Arthrinium has a widespread distribution occurring in various substrates (e.g., air, soil debris, plants, lichens, marine algae and even human tissues). It is characterized by the basauxic conidiogenesis in the asexual morph, with apiospores in the sexual morph. In this study, seventeen isolates of Arthrinium were collected in China. Based on their morphology and phylogenetic characterization, four new species (A. biseriale, A. cyclobalanopsidis, A. gelatinosum, and A. septatum) are described and seven known species (A. arundinis, A. garethjonesii, A. guizhouense, A. hydei, A. neosubglobosa, A. phyllostachium and A. psedoparenchymaticum) are identified, of which the sexual morph of three species (A. guizhouense, A. phyllostachium and A. psedoparenchymaticum) and asexual morph of A. garethjonesii are reported for the first time. The detailed descriptions, illustrations and comparisons with related taxa of these new collections are provided. Phylogenetic analyses of combined ITS, LSU, TUB2, and TEF sequence data support their placements in the genus Arthrinium and justify the new species establishments and identifications of known species.

Decaying Wood

Asexual morph members of Tetraplosphaeriaceae (Pleosporales, Dothideomycetes) are generally hyphomycetes and usually found as saprobes occurring on various hosts in lentic habitats. Two isolates of a novel species, Tetraploa aquatica sp. nov., was collected from submerged decaying wood in Dulong river and a stream of Gaoligongshan mountain in Yunnan Province, China. The new species is characterized by short-cylindrical conidia, composed of 4-euseptate, short-cylindrical vertical columns which are verrucose at the base and with 4-setose vertical septate appendages. Tetraploa aquatica can be easily distinguished from other Tetraploa species by their columns which are 2–3-septate, aguttulate, vertical, setose appendaged which tend to remain parallel to one another apically. Phylogenetic analyses of combined LSU, ITS and SSU sequence data support its natural placement in Tetraploa. Detailed description and illustrations of this species and comparisons with other morphologically similar taxa in Tetraploa are provided.

Β Tubulin

During a survey of fungi on Araucaria araucana in Chile, a species of Ophiostoma morphologically different to O. araucariae was collected in the Andean region. Morphological characteristics and phylogenetic analyses of ITS, β-tubulin and EF-1α sequences confirmed that this species represents a novel taxon. This taxon is described here as Ophiostoma pehueninum sp. nov. The sexual morph of O. pehueninum was characterized by long neck and peridial hyphae around the bases, and allantoid ascospores surrounded by a gelatinous sheath. In culture a hyalorhinocladiella-like asexual morph was observed. Mating compatibility tests indicated that the species is heterothallic.

Acrocordiella yunnanensis sp. nov. is introduced here from dead twigs of an unidentified dicotyledonous host from Xishuangbanna Prefecture, Yunnan Province, China. Phylogenetic analyses based on LSU and ITS sequence data revealed that this new species with a distinct sexual morph belongs to Requienellaceae (Sordariomycetes, Ascomycota). Acrocordiella yunnanensis is closely related to Acrocordiella omanensis in Requienellaceae. This novel taxon is illustrated, described, and a morphology-based key is provided to facilitate the identification of species in Acrocordiella.

A New Species

Gibellula is an exclusively spider-pathogen genus, with most species immediately recognized by their distinctive conidial state, but also including the teleomorphic states of these fungi that were previously included in the rejected genus Torrubiella. Two sexual specimens and an asexual morph specimen were collected from Anhui Province, China, and were recognized as the same species based on molecular evidence. Its asexual morph differs from Gibellula pulchra, to which it is morphologically similar, in having shorter verrucose conidiophores with slightly smaller metulae, phialides and conidia. Its sexual morph is characterized by producing superficial and elongate ellipsoid small perithecia with short asci on a cream-yellow mycelial mat covering the host. Multi-locus (SSU, LSU, TEF, and RPB1) phylogenetic analyses showed that the specimens belong to a strongly supported subclade, and formed a sister subclade with G. pulchra and Gibellula sp. A combination of morphological characteristics and its phylogenetic placement confirmed that these unique specimens are a new species, which is described as Gibellula flava.

AbstractIn a recent revision of the genus Agaricus, A. section Xanthodermatei was split into two sections A. sect. Hondenses and A. sect. Xanthodermatei. Our objectives were to investigate the species diversity of both sections in Pakistan and to give an overview of the major clades. Phylogenetic analyses based on the combined nucLSU, ITS and TEF1 dataset from 35 specimens of both sections revealed three major clades. Analyses based on ITS dataset and 106 specimens, including 33 from Pakistan, reveal eight new species and one new record species. These nine species are described in detail. It is noteworthy that intraspecific variability as well as interspecific variability between closely related species were very low in ITS sequences in many cases. In the case of the two new species A.xanthochromaticus and A.griseovariegatus, TEF1 sequence data were much more efficient than ITS to distinguish these species from each other. The other new species are A.atroumbonatus, A.fumidicolor, A.macropeplus, A.parviniveus, A.swaticus and A.bambusetorum. The latter is the only new species of A. sect. Hondenses in which it is morphologically atypical and also the unique (sub)tropical species. Agaricusgregariomyces is recorded for the first time in Pakistan. In addition, brief descriptions are provided not only for A.bisporiticus, A.endoxanthus and A.punjabensis, which are reported again in Pakistan, but also for A.californicus, which is reported for the first time in Spain and outside North America. In total 12 species of both sections were reported in Pakistan and half of them were from subtropical climatic areas, underlining the contribution of the climatic diversity to the high species richness in this country.

Interesting Species

AbstractCollections of microfungi on bamboo and grasses in Thailand revealed an interesting species morphologically resembling Lophiostoma, but which can be distinguished from the latter based on multi-locus phylogeny. In this paper, a new genus, Sublophiostoma is introduced to accommodate the taxon, S. thailandica sp. nov. Phylogenetic analyses using combined ITS, LSU, RPB2, SSU, and TEF sequences demonstrate that six strains of the new species form a distinct clade within Pleosporales, but cannot be assigned to any existing family. Therefore, a new family Sublophiostomataceae (Pleosporales) is introduced to accommodate the new genus. The sexual morph of Sublophiostomataceae is characterized by subglobose to hemisphaerical, ostiolate ascomata, with crest-like openings, a peridium with cells of textura angularis to textura epidermoidea, cylindric-clavate asci with a bulbous or foot-like narrow pedicel and a well-developed ocular chamber, and hyaline, fusiform, 1-septate ascospores surrounded by a large mucilaginous sheath. The asexual morph (coelomycetous) of the species are observed on culture media.

The morphology and phylogeny of two new sessilid species, Zoothamnium weishanicum n. sp. and Epicarchesium sinense n. sp., two insufficiently known species, Zoothamnium arbusculaEhrenberg, 1831 and Zoothamnium hentscheliKahl, 1935, and a well-known species, Carchesium polypinum (Linnaeus, 1767) Ehrenberg, 1838, collected from freshwater habitats of China, were investigated. Zoothamnium weishanicum n. sp. is characterized by its inverted bell-shaped zooids, double-layered peristomial lip, alternately branched stalk, and two different-length rows in infundibular polykinety 3 (P3). Epicarchesium sinense n. sp. is recognized by its asymmetric-pyriform zooids, single-layered peristomial lip, conspicuous cortical blisters on the pellicle, dichotomously branched stalk, and P3 containing one short inner row and two long outer rows. Based on previous and newly obtained data of the three known species, improved diagnoses and redescriptions are provided including, for the first time, data on the infraciliature of Z. arbuscula and Z. hentscheli. In addition, we analyzed the phylogeny of each species based on SSU rDNA sequence data.

A New Species

Collections of microfungi on Pandanus species (Pandanaceae) in Krabi, Thailand resulted in the discovery of a new species in the genus Parasarcopodium, producing both its sexual and asexual morphs. In this paper, we introduce P. pandanicola sp. nov., with an illustrated account. Evidence for the new species is provided by distinct morphology and phylogenetic analyses. This is also the first report of the sexual morph of Parasarcopodium. The phylogenetic trees used Maximum Likelihood and Bayesian analyses of combined LSU, SSU, TEF1 and RPB2 sequence data to show the placement of the new species in Stachybotryaceae.

Collections of eleven Prunus specimens infected with Polystigma species from Belarus and Russia yielded two existing taxa: Polystigma fulvum (sexual morph) and Polystigma rubrum (asexual morph). DNA based phylogenies of large subunit nuclear rDNA (LSU) and nuclear ribosomal internal transcribed spacer (ITS) are provided for the first time for Polystigma fulvum and its placement is confirmed within Polystigmataceae. The concatenated LSU and ITS DNA sequence data for P. rubrum, analyzed to infer its potential relationship to other Polystigma species, also show that strains of P. rubrum are segregated into two subclades with sufficient genetic differences. No significant differences in morphology or morphometry among the strains of P. rubrum between the two subclades, especially vis-à-vis the conidiogenous cell and conidium sizes are observed (P>0.05). Subspecies concept of P. rubrum complex is discussed.

Vaucheria is a genus of yellow-green algae, the taxonomy of which is based on the morphology of antheridia and oogonia. Distribution of Vaucheria in New Zealand is poorly understood. Only two studies have investigated phylogenetic relationships in the genus world-wide and these omitted some of the diversity found in New Zealand. We identified seven species of Vaucheria based on morphology of their reproductive structures. Two were described as new species (V. aestuarii and V. edaphica), two were reported for the first time from New Zealand (V. erythrospora and V. litorea), one has been reported previously (V. bursata), and the identification of the remaining two was inconclusive (Vaucheria cf. borealis and Vaucheria cf. conifera). The genetic variation and phylogenetic position of these species were studied using phylogenetic analyses of rbcL sequences. These showed the existence of morphologically indistinguishable cryptic species complexes in sect. Corniculatae. Our results were mostly consistent with the current morphology-based sectional classification of the genus.
