A New Species

Saxifraga shennongii L. Wang, W.B. Liao et J. J. Zhang, a new species of Saxifragaceae from Hunan, China, is described and illustrated. The new species belongs to genus Saxifraga sect. Irregulares and can be distinguished from other species by stolons absent, basal leaf blade subrounded and abaxially spotted, absence of foliar embryos in the sinus, petiole sparsely short glandular pilose or glabrous and inflorescence branches up to 10 cm long. Phylogenetic analysis based on four chloroplast DNA regions (rbcL, psbA-trnH, matK and psaJ-rpl33) confirmed that the new species differed from those similar species of Saxifraga sect. Irregulares. The new species is similar to S. daqiaoensis and S. mengtzeana, but differs in indumentum and the shape of leaf.

Rehderodendron truongsonense, a new species from Vietnam, is described and illustrated. In the treatment of the Styracaceae for the Flore du Cambodge, du Laos, et du Viêtnam, specimens of this species were recognized as R. macrocarpum Hu. These specimens clearly differ from R. macrocarpum, however, as well as from all other species of Rehderodendron (where these characters are known) by, e.g., an evergreen versus deciduous habit, fewer secondary veins of the leaf blade, shorter inflorescences and corolla lobes, large and conspicuous lowermost bracteoles, the presence of eight ovules per carpel, and a fruit with ca. 10 to 20 ribs that are indistinct. Phylogenetic analysis based on five chloroplast DNA regions (clpP-psbB, ndhD-psaC-ndhE-ndhG, rpl22-rps19, rps18-rpl20, and psbI-trnS-GCU) placed the new species as nested within Rehderodendron and sister to R. gongshanense. This new species is endemic to the Truong Son Mountain Range, from which the epithet is derived, and we assign it an IUCN Red List preliminary status as Near Threatened.

A New Species

A new species, Ophiocordyceps ramosissimumsp. nov., is described and illustrated. It was associated with larvae of Phassus nodus (Hepialidae) collected from Xuefeng Mountains, Hunan Province, China. It differs from similar species in having branched stromata without a sterile apex, superficial ascomata, and very wide asci and ascospores and in its occurrence on Phassus nodus in living roots or trunks of Clerodendrum cyrtophyllum. Multi-gene phylogenetic analysis of 5.8S-ITS rDNA, nrSSU, EF-1α, and RPB1 gene loci also confirmed the distinctiveness of this new species.

A New Species

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A New Species

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.

The genus Protubera includes gasteroid species. Its members are globally distributed in tropical, subtropical, and temperate areas, and presently, six species are recognized. In this paper, Protubera beijingensis from North China is described as a new species. Its morphological description and illustration are provided in detail and compared with morphologically similar species. A multigene phylogenetic analysis based on nLSU, atp6, and rpb2 sequences of the genus Protubera also identifies this organism as a new species within Protubera.

During a survey of araneogenous fungi from Guizhou Province, China, a new species, Akanthomyces araneogenum, was isolated from a spider, Araneus sp. It differs from other Akanthomyces species by its spider host, Isaria-like conidiogenous structure, and mostly globose and smaller conidia (1.6–2.2 μm). Multi-locus (ITS, LSU, RPB1, RPB2 and TEF) phylogenetic analysis confirmed that A. araneogenum is distinct from other species. The new species is formally described and illustrated, and compared with similar species.

A New Species

Chrysanthemum bizarre (Asteraceae), a new species from Hunan Province, China, is described and illustrated. It is similar to Chrysanthemum vestitum in that its leaves are pubescent, and the ray florets are white. However, it differs from C. vestitum in that the abaxial pubescence of C. bizarre (6.5%) is much more sparsely appressed than that of C. vestitum (64.9%). The leaf blade is triangular ovate with its base extending downward on both sides of petiole to form wings. Only one capitulum, of which the outmost phyllaries are leaflike, develops at the tip of every flowering scape rather than forming an unconsolidated cyme synflorescence. In addition, the lectotype of C. vestitum was designated in this study.

A New Species

Begonia leipingensis D. K. Tian, L. H. Yang & C. Li (2n = 30), a new species in Begonia sect. Coelocentrum from the limestone area of Guangxi, China. B. leipingensisis is easily distinguished from any other compound-leaved species in Begonia by its large variation in petiolule number and its unique spirally-arranged petiolule pattern, which has never been seen in Begoniaceae before and rarely seen even in other angiosperm taxa. Besides having non-overlapping flowering periods, it is clearly different from B. fangii, the most morphologically similar species in the same section and with the same chromosome number. In addition to its unique petiolule pattern, B. leipingensis has longer abaxial wings, shorter internodes, and usually larger leaves, leaflets and habit. Molecular phylogenetic analysis showed that B. leipingensis formed an independent lineage belonging to Sect. Coelocentrum. Morphological and phylogenetic evidence strongly supports this species as a new taxon in Sect. Coelocentrum of Begonia. B. leipingensis was assessed to be critically endangered based on criterion outlined by IUCN Red List Categories and Criteria.

Inocybe griseorubida sp. nov. is described from Kerala State, India. A comprehensive description, photographs, and comparisons with phenetically similar species are provided. The nuclear ribosomal internal transcribed spacer region (ITS), a portion of the nuclear ribosomal large subunit (nLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (rpb2) gene of this species were sequenced and analyzed. Phylogenetic analysis of rpb2 sequences confirmed both the novelty of the species and its placement within the Pseudosperma clade.
