Traditionally two families are recognised within this order: <i>Phyllachoraceae</i> and <i>Phaeochoraceae</i>, based mostly on morphological and host characteristics. Currently, the position of the order within the class <i>Sordariomycetes</i> is inconclusive, as well as the monophyly of the order, and its internal phylogenetic structure. Here we present a phylogeny of the order <i>Phyllachorales</i> based on sequence data of 29 species with a broad host range resulting from a wide geographical sampling. We inferred Maximum Likelihood and Bayesian phylogenies from data of five DNA regions: nrLSU rDNA, nrSSU rDNA, ITS rDNA, and the protein coding genes <i>RPB2</i>, and <i>TEF1</i>. We found that the order <i>Phyllachorales</i> is monophyletic and related to members of the subclass <i>Sordariomycetidae</i> within <i>Sordariomycetes</i>. Within the order, members of the family <i>Phaeochoraceae</i> form a monophyletic group, and the family <i>Phyllachoraceae</i> is split into two lineages. Maximum Likelihood ancestral state reconstructions indicate that the ancestor of <i>Phyllachorales</i> had a monocotyledonous host plant, immersed perithecia, and a black stroma. Alternative states of these characters evolved multiple times independently within the order. Based on our results we redefine the family <i>Phyllachoraceae</i> and propose the new family <i>Telimenaceae</i> with <i>Telimena erythrinae</i> as type species, resulting in three families in the order. Species of <i>Telimena</i> spp. occur in several monocotyledonous and eudicotyledonous host plants except <i>Poaceae</i>, and generally have enlarged black pseudostroma around the perithecia, a character not present in species of <i>Phyllachoraceae</i>.</p>","PeriodicalId":20014,"journal":{"name":"Persoonia","volume":"39 ","pages":"74-90"},"PeriodicalIF":9.1,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/77/52/per-39-74.PMC5832958.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35882275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we explored the occurrence, diversity and pathogenicity of <i>Colletotrichum</i> spp. associated with <i>Citrus</i> and allied genera in European orchards, nurseries and gardens. Surveys were carried out during 2015 and 2016 in Greece, Italy, Malta, Portugal and Spain.

During the years of 2014-2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 116 genera, while 23.5 % were not identified to species level. Among these species, 85.8 % (211 species) belonged to <i>Ascomycota</i>; 7.3 % (18 species) belonged to <i>Basidiomycota</i>; 6.9 % (17 species) belonged to <i>Mucoromycotina</i>. The majority of these species have been previously known from other environments, mostly from plants or animals as pathogens, endophytes or via a mycorrhizal association. We also found that 59 % of these species were discovered for the first time from Karst caves, including 20 new species that are described in this paper. The phylogenetic tree based on LSU sequences revealed 20 new species were distributed in six different orders.

Recent molecular studies have shown high levels of morphological homoplasy within the genus.

Here we sequenced and phylogenetically analysed a large set of pan-European and North American collections taxonomically studied and placed in <i>Cortinarius</i> sect. <i>Bicolores</i> and sect. <i>Saturnini</i>, according to traditional morpho-anatomical criteria. Our goal was to circumscribe the evolutionary boundaries of the two sections, to stabilize both the limits and nomenclature of relevant species, and to identify described taxa which, according to our current understanding, belong to other lineages. Our analysis resolves two clades: /Bicolores, including 12 species, one of which is new to science, and /Saturnini, including 6 species. Fifteen binomials, traditionally treated in these two sections based on morphology, do not belong to the above two phylogenetic clades.

A multi-locus phylogeny based on ITS, <i>TEF1-α</i> and <i>TUB2</i>, in conjunction with morphological characters, host associations, and ecological data was employed for species delimitation in <i>Nigrospora</i>, as well as identification of 165 recently collected isolates from China, and three from Europe.
