Rubusdianchuanensis sp. nov. (Rosaceae) from Sichuan and Yunnan, southwest China.

ABSTRACT: Rubusdianchuanensis, a new name for the species previously named as R.vicarius by W. O. Focke in 1911, is proposed. A detailed description, illustrations, and remarks on its phenology, ecology, and geographic distribution are provided. This raspberry (subg. Idaeobatus) is endemic to China and was only found in Sichuan and Yunnan, southwest China. Morphologically, it is most similar to R.ovatisepalus but clearly differs from the latter by having leaf densely white or grey tomentose abaxially, usually leaf-like bracts at the base of inflorescence, 1-6 cm long pedicels, and triangular-ovate sepals with acute to caudate apex.

Ganodermaovisporum sp. nov. (Polyporales, Polyporaceae) from Southwest China.

Project description:BackgroundGanoderma is a white-rot fungus with a cosmopolitan distribution and includes several economically important species. This genus has been extensively researched due to its beneficial medicinal properties and chemical constituents with potential nutritional and therapeutic values. Traditionally, species of Ganoderma were identified solely based on morphology; however, recent molecular studies revealed that many morphology-based species are conspecific. Furthermore, some type species are in poor condition, which hinders us from re-examining their taxonomic characteristics and obtaining their molecular data. Therefore, new species and fresh collections with multigene sequences are needed to fill the loopholes and to understand the biological classification system of Ganoderma.New informationIn a survey of Ganoderma in Guizhou Province, southwest China, we found a new species growing on soil and, herein, it was identified by both morphology and phylogenetic evidence. Hence, we propose a new species, Ganodermaovisporum sp. nov. This species is characterised by an annual, stipitate, laccate basidiome, with a red-brown to brownish-black pileus surface and pale white pores, duplex context, clavate pileipellis terminal cells, trimitic hyphal system, ellipsoid basidiospores with dark brown eusporium bearing coarse echinulae and an obtuse turgid appendix. Phylogenetic analyses confirmed that the novel species sisters to G.sandunense with high bootstrap support. Furthermore, the RPB2 sequence of G.sandunense is supplied for the first time. Notably, we re-examined the type specimen of G.sandunense and provide a more precise description of the duplex context, pileipellis terminal cells and basidia. All species collected are described and illustrated with coloured photographs. Moreover, we present an updated phylogeny for Ganoderma, based on nLSU, ITS, RPB2 and TEF1-α DNA sequence data and species relationships and classification are discussed.

Hyphoderma pinicola sp. nov. of H. setigerum complex (Basidiomycota) from Yunnan, China.

Project description:BackgroudHyphoderma setigerum (Fr.) Donk is a white-rot wood-decaying corticoid fungal species. It occurs worldwide from tropical to temperate regions. However, taxonomic studies in recent decades showed that H. setigerum is a species complex with four separate species, before this study.ResultsHyphoderma pinicola sp. nov. was collected on dead wood of Pinus yunnanensis Franch. in the temperate montane belt at 2200-2400 m altitudes, in Yunnan Province of China. Within the H. setigerum complex this new taxon is distinguished by having 2-sterigmate basidia, long basidiospores, and nearly naked septocystidia. A description and illustrations of this new species are provided, along with a key to five species of the H. setigerum complex. Phylogenetic reconstruction based on 5.8S-ITS2 sequences indicated that H. pinicola belongs to the H. setigerum complex and has a separate position within the clade including H. subsetigerum and H. setigerum s.s. Bayesian inference of phylogeny based on two datasets, ITS and 28S nuclear ribosomal DNA sequences, confirmed the independent status of H. pinicola.ConclusionMorphological and phylogenetic studies showed that H. pinicola represents a fifth species of H. setigerum complex.

Neostagonosporellasichuanensis gen. et sp. nov. (Phaeosphaeriaceae, Pleosporales) on Phyllostachysheteroclada (Poaceae) from Sichuan Province, China.

Project description:Neostagonosporellasichuanensis sp. nov. was found on Phyllostachysheteroclada collected from Sichuan Province in China and is introduced in a new genus Neostagonosporella gen. nov. in this paper. Evidence for the placement of the new taxon in the family Phaeosphaeriaceae is supported by morphology and phylogenetic analysis of a combined LSU, SSU, ITS and TEF 1-α DNA sequence dataset. Maximum-likelihood, maximum-parsimony and Bayesian inference phylogenetic analyses support Neostagonosporella as a distinct genus within this family. The new genus is compared with related genera of Phaeosphaeriaceae and full descriptions and illustrations are provided. Neostagonosporella is characterised by its unique suite of characters, such as multiloculate ascostromata and cylindrical to fusiform, transversely multiseptate, straight or curved ascospores, which are widest at the central cells. Conidiostromata are multiloculate, fusiform to long fusiform or rhomboid, with two types conidia; macroconidia vermiform or subcylindrical to cylindrical, transversely multiseptate, sometimes curved, almost equidistant between septa and microconidia oval, ellipsoidal or long ellipsoidal, aseptate, rounded at both ends. An updated phylogeny of the Phaeosphaeriaceae based on multigene analysis is provided.

Quasipucciniastrum agrimoniae, gen. et sp. nov. on Agrimonia (Rosaceae) from China.

Project description:A new rust genus, Quasipucciniastrum, typified by Q. agrimoniae sp. nov., is proposed based on distinct morphological characters and phylogenetic placement. This genus is characterised by its uredinial ostiolar peridial cells with rough surface and sessile, multicellular teliospores with apparently thickened apical wall. Molecular phylogenetic analyses using internal transcribed spacer regions and intervening 5.8S nrRNA gene (ITS) and the large subunit (LSU) rDNA revealed that this genus is sister to the genus Cronartium (Cronartiaceae), but morphologically it is distinct from Cronartium in the sessile teliospores that are divided by vertical septa. Morphologically, Quasipucciniastrum should be compared to Pucciniastrum (Pucciniastraceae) in its multicellular teliospores, but they were phylogenetically distant.

Neomonodictysaquatica sp. nov. (Pleurotheciaceae) from a plateau lake in Yunnan Province, China.

Project description:BackgroundIn this study, a new species Neomonodictysaquatica was collected from submerged decaying wood in Erhai Lake, Yunnan Province, China.New informationNeomonodictysaquatica is characterised by acrogenous, solitary, oval, dictyospores (most are transverse septum, occasionally vertical septum, in immaturity the septum is clear, but when mature, the conidia becomes darker so the septum is not clear), smooth-walled conidia. The immature conidia are usually hyaline to olivaceous and mature conidia are usually darkened to black, sometimes with one pale basal cell. Phylogenetic analyses of combined ITS and LSU sequence data showed that the new collection is distinct from other Neomonodictys species. Description and illustration are provided as well.

Brunneosporopsis yunnanensis gen. et sp. nov. and Allocryptovalsa xishuangbanica sp. nov., New Terrestrial Sordariomycetes from Southwest China.

Project description:Three fungal taxa were collected on dead branches of wood during fieldwork in Sichuan and Yunnan Provinces, China. The new generic name Brunneosporopsis gen. nov. and species B. yunnanensis sp. nov. are introduced for a novel taxon characterized by globose to subglobose and dark olivacous-brown conidia. Phylogenetic analyses based on combined LSU, SSU and tef1-α loci strongly support the monophyly of this taxon and place it in the subclass Diaporthomycetidae. It could not be assigned to any currently recognized families in the subclass and was, therefore, placed in the Diaporthomycetidae genera incertae sedis. A second taxon represents a new species in Allocryptovalsa based on an analysis of the sequence datasets of ITS and btub loci of the novel, brown-spored sexual morphic species. This taxon is described here as A. xishuangbanica sp. nov. An interesting hypocrealean fungus producing synnemata, Stilbocrea gracilipes, was collected from dead wood of an unknown host from Sichuan Province and is reported here, with asexual morph from both the host and culture as well as LSU, ITS, tef1-α, rpb2 and rpb1 sequence data.
