A New Species

Phylloporia moricola is described as a new species based on collections from Sichuan Province, China. All studied basidiocarps grow on trunks of Morus sp. This new species is supported by morphological features and phylogenetic analyses of DNA sequences inferred from a dataset of nuc 28S rDNA. P. moricola is characterized by having effused-reflexed to pileate basidiocarps, pores 7–9 per mm, duplex context with a black line when young, dimitic hyphal system, and brownish, slightly thick-walled basidiospores generally measuring 3.4–4 × 2.7–3.2 μm. Phylloporia moricola is phylogenetically most closely related to Phylloporia mori, that also occurs on Morus sp., but that species differs from P. moricola in having hymenial setae and larger basidiospores (4–4.8 × 3.1–3.8 μm).

A New Species

A new wood-rotting fungal species, Punctularia bambusicola, is proposed based on a combination of morphological features and molecular data. The species is characterized by resupinate, lilac to purple basidiomata, pink to rose tuberculate hymenial surface, monomitic hyphal system with clamped generative hyphae, yellowish to brown dendrohyphidia and ellipsoid basidiospores measuring 6.5–8.5 × 3.5–5 µm. Phylogenetic analyses of combining ITS and LSU nrRNA gene regions demonstrated that P. bambusicola forms a single lineage sister to P. atropurpurascens with strong statistical supports (100% BS, 100% BT, 1.00 BPP).

During an investigation of fungicolous fungi associated with mushrooms in China, four boleticolous fungi were collected from Sichuan Province. Based on the morphological features and multi-gene phylogenetic analyses this study introduces two new species, Hypomyces ampullaris, and H. sichuanensis. The new species are described and illustrated comprehensively and compared with their related fungi. Hypomyces ampullaris is similar to Sepedonium ampullosporum in forming candelabrum-like conidiophores and producing ampulliform conidia but differs from the latter in having shorter phialides and smaller ampulloconidia. Hypomyces sichuanensis is similar to H. chrysospermus, H. microspermus, and Sepedonium laevigatum in forming poorly developed verticills conidiophores and the shape and size of aleurioconidia. However, the asexual spores of H. sichuanensis averaged somewhat smaller than those of H. chrysospermus and S. laevigatum, and larger than that of H. microspermus. Additionally, H. ampullaris and H. sichuanensis distinct from their close relatives in no pigment discoloration of the PDA medium. These species introduced here, improve our understanding of the diversity of Hypomyces, especially of the boleticolous Hypomyces in China.

A New Species

Based on molecular phylogenetic analyses and morphological characters, a new species from Bangladesh, northern Vietnam, and southwestern China, Leptolejeunea nigra, is described. It is mostly similar to L. balansae but remarkable for having brownish black ocelli in its leaf lobes. In the molecular phylogeny, the samples of L. nigra are not nested within any clade and form an independent lineage. In particular, the molecular dating suggested that the divergence of L. nigra happened in time span of the formation of the Himalayas.

Two taxa of Coprinellus from China are described on the basis of morphological features and phylogeny. Coprinellus pseudodisseminatus is described as a new species in Coprinellus section Setulosi due to its milky-white to pale-grey pileus, lageniform caulocystidia, the presence of pileocystidia and cheilocystidia, and ellipsoid basidiospores. Coprinellus aureogranulatus, belonging to section Micacei, is new to China. Phylogenetic analyses based on ITS sequences by the Maximum Likelihood and Bayesian methods showed that C. pseudodisseminatus and C. aureogranulatus are a new and newly recorded species, respectively. Illustrations, photographs, and detailed descriptions of the two species are provided.

Abstract Background The Tibetan antelope Pantholops hodgsonii (Abel) (Artiodactyla: Bovidae) is an endangered species of mammal endemic to the Qinghai-Tibetan Plateau. Parasites and parasitic diseases are considered to be important threats in the conservation of the Tibetan antelope. However, our present knowledge of the composition of the parasites of the Tibetan antelope remains limited. Methods Large numbers of nematode parasites were collected from a dead Tibetan antelope. The morphology of these nematode specimens was observed using light and scanning electron microscopy. The nuclear and mitochondrial DNA sequences, i.e. small subunit ribosomal DNA (18S), large subunit ribosomal DNA (28S), internal transcribed spacer (ITS) and cytochrome c oxidase subunit 1 (cox1), were amplified and sequenced for molecular identification. Moreover, phylogenetic analyses were performed using maximum likelihood (ML) inference based on 28S and 18S + 28S + cox1 sequence data, respectively, in order to clarify the systematic status of these nematodes. Results Integrated morphological and genetic evidence reveals these nematode specimens to be a new species of pinworm Skrjabinema longicaudatum (Oxyurida: Oxyuridae). There was no intraspecific nucleotide variation between different individuals of S. longicaudatum n. sp. in the partial 18S, 28S, ITS and cox1 sequences. However, a high level of nucleotide divergence was revealed between the new species and its congeners in 28S (8.36%) and ITS (20.3–23.7%) regions, respectively. Molecular phylogenetic results suggest that the genus Skrjabinema should belong to the subfamily Oxyurinae (Oxyuroidea: Oxyuridae), instead of the subfamily Syphaciidae or Skrjabinemiinae in the traditional classification, as it formed a sister relationship to the genus Oxyuris. Conclusions A new species of pinworm Skrjabinema longicaudatum n. sp. (Oxyurida: Oxyuridae) is described. Skrjabinema longicaudatum n. sp. represents the first species of Oxyurida (pinworm) and the fourth nematode species reported from the Tibetan antelope. Our results contribute to the knowledge of the species diversity of parasites from the Tibetan antelope, and clarify the systematic position of the genus Skrjabinema.

A New Species

Species of Raffaelea (Ophiostomatales: Ascomycota) are obligate symbionts of ambrosia beetles, some of which pose a substantial threat to forest trees. Leucaena leucocephala is a small mimosoid tree species that is considered as an invasive weed in most of its introduced range globally. During a field expedition on the French island of Réunion, dying L. leucocephala trees were observed. Samples were taken from these trees and isolations made from symptomatic wood tissues that included beetle tunnels, but in the absence of the beetles themselves. Multiple isolates of a fungus resembling a Raffaelea species were obtained from the discoloured wood associated with the beetle tunnels. To determine their identity, microscopic examination was performed and DNA sequences for three gene regions (ITS, LSU, TUB) were obtained. Phylogenetic analyses based on these gene regions revealed that the isolates represent a new species of Raffaelea, described here as R. borbonica sp. nov. A pathogenicity test was conducted with the fungus, which was shown to cause lesions on the inoculated seedlings, but with a low level of aggressiveness.

A new species of Fistulina, F. tasmanica sp. nov., is described and illustrated from Tasmania in Australia. Fistulina tasmanica is distinguished by its pileate and fleshy basidiomata with rose pore surface, fibrous context, separated tubes with small pores (6–7 per mm), a monomitic hyphal system with only clamped generative hyphae, subellipsoid to ellipsoid basidiospores (5.4–6 × 3.4–4 μm) which are negative in Melzer’s reagent and cotton blue. Phylogenetic analyses inferred from the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU) sequences also confirmed that F. tasmanica is a new member within Fistulina.

A New Species

The hero shrew's ( Scutisorex somereni ) massive interlocking lumbar vertebrae represent the most extreme modification of the vertebral column known in mammals. No intermediate form of this remarkable morphology is known, nor is there any convincing theory to explain its functional significance. We document a new species in the heretofore monotypic genus Scutisorex ; the new species possesses cranial and vertebral features representing intermediate character states between S. somereni and other shrews. Phylogenetic analyses of DNA sequences support a sister relationship between the new species and S. somereni . While the function of the unusual spine in Scutisorex is unknown, it gives these small animals incredible vertebral strength. Based on field observations, we hypothesize that the unique vertebral column is an adaptation allowing these shrews to lever heavy or compressive objects to access concentrated food resources inaccessible to other animals.
