Genera of phytopathogenic fungi: GOPHY 1

Genera of Phytopathogenic Fungi (GOPHY) is introduced as a new series of publications in order to provide a stable platform for the taxonomy of phytopathogenic fungi. This first paper focuses on 21 genera of phytopathogenic fungi: Bipolaris, Boeremia, Calonectria, Ceratocystis, Cladosporium, Colletotrichum, Coniella, Curvularia, Monilinia, Neofabraea, Neofusicoccum, Pilidium, Pleiochaeta, Plenodomus, Protostegia, Pseudopyricularia, Puccinia, Saccharata, Thyrostroma, Venturia and Wilsonomyces. For each genus, a morphological description and information about its pathology, distribution, hosts and disease symptoms are provided. In addition, this information is linked to primary and secondary DNA barcodes of the presently accepted species, and relevant literature. Moreover, several novelties are introduced, i.e. new genera, species and combinations, and neo-, lecto- and epitypes designated to provide a stable taxonomy. This first paper includes one new genus, 26 new species, ten new combinations, and four typifications of older names.

Taxonomic and phylogenetic re-evaluation of Microdochium, Monographella and Idriella

Based on morphology and DNA sequence data the taxonomic relationships of Microdochium, Monographella and Idriella were reassessed. Microdochium is morphologically and phylogenetically circumscribed, and the sexual genus Monographella treated as synonym on the basis that Microdochium has more species, is more commonly encountered, and more frequently used in literature. An epitype is designated for Microdochium phragmites, and several well-known species are redefined based on their morphology and DNA sequence data (LSU, ITS, BTUB and RPB2). Furthermore, the revision of Microdochium led to six new combinations (M. albescens, M. consociatum, M. fusariisporum, M. maydis, M. opuntiae and M. stevensonii) and six new species (M. citrinidiscum, M. colombiense, M. fisheri, M. neoqueenslandicum, M. seminicola and M. trichocladiopsis) being proposed. Microdochium s.str. belongs to a monophyletic clade, together with Idriella lunata and Selenodriella, representing a new family, Microdochiaceae, in Xylariales. Other species previously accommodated in Microdochium belong to different orders in the Ascomycota. Microdochium gracile belongs to Sordariomycetes (incertae sedis) and Paramicrodochium is proposed to accommodate this species. Microdochium tripsaci belongs to Ephelis in Clavicipitaceae, while M. fusarioides belongs to a new genus, Microdochiella in Orbiliales. Idriella s.str. is a monotypic genus phylogenetically closely related to Microdochium. Idriella s.l. separates into different genera in Xylariales (incertae sedis) including Castanediella, Selenodriella, Idriellopsis, Neoidriella and Paraidriella, the last three proposed here as new genera.

Phylogeny of saprobic microfungi from Southern Europe

During a survey of saprophytic microfungi on decomposing woody, herbaceous debris and soil from different regions in Southern Europe, a wide range of interesting species of asexual ascomycetes were found. Phylogenetic analyses based on partial gene sequences of SSU, LSU and ITS proved that most of these fungi were related to Sordariomycetes and Dothideomycetes and to lesser extent to Leotiomycetes and Eurotiomycetes. Four new monotypic orders with their respective families are proposed here, i.e. Lauriomycetales, Lauriomycetaceae; Parasympodiellales, Parasympodiellaceae; Vermiculariopsiellales, Vermiculariopsiellaceae and Xenospadicoidales, Xenospadicoidaceae. One new order and three families are introduced here to accommodate orphan taxa, viz. Kirschsteiniotheliales, Castanediellaceae, Leptodontidiaceae and Pleomonodictydaceae. Furthermore, Bloxamiaceae is validated. Based on morphology and phylogenetic affinities Diplococcium singulare, Trichocladium opacum and Spadicoides atra are moved to the new genera Paradiplococcium, Pleotrichocladium and Xenospadicoides, respectively. Helicoon fuscosporum is accommodated in the genus Magnohelicospora. Other novel genera include Neoascotaiwania with the type species N. terrestris sp. nov., and N. limnetica comb. nov. previously accommodated in Ascotaiwania; Pleomonodictys with P. descalsii sp. nov. as type species, and P. capensis comb. nov. previously accommodated in Monodictys; Anapleurothecium typified by A. botulisporum sp. nov., a fungus morphologically similar to Pleurothecium but phylogenetically distant; Fuscosclera typified by F. lignicola sp. nov., a meristematic fungus related to Leotiomycetes; Pseudodiplococcium typified by P. ibericum sp. nov. to accommodate an isolate previously identified as Diplococcium pulneyense; Xyladictyochaeta typified with X. lusitanica sp. nov., a foliicolous fungus related to Xylariales and similar to Dictyochaeta, but distinguished by polyphialidic conidiogenous cells produced on setiform conidiophores. Other novel species proposed are Brachysporiella navarrica, Catenulostroma lignicola, Cirrenalia iberica, Conioscypha pleiomorpha, Leptodontidium aureum, Pirozynskiella laurisilvatica, Parasympodiella lauri and Zanclospora iberica. To fix the application of some fungal names, lectotypes and/or epitypes are designated for Magnohelicospora iberica, Sporidesmium trigonellum, Sporidesmium opacum, Sporidesmium asperum, Camposporium aquaticum and Psilonia atra.

New species of Cordana and epitypification of the genus

Two interesting fungi belonging to the genus Cordana have been isolated recently in Spain from plant debris. Both are proposed here as new species, described and illustrated. Cordana mercadiana sp. nov. produces 0–1-septate conidia, with a prominent basal scar. Cordana verruculosa sp. nov. differs from the other species of the genus by its unique combination of aseptate, verruculose and small conidia. Both species are compared morphologically with other species of Cordana and their identities supported by the analysis of rDNA sequences. LSU sequence analysis revealed the congeneric relationship of Cordana and Pseudobotrytis; the members of both genera are in a well supported monophyletic lineage that appears to be related to the Coniochaetales but remains incertae sedis within the Sordariomycetes. To establish nomenclatural stability of the genus Cordana, an isolate of C. pauciseptata is designed here as epitype and the two species of Pseudobotrytis are transferred to Cordana. A dichotomous key is provided to identify the currently accepted species of Cordana.

Take-all or nothing

Take-all disease of Poaceae is caused by Gaeumannomyces graminis (Magnaporthaceae). Four varieties are recognised in G. graminis based on ascospore size, hyphopodial morphology and host preference. The aim of the present study was to clarify boundaries among species and varieties in Gaeumannomyces by combining morphology and multi-locus phylogenetic analyses based on partial gene sequences of ITS, LSU, tef1 and rpb1. Two new genera, Falciphoriella and Gaeumannomycella were subsequently introduced in Magnaporthaceae. The resulting phylogeny revealed several cryptic species previously overlooked within Gaeumannomyces. Isolates of Gaeumannomyces were distributed in four main clades, from which 19 species could be delimited, 12 of which were new to science. Our results show that the former varieties Gaeumannomyces graminis var. avenae and Gaeumannomyces graminis var. tritici represent species phylogenetically distinct from G. graminis, for which the new combinations G. avenae and G. tritici are introduced. Based on molecular data, morphology and host preferences, Gaeumannomyces graminis var. maydis is proposed as a synonym of G. radicicola. Furthermore, an epitype for Gaeumannomyces graminis var. avenae was designated to help stabilise the application of that name.

New Bactrodesmiastrum and Bactrodesmium from decaying wood in Spain

Several new species belonging to the anamorph genera Bactrodesmiastrum and Bactrodesmium, collected from plant debris in Spain, are described and illustrated. Bactrodesmiastrum pyriforme, sp. nov. is characterized by large, pyriform conidia. Bactrodesmiastrum obovatum comb. nov. is proposed to accommodate janetia obovata, and the Spanish specimen of B. obscurum. the type species of the genus, represents the second known collection of the species worldwide. Analyses of rDNA sequences confirm the distinction between B. obovatum and B. pyriforme, and reveal their relationships with the Savoryellales (Sordariomycetes). Bactrodesmium diver-sum sp. nov. is distinguished from the other species of the genus by its large, pale brown conidia with a conspicuous pore at each septum.
