New Geographical Record

Eight freshwater asexual strains collected from China and Thailand were subjected to morpho-molecular analyses. BLAST search results showed that the new strains belonged to Pleurotheciales, Sordariomycetes. Phylogenetic analyses based on a combined LSU, SSU, ITS and RPB2 sequence dataset are used to clarify the placement of the new strains within Pleurotheciales. Pleurothecium guttulatum and Pleurotheciella sympodia are introduced as two new species from freshwater habitats. New geographical record of Pleurotheciella nilotica from Asia (Thailand and China) is reported. New habitat and geographical records of Phaeoisaria annesophieae (from freshwater habitats in Asia) are reported. Descriptions and illustrations of the new species and records, as well as known species Rhexoacrodictys erecta and Phaeoisaria annesophieae, are provided. A key to Pleurotheciella species is provided.

Guepinia alba sp. nov. and G. shanxiense sp. nov. are described and illustrated from Northern China in this paper. Morphologically, G. alba is distinguished from other Guepinia species by whitish basidiomata and 4-spored basidia while G. shanxiense is diagnosed by reddish orange basidiomata and ellipsoid to oblong ellipsoid basidiospores. Molecular phylogenetic analyses based on ITS and nrLSU sequences support the establishment of the two new species.

Two new myxomycetes from subtropical forests of China, Arcyria aeruginosa sp. nov. and Diderma subochraceum sp. nov., are described and illustrated. Arcyria aeruginosa occurred on rotten stem of bamboo and differs from all known species of the genus in having dense spines on inner surface of cups. The diagnostic feature of D. subochraceum is single-layered peridium which dehisces by longitudinal or stellate slit. Preliminary phylogenetic analyses based on partial 18S rDNA sequences support the establishment of the two new species. Additionally, Didymium saturnus H.W. Keller and Fuligo luteonitens L.G. Krieglst. & Nowotny are reported from China for the first time.

During investigations into freshwater fungi from the Great Mekong Subregion, four Distoseptispora taxa were collected from China and Thailand. Based on morphological characteristics, and phylogenetic analyses of combined LSU, ITS, SSU, TEF1-α, and RPB2 sequence data, two new species Distoseptispora bangkokensis and D. lancangjiangensis are introduced, and two known species D. clematidis and D. thysanolaenae were first reported in freshwater habitat. Illustrations and descriptions of these taxa are provided, along with comparisons with extant taxa in the genus.

Whilst, M. sembilingensisis differ from M. multiflora and M. hispida by the floral and fruit morphologies.

Distoseptispora is one of the sporidesmium-like taxa with great variation in asexual morphology and delineation of species. Phylogenetic analyses of four gene regions LSU, ITS, TEF1α, and RPB2 revealed the placement of several sporidesmium-like species in Distoseptispora (Distoseptisporaceae, Distoseptisporales, Sordariomycetes), collected on submerged decaying twigs from streams in China and Thailand. Based on morphological examination and molecular DNA data, six new species, Distoseptispora amniculi, D. atroviridis, D. effusa, D. fusiformis, D. hyalina, and D. verrucosa, are proposed. Among them, D. hyalina is the first sexual morph confirmed in the genus. A new geographical record is reported for D. lignicola in China. Conidial length proved to be of less taxonomic significance for some Distoseptispora species, whereas the type of conidial septa is informative at species level.

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.

Two new Platanthera (Orchidinae, Orchideae, Orchidoideae) species, P. guangdongensis and P. zijinensis, from the Guangdong Province in China are described and illustrated based on morphological and molecular analyses. Platanthera guangdongensis is leafless and resembles P. fujianensis, but it differs in terms of the shorter and/or smaller inflorescence, floral bract, dorsal sepal, lateral sepal, petal, and ligulate lip. Platanthera zijinensis is morphologically similar to P. minor, but it differs by the ovate-oblong to ovate floral bract, colour of flower, ovate dorsal sepal, oblong lateral sepal, ovate-oblong lip, and curved forward spur. The phylogenetic analyses based on nuclear ribosomal ITS and chloroplast (rbcL and matK) sequence data support that P. zijinensis and P. guangdongensis being sisters to each other and genetically sister to P. minor. The chloroplast rbcL of P. guangdongensis is a pseudogene, supporting its characterization as a holomycotrophic orchid.

A New Species

Abstract Ephemeral pools are biologically important habitats for species adapted to survive through a dry phase. Unfortunately, these pools have been neglected in studies. Copepods are essential in aquatic habitats mainly because of their importance in the food web. Currently there are only 34 species reported from freshwater habitats in South Africa. This study was conducted in an ephemeral pool (Limpopo Province, South Africa). Qualitative sampling was done monthly (December 2014 to June 2015) using a plankton net and specimens were studied through a light microscope. Seven species were collected, three from Calanoida and four from Cyclopoida, including a new species, Microcyclops raynerae. Seven species represent quite a high biodiversity of copepods from a single pool when compared with similar studies previously done in South Africa. The report of Tropocyclops confinis constitutes a new geographical record from South Africa while all other collected species are new records from the Limpopo Province.
