A New Species

Lactarius sect. Deliciosi includes a group of edible mushrooms with a worldwide geographical distribution. Although several species are considered choice edible mushrooms, taxonomic knowledge on this group in Asia is still fragmentary. A new species in L. sect. Deliciosi with orange latex, L. vividus, is described as an important wild edible mushroom that is widely distributed in central and southern China. Morphological analyses demonstrate that L. vividus encompasses high infraspecific morphological variation, which makes it difficult to clearly delimit its taxonomic boundary. Compared with other species having orange latex in L. sect. Deliciosi, L. vividus can be recognized by the vividly colored, subdistant to distant lamellae and heavy basidiospore ornamentation. It has been found to grow with four species of Pinus subg. Pinus including P. latteri, P. massoniana, P. taiwanensis and P. thunbergii. Phylogenetic analyses of the ITS region and glyceraldehyde-3-phophate dehydrogenase gene (gpd) support species delimitation and suggest ITS and gpd are good DNA markers to identify this new species.

A New Species

Lactarius sect. Deliciosi is a group of ectomycorrhizal mushrooms showing high host specificity with trees of Pinaceae and more rarely Fagales. A new species of this section, L. guangdongensis, is described from South China. This new species has the smallest basidiocarps (pileus 1–3 cm) in the section. The pure orange basidiocarps with faint greenish discoloration are similar to those of Abies-associated L. abieticola and L. laeticolor and Pinus-associated L. vividus. The subdistant lamellae and absence of pleuromacrocystidia can be used as valid characters for this species. It grows with Chinese national protected plant Pinus kwangtungensis and might be one of the very few species that form symbiosis with five-needle pines. Phylogenetic analyses of the ITS region and glyceraldehyde-3-phosphate dehydrogenase gene (gpd) show that L. guangdongensis clearly diversified from its relatives and look-alikes and probably represents an early diverging lineage in the section. Molecular and morphological characters provided in this study will be useful for in situ and ex situ conservation of P. kwangtungensis in the future.

A New Species

A new species of colubrid snake, Lycodon cathayasp. nov., is described based on two adult male specimens collected from Huaping Nature Reserve, Guangxi, southern China. In a phylogenetic analyses, the new species is shown to be a sister taxon to the clade composed of L. futsingensis and L. namdongensis with low statistical support, and can be distinguished from all known congeners by the significant genetic divergence in the mitochondrial cytochrome b gene fragment (p-distance ≥ 7.9%), and morphologically by the following combination of characters: (1) dorsal scales in 17–17–15 rows, smooth throughout; (2) supralabials eight, third to fifth in contact with eye, infralabials nine; (3) ventral scales 199–200 (plus two preventral scales), subcaudals 78; (4) loreal single, elongated, in contact with eye or not, not in contact with internasals; (5) a single preocular not in contact with frontal, supraocular in contact with prefrontal, two postoculars; (6) maxillary teeth 10 (4+2+2+2); (7) two anterior temporals, three posterior temporals; (8) precloacal plate entire; (9) ground color from head to tail brownish black, with 31–35 dusty rose bands on body trunk, 13–16 on tail; (10) bands in 1–2 vertebral scales broad in minimum width; (11) bands separate ground color into brownish black ellipse patches arranged in a row along the top of body and tail; (12) elliptical patches in 3–6 scales of the vertebral row in maximum width; (13) ventral surface of body with wide brownish black strip, margined with a pair of continuous narrow greyish white ventrolateral lines. With the description of the new species, 64 congeners are currently known in the genus Lycodon, with 16 species occurring in China.

A New Species

The Asian frog genus Megophrys is a diverse group of morphologically conserved, forest-dwelling frogs. The genus harbours highly localised species diversification and new species continue to be described on a regular basis. We examined the taxonomic status of a population of Megophrys frogs from the Hoang Lien Range in northern Vietnam and southern China previously identified as M. kuatunensis (subgenus Panophrys). Preliminary phylogenetic analyses using a fragment of 16S rDNA places the species in question within the Megophrys (subgenus Panophrys) species group, a primarily Chinese radiation within the genus. On the basis of morphological, molecular and bioacoustic data, we conclude that this population does not represent M. kuatunensis, or any known species in the genus. We herein describe this species of Megophrys as new. Known only from Sa Pa District, Lao Cai Province in Vietnam and Jinping County, Yunnan Province in China, the new species is likely to be threatened by ongoing deforestation in the region. We provide an updated species description of M. kuatunensis based on type specimens, and suggest that M. kuatunensis is likely to be restricted to eastern China.

Based on morphological and molecular phylogenetic studies, Semiaquilegia danxiashanensis, a new species from Danxia Shan in northern Guangdong, southern China, is described and illustrated. This species is easily distinguishable from each of other three known species in the genus by characters of the flowers and fruits. In addition, molecular phylogenetic analyses of both the nuclear ITS and the plastid trnL-F region strongly supported S. danxiashanensis as a separate species from other species of Semiaquilegia. We provide a detailed morphological and habitat description, distribution, as well as colour photographs and illustrations of the new species.

A New Species

Heimioporus sinensis, collected from tropical and subtropical areas of China, is introduced as a new species based on both morphological characters and molecular data. The species is characterized by the purplish red to deep magenta pileus, the reticulated stipe, the irregularly reticulate to reticulate-alveolate basidiospores 11.5–13.5 × 8–9.5 μm, and a trichodermal to intricately trichodermal pileipellis. Phylogenetic analyses based on the nuc 28S rDNA D1-D2 domains (28S) and the translation elongation factor 1-α gene (tef1-α) showed that H. sinensis is a distinct member of the genus Heimioporus in the subfamily Xerocomoideae.

A new species of Asian warty newt, Paramesotriton ermizhaoi, is described from Guangxi Zhuang Autonomous Region in southern China. This species is easily distinguished from other congeners by external morphology and osteology. Phylogenetic analyses based on mitochondrial data place P. ermizhaoi as a possible sister taxon to P. hongkongensis and P. chinensis. The number of trunk vertebrae varies from 12 to 13 in the new species. The relationship between P. ermizhaoi and a potentially new Pachytriton species (Pachytriton C), and the Guangxi population of P. chinensis is briefly discussed.

A New Species

Russula subrutilans sp. nov., a new species of Russula is described from southern China. It is unique for having buff pink to light congo-pink pileus, distant ventricose to subventricose lamellae with rare lamellulae, globose to broadly ellipsoid spores with bluntly conical warts forming a partial reticulum, and narrowly clavate to clavate cheilocystidia and pleurocysitidia with variable tips. Phylogenetic relationships among the new species and other closely related species in the genus are inferred based on the internal transcribed spacer (ITS) region.

Basal Position

During an investigation of the yeast communities associated with wild fruit shrubs in Dagestan (Caucasus, Russia), four fermenting ascospore-producing yeast strains were isolated from leaves of the Georgian honeysuckle (Lonicera iberica M. Bieb.) and from soil underneath this plant. Phylogenetic analyses based on concatenated sequences of the ITS region and D1/D2 domains of the large subunit rRNA gene and concatenated sequences of the ribosomal DNA cystron, RPB2 and TEF1 genes showed that the isolated strains represented a new species of the genus Zygotorulaspora. The new species was placed in the basal position to other species of the clade and close to Zygotorulaspora mrakii. Based on the results of phylogenetic analyses and the phenotypic characteristics of the four studied strains, a novel species is described, for which the name Zygotorulaspora dagestanica sp. nov. is proposed. The holotype is KBP Y-4591T, three metabolically inactive cryopreserved isotype cultures are DSM 100088, VKM Y-3060 and VKPM Y-4318. The MycoBank number is MB 838285.

A New Species

Thelephora austrosinensis is described as a new species from southern China. Morphologically, it is closely related to T. ganbajun and T. vialis but is distinguished by its relatively smaller basidiomata with a thinner and more serrate or lobed margin, obviously longitudinally rugulose hymenial surface, and habitat in the broad-leaved forests. Based on the molecular phylogenetic analyses, sequences of the new species form a distinct clade which is close to T. ganbajun and T. vialis. Detailed morphological descriptions, colour photographs of the new species and comparisons with similar taxa are presented.
