Tubeufiaceae is based on the generic type Tubeufia, which is characterized by superficial, oval and bright ascomata, bitunicate asci, mostly long fusiform to filiform, transeptate ascospores and hyphomycetous asexual states with helicosporous conidia. Most species in this family are saprobic on terrestrial woody substrates and some are aquatic. Their distinct morphology as well as combined LSU, SSU and TEF1 sequence analysis show that Tubeufiaceae should be accommodated in a new order Tubeufiales, which is introduced in this paper. Phylogenetic analyses of combined LSU and ITS sequences were used to resolve genera and species within the family Tubeufiaceae. In this study, we examine and incorporate sexual and asexual states of genera in Tubeufiales to provide a modern treatment, based on single names. An epitype for Tubeufia javanica, the type species of Tubeufia, is designated and represents Tubeufia sensu stricto. The genera Acanthophiobolus, Acanthostigma, Boerlagiomyces, Chlamydotubeufia, Kamalomyces, Podonectria, Thaxteriella and Thaxteriellopsis are accepted, Acanthostigmina is reinstated, and the asexual genera Aquaphila, Helicoma, Helicomyces, Helicosporium and Tamhinispora are accepted in Tubeufiaceae. Three new genera Acanthohelicospora, Helicangiospora and Neoacanthostigma are introduced. The genus Bifrontia is added to the family based on morphological similarity. The incongruous morphological genera Acanthostigmella, Amphinectria, Chaetocrea, Chaetosphaerulina, Glaxoa, Malacaria, Melioliphila, Paranectriella, Puttemansia, Rebentischia and Uredinophila are excluded from Tubeufiaceae despite having characteristic ascomata with setae and multiseptate long spores. A key to genera accepted in Tubeufiaceae is provided. © 2014, School of Science.

A fungal species with bitunicate asci and ellipsoid to fusiform ascospores was collected from a dead branch of Rhamnus alpinus in Italy. The new taxon morphologically resembles Leptosphaeria. Maximum likelihood (ML) and Bayesian analyses of a combined LSU and ITS sequence dataset confirm its placement in Leptosphaeria sensu stricto. The new taxon is distinct from other species based on morphology and phylogeny and is thus introduced as a new species, viz. L. italica. The new species is compared with other Leptosphaeria species and a comprehensive description and micrographs are provided. Copyright. © 2015.

The generic types of four genera with unclear placement in Dothideomycetes were re-examined. These genera were hitherto poorly illustrated or described. The type specimens of Cocconia (C. palmae), Dianesea (D. palmae), Endococcus (E. rugulosus) and Lineostroma (L. banksiae), were re-examined in order to determine their familial and higher level placements, according to their morphology and based on modern taxonomic concepts. A resume of the history along with descriptions and illustrations of these genera are provided. Endococcus and Lineostroma are placed in families Lichenotheliaceae and Didymosphaeriaceae, respectively, based on morphology. The placement of Cocconia within Parmulariaceae is confirmed. Dianesea is retained in Dothideomycetes genera incertae sedis as it is not typical of any existing family of Dothideomycetes. Fresh collections of these genera are needed for further study, so that they can be epitypified and molecular data is needed to validate their phylogeny and natural classification. © 2016 Magnolia Press.

The family Anteagloniaceae comprises the genera, Anteaglonium and Flammeascoma. The family shares similar characters with taxa in the Hysteriales, but groups in the Pleosporales. No asexual morph is known in this family. In the present study we introduce a new species Anteaglonium thailandicum, re-examine A. parvulum and document its asexual morph. We observed different culture characters with similar morphology and molecular data for four strains of A. parvulum isolated from collections in Thailand. In this study we introduce A. thailandicum which has different hysterothecial characters as compared to A. parvulum and A. globosum, especially in the globose, roughened wall, indistinct slit, short subicula and short tomentum and also based on differences in LSU, SSU and TEF sequence data. © 2016 Magnolia Press.

Taxonomic names are key links between various databases that store information on different organisms. Several global fungal nomenclural and taxonomic databases (notably Index Fungorum, Species Fungorum and MycoBank) can be sourced to find taxonomic details about fungi, while DNA sequence data can be sourced from NCBI, EBI and UNITE databases. Although the sequence data may be linked to a name, the quality of the metadata is variable and generally there is no corresponding link to images, descriptions or herbarium material. There is generally no way to establish the accuracy of the names in these genomic databases, other than whether the submission is from a reputable source. To tackle this problem, a new database (FacesofFungi), accessible at www.facesoffungi.org (FoF) has been established. This fungal database allows deposition of taxonomic data, phenotypic details and other useful data, which will enhance our current taxonomic understanding and ultimately enable mycologists to gain better and updated insights into the current fungal classification system. In addition, the database will also allow access to comprehensive metadata including descriptions of voucher and type specimens. This database is user-friendly, providing links and easy access between taxonomic ranks, with the classification system based primarily on molecular data (from the literature and via updated web-based phylogenetic trees), and to a lesser extent on morphological data when molecular data are unavailable. In FoF species are not only linked to the closest phylogenetic representatives, but also relevant data is provided, wherever available, on various applied aspects, such as ecological, industrial, quarantine and chemical uses. The data include the three main fungal groups (Ascomycota, Basidiomycota, Basal fungi) and fungus-like organisms. The FoF webpage is an output funded by the Mushroom Research Foundation which is an NGO with seven directors with mycological expertise. The webpage has 76 curators, and with the help of these specialists, FoF will provide an updated natural classification of the fungi, with illustrated accounts of species linked to molecular data. The present paper introduces the FoF database to the scientific community and briefly reviews some of the problems associated with classification and identification of the main fungal groups. The structure and use of the database is then explained. We would like to invite all mycologists to contribute to these web pages. © 2015, School of Science.
