a key to species known from culture are provided.

“…with Discostroma sexual morphs. Barber et al (2011) and Tanaka et al (2011) also showed that both Seimatosporium and Discostroma cluster in a monophyletic clade in their molecular data analyses. However, both genera lack molecular data for their type species (Tanaka et al 2011), thus we prefer to maintain both names until the link is proven by molecular analyses.…”

“…Swart have long, falcate, fusiform or sigmoid conidia with 3-4-septa, rarely 5-septa, and basal appendages. These species were excluded from Seimatosporium and included in Vermisporium based on their morphology and phylogeny (Barber et al 2011). Therefore we introduce Seimatosporium rhombisporum as a new species considering both morphology and phylogeny.…”

The classification of subclass Xylariomycetidae is revisited with additional collections and phylogeny based on novel rDNA sequence data. Phylogenetic inferences are provided and are based on analysis of 115 sequence data, including new data for 27 strains. An updated outline to the subclass is presented based on the phylogenies and comprises two orders, 18 families and 222 genera. An account of each order, family and genus in the subclass is given. We accept the orders Amphisphaeriales and Xylariales based on morphological and phylogenetic evidence. Amphisphaeriales comprises Amphisphaeriaceae, Bartaliniaceae fam. nov., Clypeosphaeriaceae, Discosiaceae f a m . n o v. , P e s t a l o t i o p s i d a c e a e f a m . n o v. a n d Phlogicylindriaceae fam. nov. Xylariales comprises Apiosporaceae, Cainiaceae, Coniocessiaceae, Diatrypaceae, Graphostromataceae (doubtful), Hyponectriaceae, Iodosphaeriaceae, Lopadostomaceae fam. nov., Melogrammataceae, Pseudomassariaceae fam. nov., Vialaeaceae and Xylariaceae. The new genera and species introduced are Arthrinium hyphopodii, A. subglobosa,

LSU sequence data reveal that Truncatella is a distinct genus in the family Amphisphaeriaceae (Jeewon et al 2002;Barber et al 2011;Maharachchikumbura et al 2014). …”

“…Vermisporium was chiefly distinguished from Seimatosporium on the basis of a short exogenous basal appendage, and the absence of a recognisable apical appendage. Barber et al (2011) showed the genus to be a synonym of Seimatosporium based on DNA sequence data analysis of the nrDNA-ITS and 28S nrRNA genes, and transferred eight species to Seimatosporium.…”

Towards a natural classification and backbone tree for Sordariomycetes

et al. 2015

View full text Add to dashboard Cite

Sordariomycetes is one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, and fungicolous, lichenized or lichenicolous taxa. The class includes freshwater, marine and terrestrial taxa and has a worldwide distribution. This paper provides an updated outline of the Sordariomycetes and a backbone tree incorporating asexual and sexual genera in the class. Based on phylogeny and morphology we introduced three subclasses; D i a p o r t h o m y c e t i d a e , L u l w o r t h i o m y c e t i d a e a n dTogniniales. The outline is based on literature to the end of 2014 and the backbone tree published in this paper. Notes for 397 taxa with information, such as new family and genera novelties, novel molecular data published since the Outline of Ascomycota 2009, and new links between sexual and asexual genera and thus synonymies, are provided. The Sordariomycetes now comprises six subclasses, 28 orders, 90 families and 1344 genera. In addition a list of 829 genera with uncertain placement in Sordariomycetes is also provided.
