Ribosomal and Protein Gene Phylogeny Reveals Novel Saprobic Fungal Species FromJuglans regiaandUrtica dioica

During an ongoing investigation of Ascomycetes from plant substrates, three saprobic species were found from plant substrates. Two new species,Leptosphaeria regiaeandNeomicrosphaeropsis juglandiswere isolated from dead branches ofJuglans regiafrom Turkey. Another species is introduced herein asSubplenodomus urticaesp. nov within the family Leptosphaeriaceae found onUrtica dioicain Italy. Multigene phylogenies based on combined LSU, ITS, SSU, and beta-tubulin DNA sequence data generated from maximum likelihood and MrBayes analyses indicate thatLeptosphaeria regiaeis related toL. slovacicaand forms an independent lineage within the genusLeptosphaeria.Subplenodomus urticaeis basal toS. iridicolaand its establishment as a new species is strongly supported.Neomicrosphaeropsis juglandisforms a moderately supported lineage in betweenN. italicaandN. elaeagniin the Didymellaceae. Full morphological details are provided herein and phylogenetic relationships of the three new species are also discussed

Beta-tubulin and Actin gene phylogeny supports Phaeoacremonium ovale as a new species from freshwater habitats in China

A new species of Phaeoacremonium, P. ovale (Togniniaceae), was isolated during a diversity study of freshwater fungi from Yunnan Province in China. Morphological and cultural studies of the fungus were carried out and its sexual and asexual morphs (holomorph) are introduced herein. This species is characterised by peculiar long-necked, semi-immersed ascomata with oval to ellipsoid ascospores and ellipsoid to ovoid conidia. Phylogenetic analyses of a combined TUB and ACT gene dataset revealed that strains of P. ovale constitute a strongly supported independent lineage and are related to P. griseo-olivaceum and P. africanum. The number of nucleotide differences, across the genes analysed, also supports establishment of P. ovale as a new species

Naming and outline of Dothideomycetes-2014 including proposals for the protection or suppression of generic names

Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and nonpleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data

New <i>Arthrobotrys</i> Nematode-Trapping Species (Orbiliaceae) from Terrestrial Soils and Freshwater Sediments in China

Arthrobotrys is the most complex genus of Orbiliaceae nematode-trapping fungi. Its members are widely distributed in various habitats worldwide due to their unique nematode-trapping survival strategies. During a survey of nematophagous fungi in Yunnan Province, China, twelve taxa were isolated from terrestrial soil and freshwater sediment habitats and were identified as six new species in Arthrobotrys based on evidence from morphological and multigene (ITS, TEF, and RPB2) phylogenetic analyses. These new species i.e., Arthrobotrys eryuanensis, A. jinpingensis, A. lanpingensis, A. luquanensis, A. shuifuensis, and A. zhaoyangensis are named in recognition of their places of origin. Morphological descriptions, illustrations, taxonomic notes, and a multilocus phylogenetic analysis are provided for all new taxa. In addition, a key to known species in Arthrobotrys is provided, and the inadequacies in the taxonomic study of nematode-trapping fungi are also discussed
