A new species, Ainsliaea polystachya X. X. Su & M. J. Zhang is described from Fujian, China, based on morphological traits and molecular markers. The new species is distinct by open panicles, capitula bearing only one flower, and actinomorphic corolla. Keys to the morphologically similar species and phylogenetic allies are proposed.

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 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.

Amanita fense is described and illustrated as a new species from China based on morphological and molecular evidence. This fungus is mainly distributed in the eastern, northeastern and southwestern regions of China, such as Anhui, Liaoning, and Yunnan. It is characterized by medium-sized basidiomata, a buff to cacao brown pileus with long-striate pileus margin, pinkish lamellae, and ellipsoid to elongate inamyloid spores. This is the fifth taxon with pink lamellae within Amanita section Caesareae. We provide a comparison with similar species and a key to those taxa that have pink to pinkish gills in this section.

A new species of Sobralia from Colombia is described and illustrated. Based on morphological and molecular evidence, it is classified under the type section of the genus. The new species is unique among the other species of the genus by its greenish, fleshy sepals and strongly recurvate ovary that determines the downward orientation of the flowers. Additionally, the sepals and petals are not reflexed, making the flower appearance much more slender and less open than in the other species of the section. As there are no other morphologically similar species within the section, the discussion is based on a comparison of the new taxon against its closest relatives according to our phylogenetic results inferred from ITS and matK regions.

Ceropegia chuakulii is a new species from eastern Thailand. Illustrations, photographs and comparison of diagnostic characters to the morphologically similar species, C. acicularis Kidyoo are provided. These two species are characterized by erect stems, needle-like leaves, one–flowered sessile inflorescences and spathulate corolla lobes that are connate at tips. Ceropegia chuakulii is, however, clearly distinguished from C. acicularis by its ovoid to globose corolla tube, corolla lobes being as long as corolla tube, deeply bifid interstamial corona lobes with triangular-lanceolate segments. In addition, the analyses of quantitative morphological traits of flowers also strongly supported the distinctiveness of the new species.

A new species of freshwater crab of the genus Sudanonautes Bott, 1955, is described from the tropical rainforests of Edea and Tiko in southern Cameroon, Central Africa. Sudanonautes tiko n. sp. is recognized by a unique combination of characters of the carapace, thoracic sternum, chelipeds, and male first gonopod, and by distinct mtDNA sequences for two loci (COI and 16S rRNA). A diagnosis, illustrations, and a tree of phylogenetic relationships based on mtDNA sequences are provided, along with a comparison to similar species from the region. Brief notes are provided on the ecology of the new species and of three other species of Sudanonautes collected during this study.

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.

A new species, Phylloporia lespedezae, is described from Shanxi Province on the basis of morphological, ecological characters and molecular evidence. It is characterized by having an annual, pileate basidiocarps with wavy edge, duplex context separated by a black line, a monomitic hyphal system with simple septate generative hyphae, the presence of fusoid cystidioles, yellowish, broadly ellipsoid, thick-walled basidiospores, and growing on Lespedeza (Fabaceae) only. Phylogenetic analysis based on nuclear large subunit ribosomal DNA (nLSU) strongly support P. lespedezae as a distinct species within the genus of Phylloporia. Detailed description with illustration is provided for the new species and its relationships with similar species are discussed. In addition, a key to all 41 species of Phylloporia is provided.

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.

Amanita cingulata, a new species of Amanita sect. Vaginatae with an annulus on the stipe is described based on morphological and molecular evidence. This species was found in forests dominated by members of Fagaceae and/or Pinaceae and is characterized by its small basidioma with a white pileus covered with white and lumpy volval remnants, a pileal margin with short striations, a white fragile annulus, a weak and easily broken lumpy volva on the stipe base and ellipsoid to elongate basidiospores measuring 9–11.5 × 5.5–7 μm. The new species is compared with similar species, especially the annulate taxa of A. sect. Vaginatae.
