Two new Xeromphalina species with eccentric stipes are described from subtropical China. Xeromphalina brevipes sp. nov. is characterized by a pileus without a depressed centre, a rather short stipe, cylindrical basidiospores, and subcoralloid to coralloid circumcystidia and caulocystidia. Xeromphalina utricularis sp. nov. can be distinguished by its small and cylindrical basidiospores, utriform cystidia and its growth habit on rotten Pinus densata Mast. wood in the montane zone. Photographs and illustrations of the basidiomata and morphological features of these species are presented. Morphological characters, when compared with related Xeromphalina species, and phylogenetic analyses based on internal transcribed spacer sequences with Maximum Likelihood and Bayesian Inference, demonstrate that the two new taxa are different from related Xeromphalina species.

A New Species

Tubaria squamata is described as new from Jiaohe county, Jilin province, China. This species is distinctive morphologically because of the small (slightly) hairy or scaly pileus, subelliptic to elliptic non-amyloid basidiospores, subclavate to cylindrical or lageniform cheilocystidia, and a pileipellis as a cutis. Phylogenetic analyses based on internal transcribed spacer sequences with Bayesian Inference analysis (BA) and Maximum Likelihood (ML) showed that T. squamata is different from related species. Illustrations and a complete taxonomic description are also provided, as well as a key to the Tubaria species known from China.

Gerronema indigoticum sp. nov., distinctive for its blue to blue-green basidiomata, is described as a new taxon from subtropical China. Photographs of basidiomata, morphological features and relevant illustrations of this species are presented. Morphological characters compared with related Gerronema species and phylogenetic analyses conducted based on the internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences with Maximum Likelihood (ML) and Bayesian Analysis (BA) tree show that the new taxon can be distinguished from phenotypically similar and phylogenetically related species.

Two new species, Xylodon bambusinus and X. xinpingensis, are proposed based on morphological and molecular evidences. Both species share the annual growth habit, resupinate basidiomata and monomitic hyphal system with clamped, colorless generative hyphae, smooth, thin-walled basidiospores, but X. bambusinus is characterized by the smooth to tuberculate hymenial surface, presence of capitate and fusiform cystidia, broad ellipsoid basidiospores, while X. xinpingensis by the reticulate hymenophore with cream hymenial surface, and subglobose basidiospores (4.5–6 × 3.5–5 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS+nLSU sequences showed that X. bambusinus was sister to X. subclavatus, while X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus. The nLSU dataset revealed that X. bambusinus grouped with X. asperus and X. brevisetus with lower supports, and that X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus and then with X. rimosissimus without supports. Both morphological and molecular evidences confirmed the placement of two new species in Xylodon. Description and figures from the new species and a key to the known species of Xylodon from China are presented.

A new wood-inhabiting fungal species, Gloeodontia yunnanensis, is proposed based on a combination of morphological features and DNA data. The species is characterized by an annual, resupinate basidiomata with smooth hymenial surface, a monomitic hyphal system with thin-walled, clamped generative hyphae and obclavate cystidia and subglobose to globose, hyaline, thick-walled, asperulate, strongly amyloid, acyanophilous basidiospores measuring 3.3–4.3 × 2.5–3.5 µm. Sequences of ITS and 28S gene regions of the studied samples were generated and phylogenetic analyses were performed with Maximum Likelihood, Maximum Parsimony and Bayesian Inference methods. The analyses based on ITS+28S sequences showed that G. yunnanensis nested in the Gloeodontia clade and formed a monophyletic lineage with strong support (100% BS, 100% BP, 1.00 BPP).

In this paper, Claviformisporagen. nov. in Linocarpaceae is introduced from Phyllostachys heteroclada in Sichuan Province, China. The new genus is characterised by its distinct morphological characters, such as ostiole with periphyses, asci with a thick doughnut-shaped, J- apical ring and clavate ascospore without septum-like band and appendage. Maximum Likelihood and Bayesian Inference phylogenetic analyses, based on DNA sequence data from ITS, LSU, SSU and TEF-1α regions, provide further evidence that the fungus is a distinct genus within this family. The new genus is compared with similar genera, such as Linocarpon and Neolinocarpon. Descriptions, illustrations and notes are provided for the new taxon.

Wood-inhabiting fungi play a significant role in wood degradation and the cycle of matter in the ecological system. In the present study, three new wood-inhabiting fungal species, Trechispora bambusicola, Trechispora fimbriata, and Trechispora fissurata spp. nov., are nested in Trechispora, which are proposed based on a combination of morphological features and molecular evidence. Sequences of internal transcribed spacer (ITS) and large subunit (nLSU) regions of the studied samples were generated, and the phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic analyses inferred from ITS showed that T. bambusicola was sister to Trechispora stevensonii, T. fimbriata grouped with Trechispora nivea, and T. fissurata grouped with Trechispora echinospora. The phylogenetic tree based on ITS + nLSU sequences demonstrated that T. bambusicola formed a single lineage and then grouped with Trechispora rigida and T. stevensonii. T. fimbriata was sister to T. nivea. T. fissurata grouped with Trechispora thelephora.

A New Species

The Adiantum pedatum complex is disjunctly distributed in North America and eastern Asia. In this study, we carried out a detailed morphological study based on 137 specimens representing the biogeographic diversity of this complex. The sequences of eight chloroplast markers of 35 samples were analyzed with maximum likelihood and Bayesian inference. The morphological and phylogenetic analyses support the recognition of a new species of the A. pedatum complex from Japan. We propose the new species as A. japonicum based on the examinations of specimens from Japan and the comparative analyses of the whole complex. This new species can be distinguished from A. pedatum by the erect rhizome and shows significant molecular differences from other species in this complex. A taxonomic description with detailed morphological characters of the new species is presented.

AbstractTapeworms of the family Gryporhynchidae are endoparasites of fish-eating birds distributed worldwide. Currently the family contains 16 genera classified on the basis of the morphology of the rostellar apparatus, rostellar hooks and strobilar anatomy. However, the phylogenetic relationships among the genera are still unknown. In this study, sequences of the near complete 18S (SSU) and 28S (LSU) from rDNA of 13 species of gryporhynchids (adult specimens) representing eight genera (Cyclustera, Dendrouterina, Glossocercus, Gryporhynchidae gen. sp., Neovalipora, Paradilepis, Parvitaenia, Valipora) and one species of metacestode from fish (Neovalipora) were generated. Additionally, sequences of metacestodes of the genera Amirthalingamia, Neogryporhynchus, Paradilepis, Parvitaenia and Valipora from Africa recently added to the GenBank database were analysed. Phylogenetic relationships were inferred using maximum-likelihood (ML) and Bayesian inference of each (SSU and LSU) dataset. The phylogenetic analyses indicated that the family Gryporhynchidae is a well-supported monophyletic group within the Cyclophyllidea. The trees inferred with SSU and LSU datasets had similar topologies and suggested that the genera Glossocercus (two species sequenced) and Paradilepis (four spp.) are monophyletic. In contrast, Dendrouterina, Parvitaenia and Valipora are paraphyletic, suggesting that the species composition of these genera should be critically reviewed. Interestingly, species of the genera that use the same groups of definitive hosts such as herons (Ardeidae), cormorants (Phalacrocoracidae) and ibis (Threskiornithidae) are together in the phylogenetic tree, even though they differ markedly from each other in some morphological characters, especially shape and size of rostellar hooks.
