A New Species

A new species of the xenodermatid snake genus Achalinus Peters, 1869 is described from Yunnan Province, Southwest China, based on a single male specimen. The new species is assigned to the genus Achalinus on the basis of absence of preocular and postocular, subcaudals arranged in single row, and results of phylogenetic analyses of mitochondrial DNA CO1 sequence data. Achalinus pingbianensis sp. nov. differs from its congeners by the combination of following morphological characters: absence of a loreal, internasals subequal to that between prefrontals and dorsal scales strongly keeled, 23 rows throughout. Currently, 13 species are in the genus Achalinus, further taxonomical and phylogenetic studies based on more extensive samples and more markers will help understand the cryptic diversity and clarify their interspecific relationships.

A New Species

A new Seifertia species was isolated from hanging rachides of Rhododendron decorum in Yunnan Province, Southwest China. The new taxon was compared with the type species, S. azalea and differs in having wider conidiophores, with hyaline to subhyaline and smaller conidia, while S. azalea has olive-brown to brown, rarely branched conidiophores, and pale brown or olive-brown, very rarely septate conidia. Phylogenetic analyses of combined LSU, SSU and TEF1-α sequence data show that S. shangrilaensis forms a robust clade with S. azalea nested among the species of Melanommataceae in the order Pleosporales. A new species, S. shangrilaensis is introduced in this study, and Seifertia should be placed in Melanommataceae (Pleosporales, Dothideomycetes) based on phylogenetic analysis. Description and illustration of Seifertia shangrilaensis are provided with notes and its introduction is supported by molecular data.

A New Species

Species of Psilocybe collected in Yunnan Province in southwest China were identified using both morphological characteristics and phylogenetic analyses of ITS and nrLSU sequence data. Six phylogenetic species were recognized among the studied collections. In this paper, Psilocybe ruliensis is introduced as a new species, while Psilocybe keralensis is new to China, P. aff. fasciata is new to Yunnan and P. chuxiongensis is recollected in Yunnan Province. The remaining two phylogenetic species are not described or detailed due to the paucity of the material. The four species appear to be endemic to Asia.

The genus Phillipsia (Sarcoscyphaceae) is characterized by large, bright-coloured, sub-stipitate apothecia, sub-operculate asci and asymmetrical ascospores with longitudinal striations. Morphological and phylogenetic studies were carried out on new collections of Phillipsia from China and Thailand. Phillipsia subpurpurea are recorded from China and Phillipsia gelatinosa from Thailand is introduced as a new species to science. Our new collections are confirmed to be divergent from other species of Phillipsia based on morphological examination and molecular phylogenetic analyses of ITS and LSU sequence data. Descriptions and figures are provided for the taxa which are also compared with allied taxa.

A New Species

A new species of the genus Gonyosoma Wagler is described from Yunnan Province, China. The new species closely resembles G. prasinum (Blyth), but it is differentiated from the latter species by the following characters: precloacal plate divided, iris blue and inside of mouth greyish-white in life. Based on phylogenetic analyses of mitochondrial cytochrome b sequence data, the new species is recovered as the sister species to G. prasinum by Bayesian Inference and Maximum Likelihood analyses. The uncorrected pairwise distance between the new species and other species of the genus Gonyosoma ranged from 11.78% to 17.07% calculated using the mitochondrial cytochrome b sequence. This discovery increases the number of Gonyosoma species to seven.

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

A New Species

Didymosphaeriaceae is a ubiquitous fungal family that is reported to include saprobic, endophytic and pathogenic species associated with a wide variety of substrates. The family is characterized by 1-septate ascospores and trabeculate pseudoparaphyses, mainly anastomosing above the asci. In recent treatments Appendispora, Didymosphaeria, Roussoella, Phaeodothis and Verruculina were placed in the family. The aim of the present study is to delineate phylogenetic lineages within Didymosphaeriaceae and allied genera. A new species, Didymosphaeria rubi-ulmifolii, was isolated and identified based on morphological characters and phylogenetic analyses of partial 18S nrDNA and 28S nrDNA nucleotide sequence data. Didymosphaeria rubi-ulmifolii clustered with Montagnulaceae as a separate genus, while two putative strains (HKUCC 5834 and CMW 22186) of D. futilis from GenBank clustered with Cucurbitariaceae and Didymellaceae, respectively. The new species is characterized by immersed to slightly erumpent ascomata immersed under a clypeus, a peridium with compressed cells of textura intricata, long trabeculate pseudoparaphyses, anastomosing mostly above the asci and brown, 1-septate ascospores with granulate ornamentation. Phylogenetic analysis in combination with morphology and a review of literature show that Appendispora, Phaeodothis, Roussoella and Verruculina should be excluded from the family. Phaeodothis belongs in Montagnulaceae, Verruculina in Testudinaceae, while Appendispora and Roussoella belong in Roussoellaceae. The position of Didymosphaeriaceae as a distinct family, based on 1-septate ascospores and trabeculate pseudoparaphyses, mainly anastomosing above the asci is doubtful. Fresh collections of more Didymosphaeria strains are needed for epitypification and to obtain sequence data to establish if this family can be maintained.

A new species of the natricine snake genus Hebius Thompson, 1913 is described from Sichuan Province, Southwest China, based on a single male specimen. The new species is distinguished from its congeners found in China and adjacent regions by possessing the following combination of characters: 1) TL/SVL ratio 0.35; 2) three postoculars; 3) six temporals in formula 1/(1+1) +1+2; 4) eight supralabials, 4th and 5th in contact with the eye, 6th supralabial largest; 5) ten infralabials with the first five bordering the anterior chinshields; 6) 172 ventrals (plus two preventrals); 7) cloacal plate divided; 8) 90 divided subcaudals; 9) dorsal scales in 19-19-17 rows, all weakly keeled except the outer two; 10) reduction of dorsal scale rows from 19 to 17 at the position above ventral scale 99th; 11) reduction of the tail dorsal scales from 8 to 6 rows at the position above 18th subcaudal, and from 6 to 4 rows at the position above 37th subcaudal; 12) postorbital bones do not touch frontals, the parietal ridge weakly developed; the end of the supratemporal bones extending beyond the braincase; maxillary teeth 23–25, the last two enlarged, without diastema between them and the anterior teeth. This species is an evergreen forest dweller.

A New Species

We describe a new Diploderma species from Southern Yunnan Province, China. It is morphologically similar to D. chapaense, D. hamptoni, and D. yunnanense, but can be distinguished from these three species and all other congeners by its unique morphometric and meristic characters, color patterns and localized distribution range. Moreover, phylogenetic analyses of mitochondrial gene NADH dehydrogenase subunit 2 sequence data also supports this point of view; the new species differs genetically from investigated congeners by percentage distance of 8.78 to 21.15%.

During a survey of freshwater fungi in Guizhou Province, China, a collection from a submerged decaying twig in Baihua Lake was identified as a new species of Sporidesmium sensu lato based on morphological characters and phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB2 sequence data. Phylogenetic analyses supported its placement in Sordariomycetes but the fungus grouped distant from Sporidesmium sensu stricto, and its ordinal or familial position within the class remained inconclusive. Sporidesmium guizhouense sp. nov. is introduced with an illustrated account and notes on its taxonomy, phylogeny and systematic position are provided.
