The family Parmulariaceae comprises three polyphyletic genera, but with very little data in GenBank and is presently placed in the order Asterinales. In this study, we re-analyze the available sequence data for taxa of the family and re-examine the type species of Hemigrapha, Inocyclus and Parmularia. The phylogenetic tree generated from maximum likelihood and Bayesian analyses of combined LSU-SSU sequence data demonstrate the relationships among Hemigrapha, Inocyclus and Parmularia species, and the relations of Buelliella, Karschia, Labrocarpon, Lembosia, Melaspileella, Melaspileopsis and Stictographa. We introduce Parmulariales ord. nov. to accommodate Parmulariaceae and the order Asterinales accommodates Asterinaceae, Asterotexaceae, Hemigraphaceae fam. nov., Melaspileellaceae fam. nov. and Stictographaceae fam. nov. Notes for each new order and families are provided. We confirm that Asterinaceae sensu lato is distant from Asterinaceae sensu stricto in the phylogenic analysis. The classification presented here is provisional, as more species are needed to re-collected and sequenced. We expect further support for our ordinal and familial lineages, as well as further novel lineages.

The genera Lophiostoma, Misturatosphaeria and several other allied taxa in Lophiostomataceae are revisited. Accounts of these taxa, including their history, morphology, and family placement, based on molecular phylogeny, are provided. Type or representative specimens of Lophiostoma and Misturatosphaeria were examined and fresh specimens were obtained from Germany, Italy, Japan and Thailand. A multi-gene phylogenetic analysis of the lophiostomataceous genera Floricola, Lophiostoma, Misturatosphaeria and related taxa is provided. Sixteen genera including Lophiostoma, Lophiohelichrysum, Dimorphiopsis, Platystomum and Vaginatispora, plus eleven newly introduced genera Biappendiculispora, Alpestrisphaeria, Capulatispora, Coelodictyosporium, Guttulispora, Lophiopoacea, Neotrematosphaeria, Paucispora, Pseudolophiostoma, Pseudoplatystomum and Sigarispora are accepted in Lophiostomataceae based on morphology and phylogeny. Lophiostoma caulium, Lophiostoma arundinis and Lophiostoma caudatum are accommodated in Sigarispora. Lophiostoma winteri and Lophiostoma fuckelii are placed in the genera Lophiopoacea and Vaginatispora respectively. Three Curreya species and Misturatosphaeria claviformis are transferred to a new genus, Neocurreya. All other Misturatosphaeria species except Misturatosphaeria aurantiinotata and M. uniseptata are separated in the new genera Asymmetrispora, Aurantiascoma, Magnibotryascoma, Pseudoaurantiascoma and Pseudomisturatosphaeria based on their morphological and phylogenetic affinities. Another new genus, Ramusculicola is introduced for a new collection from Thailand. These seven new genera are accommodated in a new family Floricolaceae, together with Floricola and Misturatosphaeria. Several massarina-like species clustered as a sister clade to Amorosia littoralis and are accommodated in a new genus Angustimassarina. A new family Amorosiaceae is proposed to accommodate the genera Amorosia and Angustimassarina. The putatively named species Decaisnella formosa and Thyridaria macrostomoides form a separate clade together with a new genus Lignosphaeria which is placed in Dothideomycetes, genera incertae sedis.

... Pseudosydowia K.M. Thambugala & K.D. Hyde, Fungal Diversity 68 (2014) Notes: Crous et al. (2003) and Cheewangkoon et al. (2009) showed that Sydowia eucalypti is linked to the asexual morph Selenophoma eucalypti, and phylogenetically clusters with other Aureobasidium and Hormonema species. However, Thambugala et al. (2014c) showed that Sydowia eucalypti is not congeneric with Sydowia sensu stricto (Dothideaceae) and clustered in Aureobasidiaceae and hence introduced a new genus Pseudosydowia to accommodate the taxon. (1930) Notes: Shoemaker (1962) and Sivanesan (1984) stated that Pyrenophora has Drechslera asexual states. ...

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.
A study of freshwater fungi in Thailand led to the discovery of Mycoenterolobium aquadictyosporium sp. nov. Evidence for the novelty and placement in Mycoenterolobium is based on comparison of morphological data. The new species differs from the type species, M. platysporum, in having shorter and wider conidia, and from M. flabelliforme in having much longer and wider conidia. The hyphomycetous genus Mycoenterolobium is similar to Cancellidium but differs in the arrangement of conidial rows of cells at the attachment point to the conidiophores. The conidia of the former are made up of rows of cells, radiating in a linear pattern from a single cell attached to the conidiophore, while in Cancellidium, adherent rows of septate branches radiate from the conidiophore. Cancellidium conidia also contain branched chains of blastic monilioid cells arising from the conidia, while these are lacking in Mycoenterolobium. At maturity in Mycoenterolobium, the two conidial lobes unite and are closely appressed. Phylogenetic analyses based on a combined LSU, SSU, ITS, TEF1-α, and RPB2 loci sequence data support the placement of Mycoenterolobium aquadictyosporium close to the family Testudinaceae within Pleosporomycetidae, Dothideomycetes. The novel species Mycoenterolobium aquadictyosporium is described and illustrated and is compared with other morphologically similar taxa.

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.

The family Pleosporaceae includes numerous saprobic, opportunistic human, and plant pathogenic taxa. The classification of genera and species Pleosporaceae has been a major challenge due to the lack of a clear understanding of the importance of the morphological characters used to distinguish taxa as well as the lack of reference strains. Recent treatments concluded that Pleospora and some other genera in Pleosporaceae are likely polyphyletic. In order to establish the evolutionary relationships and to resolve the polyphyletic nature of Pleospora and allied genera, we sequenced the 18S nrDNA, 28S nrDNA, ITS, GAPDH, RPB2 and TEF1-alpha gene regions of Pleosporaceae species and phylogenetically analysed this data. Multigene phylogenies strongly support the monophyletic nature of Pleosporaceae among the other families in Pleosporales, and the acceptance of the genera Alternaria, Bipolaris, Clathrospora, Comoclathris, Curvularia, Dactuliophora, Decorospora, Diademosa, Exserohilum, Extrawettsteinina, Gibbago, Neocamarosporium, Paradendryphiella, Platysporoides, Pleospora, Porocercospora, Pseudoyuconia and Pyrenophora. Austropleospora, Dendryphion, Edenia and Macrospora are excluded from the family based on morphology coupled with molecular data. Two novel species, Alternaria murispora in this paper and Comoclathris sedi are introduced. The sexual morph of Alternaria alternata is re-described and illustrated using modern concepts from fresh collections. The paraphyletic nature of Pleospora is resolved based on the available morpho-molecular data, but further sampling with fresh collections, reference or ex-type strains and molecular data are needed to obtain a natural classification of genera and the family.
