A species with an annulus is rare within Amanita section Vaginatae. In this study, A. annulata is proposed as a new species based on morphological and molecular evidence. It is the second annulate species of the section in China, the first being A. cingulata. The new species is found in forests dominated by Fagaceae in Yunnan Province of China. It is characterized by its large basidioma, white pileus covered with large, white, dingy yellow-tipped pyramidal warts that break off easily, a stipe with a mealy, evanescent, white annulus, the base of the stipe covered with concolorous pyramidal warts, and broadly ellipsoid to ellipsoid basidiospores measuring 11−15 × 9−12 μm. Moreover, it is compared with similar species, especially the annulate taxa of Amanita section Vaginatae.

A new species, Inonotus castanopsidis, is described from southwestern China on the basis of morphological characteristics and molecular evidence. It is characterized by having a perennial and resupinate to effused-reflected basidiomata with greyish yellow to lavender pore surface, a monomitic hyphal system with simple-septate generative hyphae, which are rarely branched, presence of both hyphoid and hymenial setae, and ellipsoid to subglobose, yellowish, thick-walled basidiospores. Detailed description with illustration is provided for the new species and its relationships with similar species are discussed.

A new species Mensularia rhododendri is described from southwestern China on the basis of both morphological characters and molecular evidence. Phylogenetic analysis based on nuclear large subunit (nLSU) ribosomal RNA gene shows that the new species belongs to Mensularia. Morphologically, the new species is mostly similar to Mensularia hastifera by sharing similar hymenial setae and basidiospores in shape and size. However, M. rhododendri differs in smaller pores (5–6 per mm), thinner fruit body (up to 2.5 mm), shorter and unbranched hyphoid setae (up to 110 µm long) present in trama only, basidiospores not collapsed, and growth on Rhododendron in nearly the timber line of southwest China, while M. hastifera has relatively larger pores (3–4 per mm), thicker fruit body (up to 10 mm), longer and sometimes branched hyphoid setae (up to 300 µm long) frequently present in both trama and dissepiments, and mostly collapsed basidiospores, and occurs mostly on Fagus in the temperate area of Central Europe. The morphological differences between M. rhododendri and other similar species of Mensularia are also compared.

Habenaria luquanensis from Yunnan Province is described and illustrated. This new species most closely resembles H. delavayi in having a basal leaf rosette, flowers with a concave and abaxially keeled dorsal sepal and linear petals. It is distinguished by herbaceous, loosely arranged rosette leaves (versus tightly adpressed to each other), a lip which is 3-lobed only to 1/3–1/4 from the base and has narrowly oblong lateral lobes (versus deeply 3-lobed nearly to the base with linear-cuneate lateral lobes). Another similar species is H. finetiana, but this species can be distinguished by its cauline leaves, longer floral bracts, petals forming a hood with the dorsal sepal, a lip which is 3-lobed only in the upper half and  rhombic, serrate lateral lobes, a spur which is nearly as long as the ovary, and central rostellum lobe not clearly visible.

A new species of the genus Nemoura, N. latilongispina sp. nov. from Chuxiong Yi Autonomous Prefecture of Yunnan Province, southwestern China is described and illustrated. The new species is characterized by ventral sclerite of epiproct extended laterally, forming upcurved plates fringed with long spines along upper margin, and by the strongly sclerotized, fork-shaped cercus.

Begonia yizhouensis, a new species in Begonia sect. Coelocentrum (Begoniaceae) from Guangxi of China, is described and illustrated. Morphologically, it is similar to the adjacently distributed B. luochengensis, but clearly separated by its waxy leaves with glabrous or sometimes sparsely puberulous surfaces, larger variation in leaf color and maculation along the main veins, white to pinkish-white flowers and late flowering. Furthermore, molecular phylogenetic analysis indicated B. yizhouensis was a monophyletic lineage and was sister with B. luochengensis. The relationship of the new species and other similar species is also discussed. This new species is endemic to limestone hills in Guangxi and is assessed as “Endangered” (EN) according to the IUCN Red List Categories and Criteria. Additionally, morphological and molecular evidence for B. yishanensis not being synonymous with B. porteri is presented.

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.

Abstract Southeastern Asia has been postulated as probably the original sites of genus Haemaphysalis, where numerous structurally advanced haemaphysalids now occur. Because of its phylogenetic and biological interest, we report the discovery of a structurally primitive new species Haemaphysalis (A.) kolonini belonging to subgenus Alloceraea from Baoshan and Weixi cities, Yunnan province, southwestern China. Both the morphological and phylogenic characteristics of the species support congruently to erect Hae. (A.) kolonini as a new species. The male and female adults of Haemaphysalis (A.) kolonini are respectively described and illustrated. Taxonomic discussion and keys to Alloceraea species in China are also provided to be able to distinguish species that are close morphologically.

A new species of the Lethe trimacula-group, viz. L. langsongyuni sp. nov. is described from Weixi County, representing the third member of this species group in northwestern part of Yunnan Province, southwestern China. In general L. langsongyuni sp. nov. is closely related to L. liae Huang, 2002, L. proxima Leech, 1892 and L. umedai albofasciata Huang, 2002, but it can be distinguished from all of them by combination of several details in wing pattern and male genitalia. The adults and male genitalia of the species aforementioned are illustrated.

Two specimens of Hypoxylon were collected from Yunnan, southwestern China. Hypoxylon baihualingense, an undescribed species of Hypoxylon (Xylariales, Hypoxylaceae), is described and illustrated as a new species based on a combination of morphological and phylogenetic (ITS and β-tubulin sequences) data. The new species is characterized by its glomerate to pulvinate stromata with ostiolar discs and asci lacking an apical apparatus. The differences between the new species and some morphologically similar Hypoxylon species are discussed. Hypoxylon polyporoideum is reported as a new record from China.
