A new wood-inhabiting fungus, Phlebia nigrodontea, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by a grandinioid hymenophore with vinaceous brown to black colour, a monomitic hyphal system with clamped generative hyphae and ellipsoid, colourless, thin-walled, smooth basidiospores (3.9–4.9 × 2.3–3.1 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses carried out using maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on the molecular data of ITS+nLSU sequences showed that P. nigrodontea nested within the phlebioid clade. A further investigation of more representative taxa from Phlebia, based on ITS+nLSU sequences, demonstrated that the species P. nigrodontea formed a monophyletic lineage with strong support (100% BS, 100% BT, 1.00 BPP) and closely grouped with P. chrysocreas.

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.

Two new corticioid fungal species, Phanerochaete pruinosa and P. rhizomorpha spp. nov. are proposed based on a combination of morphological features and molecular evidence. Phanerochaete pruinosa is characterized by the resupinate basidiomata with the pruinose hymenial surface, a monomitic hyphal system with simple-septate generative hyphae and subcylindrical basidiospores measuring as 3.5–6.7 × 1.5–2.7 µm. Phanerochaete rhizomorpha is characterized by having a smooth hymenophore covered by orange hymenial surface, the presence of rhizomorphs, subulate cystidia, and narrower ellipsoid to ellipsoid basidiospores. Sequences of ITS+nLSU nrRNA gene regions of the studied specimens were generated and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that two new species clustered into genus Phanerochaete, in which P. pruinosa was sister to P. yunnanensis with high supports (100% BS, 100% BT, 1.00 BPP); morphologically differing by a pale orange to greyish orange and densely cracked hymenial surface. Another species P. rhizomorpha was closely grouped with P. citrinosanguinea with lower supports; morphologically having yellow to reddish yellow hymenial surface, and smaller cystidia measuring as 31–48 × 2.3–4.8 µm.

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.

The systematic position of Pterogonidium pulchellum (W.J. Hooker) Muell. Hal. in the Sematophyllaceae and Piloecium pseudorufescens (Hampe) Muell. Hal. in the Myuriaceae is reexamined with new evidence derived from rbcL gene sequences. A total of 18 taxa from Sematophyllaceae, Hypnaceae, Myuriaceae, and Hookeriaceae were included, 11 of which were newly sequenced for the rbcL gene. Analyses were done using maximum parsimony, maximum likelihood (TrN + Γ + I model and GTR + Γ + I model), and Bayesian inference (GTR + Γ + I model). The results show that Pterogonidium pulchellum has a closer relationship with members of Hypnaceae than with Sematophyllaceae, while Piloecium pseudorufescens forms a clade with the Sematophyllaceae in all phylogenetic analyses, with robust branch support. Two SOWH tests were carried out and the results show that it is not appropriate to classify Pterogonidium pulchellum in Sematophyllaceae and it is also not appropriate to classify Piloecium pseudorufescens in Myuriaceae.

Distinct Genus

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.

A New Species

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

Phylogenetic Data

The genus Lamproconium comprises species that are endophytes, saprobes and pathogens on a wide variety of plants. This genus is currently placed in Diaporthales genera incertae sedis. Fresh specimens of Lamproconium were collected in Russia and studied to provide morphological and phylogenetic data. Phylogenetic analyses of single spore isolates generated from maximum likelihood, maximum parsimony and Bayesian inference analyses using combined ITS and LSU sequence data, place L. desmazieri in the order Diaporthales. Melanconis desmazieri is synonymized under Lamproconium desmazieri, and Lamproconiaceae is introduced as a new family to accommodate L. desmazieri and Hercospora tiliae, based on morphology and phylogenetic analyses.
