Youngia hangii T.Deng, D.G.Zhang, Qun Liu & Z.M.Li, sp. nov., a new species of Asteraceae, is described and illustrated. It was collected in Wufeng County, Hubei Province, Eastern Central China. Youngia hangii is morphologically most similar to Y. rubida, but can be easily distinguished from the latter by capitula with 8–10 florets and the hairy leaf surface. Phylogenetic analyses, based on the internal transcribed spacers (ITS) and one chloroplast marker (rps16), showed that Y. hangii and Y. rubida were sister species with good support. The results of both phylogenetic analysis and the morphological data support the specific rank of Y. hangii.

A New Species

Here we describe Oxytropis shennongjiaensis, a new species of Fabaceae from Central China (Hubei Province). Morphologically, O. shennongjiaensis is closely similar to O. sitaipaiensis, O. melanocalyx and O. kansuensis, but differs in stem characters, with less conspicuous internodes; persistent herbaceous stipules; pale yellow to white corolla; and stipitate legumes, 3–5 mm with a long beak. Phylogenetic analysis, based on the internal transcribed spacers (ITS) and two chloroplast markers (trnL–F and psbA–trnH), also identified O. shennongjiaensis as a new species, which is consistent with our morphological analyses. Considering the morphological data and phylogenetic data presented here, we believe that this evidence satisfies the required diagnostic criteria to identify O. shennongjiaensis as a new species.

A New Species

This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involucrata are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.

A New Species

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

Trichosanthes sunhangii D.G.Zhang, Z.M.Li, Qun Liu & T.Deng, a new species of Cucurbitaceae, is described and illustrated. It was collected in Shennongjia Forestry District, Hubei province, east-central China. T. sunhangii is morphologically similar to T. kirilowii Maxim. and T. rosthornii Harms, but can be easily distinguished from them by its bracts, tendrils and fruits. Phylogenetic analyses based on three DNA barcode markers (ITS, matK and rpl20-rps12) indicated that two accessions of T. sunhangii were grouped together (PP=1.00, BP=100 and LP=100) in Sect. Foliobracteola.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

A New Species

Adenophora xiaoxiensis (Campanulaceae), a new species from central China is described and illustrated. Molecular phylogenetic analysis (based on nuclear ribosomal ITS and the plastid regions trnL-F and matK) and morphology support recognition of A. xiaoxiensis as a distinct species sister to A. wilsonii. Adenophora xiaoxiensis has ovate-elliptic to broadly lanceolate cauline leaves with irregularly biserrate margins, triangular-ovate calyx lobes with 1-3 pairs subulate or linear teeth and a white corolla. About 70 individuals were observed in a restricted area of less than 100 m2. The habitat could be easily disturbed or destroyed, thus, we assessed it as endangered (EN), based on Criteria D of the International Union for Conservation of Nature Red List Categories.

Pseudohydnum brunneiceps is described as a new species from Jiangxi Province, central China. Morphologically, it is characterized by a gelatinous basidiocarps, pilei pale yellowish brown, dark reddish brown to blackish velutinate, spines conical and white, and basidiospores globose to broadly ellipsoidal. Phylogenetic analyses of DNA sequences from partial 28S region and internal transcribed spacer (ITS) also confirm that P. brunneiceps forms an independent lineage within Pseudohydnum. A description, photographs of the fresh basidiomata and line-drawings of the microstructures are provided. In addition, the previous records of P. gelatinosum in China should be re-evaluated by more representative samples by molecular phylogeny.

Abstract Background Hyoscyamus, the largest genus in the tribe Hyoscyameae, harbors more than 20 species. Although the monophyly of Hyoscyamus is supported by both morphological and molecular phylogenetic studies, the delimitation of Hyoscyamus has been hotly debated in different classifications. Here, we report a new species of Hyoscyamus (Solanaceae) from Henan Province, China, and discuss the delimitation of Hyoscyamus. Results This species is morphologically similar to the known species of Hyoscyamus and its close related genus Archihyoscyamus, but can be distinguished by corolla 2-lipped, adaxial lip 3-lobed and much longer than abaxial lips, tube slender at base, and stamens 5, inserted on inner side of disk, free, obviously unequal, and exceeding corolla. Phylogenetic analysis based on four chloroplast markers including rbcL, ndhF, trnC-psbM and trnL-trnF, strongly suggested that the new species was sister to a monophyletic group containing all species of Hyoscyamus and Archihyoscyamus previously described. Conclusions Both the morphological observations and molecular phylogenetic analyses support the recognition of Hyoscyamus labiatus as a new species. Our study also showed that Archihyoscyamus should be a synonym of Hyoscyamus. The delimitation of Hyoscyamus is thus revised in our study.
