TL;DR: This paper reviews the 107 families of the class Sordariomycetes and provides a modified backbone tree based on phylogenetic analysis of four combined loci, with a maximum five representative taxa from each family, where available.
Abstract: Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi characterized mainly by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, coprophilous and fungicolous, lichenized or lichenicolous taxa. They occur in terrestrial, freshwater and marine habitats worldwide. This paper reviews the 107 families of the class Sordariomycetes and provides a modified backbone tree based on phylogenetic analysis of four combined loci, with a maximum five representative taxa from each family, where available. This paper brings together for the first time, since Barrs’ 1990 Prodromus, descriptions, notes on the history, and plates or illustrations of type or representative taxa of each family, a list of accepted genera, including asexual genera and a key to these taxa of Sordariomycetes. Delineation of taxa is supported where possible by molecular data. The outline is based on literature to the end of 2015 and the Sordariomycetes now comprises six subclasses, 32 orders, 105 families and 1331 genera. The family Obryzaceae and Pleurotremataceae are excluded from the class.

TL;DR: This paper illustrates, describes, and provides taxonomic notes for 235 dematiaceous coelomycetous genera, including five new genera viz.
Abstract: Coelomycetous fungi are an artificial taxonomic group which produce conidia inside a cavity i.e. conidiomata. Coelomycetes comprise about, 1000 genera and 7000 species, which can be endophytic, pathogenic or saprobic. Traditional classification of coelomycetes was previously based on morphology, such as the shape of conidiomata and mode of conidiogenesis, while it was treated as a distinct group i.e. Deuteromycotina. Sequence based taxonomic studies has been used to accommodate asexual fungi in a natural classification system, resolve generic boundaries of polyphyletic genera and species complexes, as well as establish asexual-sexual links. Nevertheless, most of genera lack sequence data, thus, morphology based identification is still important when introducing new genera or species. In this paper we illustrate, describe, and provide taxonomic notes for 235 dematiaceous coelomycetous genera, including five new genera viz. Apiculospora, Didymellocamarosporium, Melanocamarosporium, Melnikia and Paulkirkia. Phylogenetic analyses of combined sequence data are provided to show placements of dematiaceous coelomycetes in Dothideomycetes, Leotiomycetes and Sordariomycetes. One-hundred and fifty-two (65 %) of genera have sequence data, thus, their taxonomic placement in a natural classification system, is listed as an outline. However, 83 genera still lack sequence data, hence, they are treated as Ascomycota, genera incertae sedis. In addition, separate analyses are provided where better taxonomic resolution is needed.

TL;DR: In this article, the fungus Trichoderma viride was used for the synthesis of biogenic silver nanoparticles, which significantly inhibited the growth of all tested pathogenic bacteria.
Abstract: Green synthesis of nanoparticles has an increasing benefit because of the rising need for developing environmentally friendly, cost-effective and safe strategies for nanomaterials synthesis. In this study, we investigated the fungus Trichoderma viride, which is used for the synthesis of biogenic silver nanoparticles. The bioreduction of silver nanoparticles (Ag NPs) was observed spectrophotometrically, and the studied Ag NPs were characterized by ultraviolet–visible spectroscopy (UV–Vis), transmission electron microscopy and scanning electron microscopy. The Ag NPs synthesized by T. viride were observed as stabilized and polydispersed globular particles, in sizes ranging from 1 to 50 nm. The antibacterial potential of Ag NPs was evaluated against human pathogenic bacteria. The biogenic Ag NPs significantly inhibited the growth of all tested pathogenic bacteria.

TL;DR: The polyphyletic nature of Dendryphion, Sporidesmium and Torula-like species are partially resolved, but further sampling with fresh collections and molecular data of species are needed to obtain a natural classification.
Abstract: During a north–south latitudinal survey of aquatic fungi on submerged wood and herbaceous material in streams in the Asian region, we collected several hyphomycetous taxa. This paper is part of a series where we provide illustrated accounts of these taxa and place them in a natural classification in the fungi. DNA sequence based phylogenies in recent literature have shown that Dendryphion, Sporidesmium and Torula-like species are polyphyletic in the phylum Ascomycota and their taxonomyhas been problematic due to a lack of understanding of the importance of morphological characters used to delimit taxa, as well as the lack of ex-type or reference strains. Based on multi-locus phylogenies together with morphology, we propose the novel family Distoseptisporaceae (Sordariomycetes) and three novel genera Neotorula (Pleosporales, Dothideomycetes), Distoseptispora (Sordariomycetes) and Pseudosporidesmium (Sordariomycetes). In addition, Dendryphion aquaticum, D. submersum, Distoseptispora fluminicola, D. aquatica, Kirschsteiniothelia submersa, Neotorula aquatica, Sporidesmium aquaticum, S. submersum and S. fluminicola are introduced as new species. Pseudosporidesmium knawiae comb. nov. is proposed to accommodate Sporidesmium knawiae in Sordariomycetes. The polyphyletic nature of Dendryphion, Sporidesmium and Torula-like species are partially resolved, but further sampling with fresh collections and molecular data of species are needed to obtain a natural classification.

TL;DR: Phylogenetic analyses indicate that Muyocopron species form a distinct lineage with the Dyfrolomycetales and Acrospermales lineages, and the new order MuyOCopronales is introduced based on its distinct phylogeny and unique morphological characteristics.
Abstract: Muyocopron species are associated with a wide variety of plant substrates worldwide and presently 57 species epithets are listed in Index Fungorum. Species in this genus form distinctive black, dull, rounded regions on the surface of plants and the genus is probably polyphyletic. The present study clarifies the phylogenetic placement of Muyocopron and related species, using fresh tropical collections from northern Thailand. Three Muyocopron species are characterized based on analyses of combined LSU and SSU sequence datasets. Phylogenetic analyses indicate that Muyocopron species form a distinct lineage with the Dyfrolomycetales and Acrospermales lineages. The new order Muyocopronales with three new Muyocopron species is introduced based on its distinct phylogeny and unique morphological characteristics. The taxonomy and phylogenetic relationships of tropical Muyocopron species are reappraised with suggestions for future work.

TL;DR: The phylogenetic relationships and taxonomy of the genus Nodulosphaeria are discussed, but further sampling with fresh collections, reference or ex-type strains and molecular data are needed to obtain a better and natural classification for the genus.
Abstract: Nodulosphaeria is a ubiquitous genus that comprises saprobic, endophytic and pathogenic species associated with a wide variety of substrates and has 64 species epithets listed in Index Fungorum. The classification of species in the genus has been a major challenge due to a lack of understanding of the importance of characters used to distinguish taxa, as well as the lack of reference strains. The present study clarifies the phylogenetic placement of the genus and related species, using fresh collections from Italy. Four Nodulosphaeria species are characterized based on multi-loci analyses of ITS, LSU, SSU, TEF and RPB2 sequence datasets. Phylogenetic analyses indicate that Nodulosphaeria species group within the family Phaeosphaeriaceae as a distinct genus. The sexual morphs of Nodulosphaeria hirta and N. spectabilis are described and illustrated using modern concepts. Two new Nodulosphaeria species are introduced. The phylogenetic relationships and taxonomy of the genus Nodulosphaeria are discussed, but further sampling with fresh collections, reference or ex-type strains and molecular data are needed to obtain a better and natural classification for the genus.

TL;DR: It is suggested that BRN capped Au-NPs can be used as effective drug delivery carriers of the antibiotic LvN and exhibited enhanced antibacterial activity compared to pure LvN alone.
Abstract: To develop bromelain capped gold nanoparticles (BRN capped Au-NPs) as the effective drug delivery carriers of the antibiotic levofloxacin (LvN) and evaluate antibacterial potential of its bioconjugated form compared to pure LvN. BRN capped Au-NPs were synthesized by in vitro method and bioconjugated to LvN using 1-ethyl-3-(3-dimethylamino-propyl)-carbodiimide as activator to form Au-BRN-LvN-NPs. These were characterized for mean particle size by dynamic light scattering analysis, zeta potential by Zetasizer nanosystem analysis and transmission electron microscopy (TEM) on carbon coated TEM copper grids by TEM respectively. Drug loading efficiency of LvN was calculated using UV-visible spectroscopy by standard curve of pure LvN. Antibacterial efficacy of Au-BRN-LvN-NPs and pure LvN was determined by evaluating minimum inhibitory concentration (MIC) against Staphylococcus aureus and Eschereschia coli. Two peaks were observed in Au-BRN-LvN-NPs spectrum one at 307 nm and other at 526 nm while one peak in BRN capped Au-NPs at 522 nm during UV spectroscopy suggesting red shift. The drug loading efficiency of LvN was found to be 84.8 ± 2.41 %. The diameter of Au-BRN-LvN-NPs and BRN capped Au-NPs were found to be (58.65 ± 2 nm, 38.11 ± 2 nm), zeta potential (-9.01 mV, -13.8 mV) and surface morphology (~13.2 nm, 11.4 nm) respectively. The MICs against S. aureus and E. coli were found to be (0.128 µg/mL, 1.10 µg/mL) for Au-BRN-LvN-NPs and (0.547 µg/mL, 1.96 µg/mL) for pure LvN. The results suggested that BRN capped Au-NPs can be used as effective drug delivery carriers of the antibiotic LvN. The Au-BRN-LvN-NPs exhibited enhanced antibacterial activity compared to pure LvN alone. (Graphical abstract see Figure 1(Fig. 1)).

TL;DR: The present study describes the first life-history traits of threatened fish Esomus danricus from the Ganges River, northwestern Bangladesh and calculates the form factor, size at first sexual maturity and natural mortality of E. danicus from world-wide different water bodies using available literature.
Abstract: The present study describe the first life-history traits of threatened fish Esomus danricus from the Ganges River, northwestern Bangladesh. This study also calculates the form factor, size at first sexual maturity and natural mortality of E. danricus from world-wide different water bodies using available literature. Sampling was done, using traditional fishing gears including cast net, square lift net and conical trap during January to December 2014. A total of 309 individuals ranging from 2.946.10 cm total length and 0.25-1.38 g body weight were analyzed in this study. The length frequency distributions showed that the 4.00-4.99 cm total length size group was numerically dominant and constituted 50.00% of the total population. The allometric coefficient (b) of the length-weight relationship indicates negative allometric growth (b < 3.0) for E. danricus in the Ganges River. The results also indicate that the length-length relationships were highly correlated (r2 ≥ 0.974). The allometric condition factor varied from 0.015 to 0.018 and Fulton′s condition factor varied from 0.607-0.985. Also the relative condition factor ranges from 0.923 to 1.127 and minimum and maximum values of relative weight were 92.185-112.727 in the Ganges River. The Fulton′s condition factor is the best index for assessing the wellbeing of E. danricus in the Ganges River. According to Wilcoxon signed test the relative weight did not show any significant difference from 100 (p = 0.295), indicating the balance habitat for E. danricus. The form factor was calculated as 0.0033 and the size at first sexual maturity for combined sexes of E. danricus was estimated as 3.98 (~ 4.00) cm total length in the Ganges River, northwestern Bangladesh. In addition, the mean natural mortality was estimated as 2.31 year-1. These results will be useful for sustainable conservation of this threatened fish in the Ganges River and surrounding ecosystem.
TL;DR: The presence of numerous heteromorphisms and the allelic distribution at certain pairs of loci indicate that hybridization and recombination have likely occurred throughout the history of certain samples, possibly due to intercontinental trade.
Abstract: Agaricus endoxanthus is one of the few species of Agaricus , which are broadly distributed across several continents. This typically tropical species has also been introduced and reported from European tropical greenhouses. To better circumscribe this taxon and understand its distribution, we investigated its intraspecific variability. Sixteen collections resembling A. endoxanthus from various regions were selected for morphological examination and sequencing. Through a combined morphological and molecular approach, nine specimens were identified as A. endoxanthus . No major morphological differences were detected among the studied specimens, however their ITS sequence data were highly variable. The presence of numerous heteromorphisms and the allelic distribution at certain pairs of loci indicate that hybridization and recombination have likely occurred throughout the history of certain samples. Based on the genetic distance and phylogenetic analyses, the observed high genetic diversity appeared unlinked to the geographic origin of the samples, possibly due to intercontinental trade. The seven remaining collections resembling A. endoxanthus were identified as A. moelleri , A. punjabensis , a phylogenetically close relative of A. endoxanthus introduced from Pakistan, A. volvatulus and a closely related species. The detailed description of A. volvatulus is given with data obtained from the type specimen and three African collections.
TL;DR: Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data shows that Poaceascoma aquaticum forms a robust clade with P. helicoides in the family Lentitheciaceae (Pleosporales) and is introduced based on its unique morphology and phylogeny.
Abstract: Poaceascoma aquaticum sp. nov. (Lentitheciaceae) was found on decaying bamboo submerged in a freshwater stream in northern Thailand. The new species is introduced based on its unique morphology and phylogeny. Poaceascoma aquaticum is characterized by black, semi-immersed or erumpent, papillate ascomata, bitunicate, cylindrical to cylindric-clavate, short pedicellate asci and filiform, pale brown to brown ascospores. Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data shows that Poaceascoma aquaticum forms a robust clade with P. helicoides in the family Lentitheciaceae (Pleosporales). Poaceascoma aquaticum is described, illustrated and compared with related taxa.
TL;DR: The new species, Lentithecium cangshanense sp.

The species is characterized by its black, semi-immersed to superficial, globose ascomata, cylindrical or obclavate, short pedicellate, bitunicate asci and bi-seriate, fusiform, 1-septate, yellowish to brown ascospores. Phylogenetic analyses of combined LSU, SSU and RPB2 sequence data show that L. cangshanense belongs in the family Lentitheciaceae, order Pleosporales and is a distinct species in the genus. The new species is introduced with an illustrated account and compared with morphologically and phylogenetically similar species.
TL;DR: Maximum likelihood and Bayesian analyses of LSU and SSU sequence data show that C. musarum forms a distinct clade with other genera in Micropeltidaceae within Capnodiales and C. mangiferae clusters in a poorly supported clade in Dothideomycetes.
Abstract: Chaetothyrina musarum and C. mangiferae sp. nov. (Micropeltidaceae, Dothideomycetes) are reported from fruits of Musa sp. ( Musa acuminata × Musa balbisiana ) and Mangifera indica , respectively. Introduction of a new species, Chaetothyrina mangiferae , and provision of a reference specimen for C. musarum with sequence data, supported by morphology will help to stabilize the taxonomy of the genus and family. Maximum likelihood and Bayesian analyses of LSU and SSU sequence data show that C. musarum forms a distinct clade with other genera in Micropeltidaceae within Capnodiales and C. mangiferae clusters in a poorly supported clade in Dothideomycetes, Illustrated accounts of Chaetothyrina musarum (reference specimen) and C. mangiferae are provided and compared with similar taxa. This is the first report of C. musarum causing sooty blotch and flyspeck disease on Musa sp.

TL;DR: The present study provides a new record of the maximum length (16.10 cm TL) for the D. pusilla female and can assist in the management of these two endangered species in the Ganges River ecosystem.
Abstract: Summary
Length-weight relationships (LWRs) were determined for Dermogenys pusilla (n = 75) and Labeo bata (n = 304) from the Ganges River, northwestern Bangladesh, collected between July 2013 and June 2014, using traditional fishing gear (e.g. cast net, square lift net and gill net). Total length (TL) was measured to 0.1 cm and whole body weight (BW) was taken to the nearest 0.1 g for each individual. The TL varied from 6.60 to 16.10 cm for D. pusilla and 7.90–25.20 cm for L. bata. The BW ranged from 1.20 to 10.90 g for D. pusilla and 4.70–167.30 g for L. bata. All LWRs were highly significant (P < 0.001), with all r2 values ≥0.976. Moreover, the present study provides a new record of the maximum length (16.10 cm TL) for the D. pusilla female. The present study can assist in the management of these two endangered species in the Ganges River ecosystem.

Analyses of partial LSU sequence data place the taxon in a monophyletic clade within the order Pleosporales . Morphological characters of the taxon are also distinct from other members of Pleosporales . Ligninsphaeria jonesii gen. et sp. nov. is therefore introduced to accommodate the new taxon, which is characterized by its clypeate, scattered, deeply immersed ascomata, with a slit-like opening, long ostioles, cellular pseudoparaphyses, clavate asci containing broad-fusiform and 1-septate ascospores surrounded by a gelatinous cap at both ends. The phylogenetic analyses show that the new taxon is phylogenetically close but distinct from the families Amniculicolaceae and Testudinaceae , and forms a distinct clade from other taxa in Pleosporales . The new taxon is described and compared with similar taxa. A new genus Ligninsphaeria (Pleosporales, incertae sedis ) is introduced to accommodate this distinct lineage.
TL;DR: The results of this study can be very effective for stock assessment of Mystus species in the Ganges and Rupsha rivers as well as in the surrounding ecosystems.
Abstract: Summary
This study focused on the length–weight and length–length relationships of five Mystus species from Bangladesh. A sum of 398 individuals (Mystus bleekeri = 47, Mystus cavasius = 171, Mystus gulio = 59, Mystus tengra = 65, and Mystus vittatus = 56) was collected from the Ganges and Rupsha rivers, Bangladesh. Fishes were caught by gill net (mesh sizes: 2.0–4.0 cm) and cast net (mesh sizes: 1.5–3.0 cm) from July 2014 to June 2015. Total length (TL), fork length (FL) and standard length (SL) were measured to 0.1 cm, while whole body weight (W) was taken to the nearest 0.1 g for each individual. The TL ranged from 6.0–13.5 cm for M. bleekeri, 5.0–15.0 cm for M. cavasius, 7.4–17.2 cm for M. gulio, 4.6–11.6 cm for M. tengra and 5.5–12.3 cm for M. vittatus. The W varied from 3.0–18.2 g for M. bleekeri, 1.3–30.4 g for M. cavasius, 6.1–62.2 g for M. gulio, 1.7–15.1 g for M. tengra and 2.7–19.2 g for M. vittatus. All LWRs were highly significant (p < .001), with all r2 values ≥.950. The LLRs were also highly significant (p < .001), with all r2 ≥.980. This study provides information on LWRs and LLRs for M. gulio and M. tengra for the first time. The results of this study can be very effective for stock assessment of Mystus species in the Ganges and Rupsha rivers as well as in the surrounding ecosystems.
