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.

A New Species

Plectania lutea, is described as a new species from subtropical karst areas of China. The main distinguishing characteristics of P. lutea are the yellow hymenium, the external surface with ridges, the gelatinous but not semifluid medullary excipulum, and the large finely warted ascospores. The phylogenetic analyses based on internal transcribed spacer (ITS) and the large subunit (LSU) regions of rDNA sequences using Bayesian (BA) and Maximum Likelihood (ML) methods showed that the new taxon can be distinguished from phenotypically similar and phylogenetically related species.

Fungal Genus

A new poroid wood-inhabiting fungal genus, Rigidotubus, is proposed to accommodate  R. tephroleucus sp. nov. based on morphological characters and molecular evidence. The genus is characterized by tough and poroid basidiomata, white to grayish white pore surface, white sterile margin, a monomitic hyphal system with clamped generative hyphae, ovoid to ellipsoid basidiospores negative in Melzer’s reagent and Cotton Blue. The phylogenetic analyses inferred from the internal transcribed spacer (ITS) and nuclear large subunit (28S) ribosomal RNA gene regions confirmed that Rigidotubus belongs to Cystostereaceae in Agaricales. A key to the accepted genera of Cystostereaceae is provided.

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.

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

Gerhardtia sinensis, as a new species discovered from southern China, is described, illustrated and compared with morphologically similar and phylogenetically related species. Morphologically, it is characterized by its white to yellowish or partially pale yellow pileus with faint striae, subdistant to fairly distant lamellae with intervenose veins, and slightly verruculose basidiospores (4.7–)5.2–6.2(–6.6) × (2.5–)3.0–3.4(–3.8) μm in size. Molecular phylogenetic analyses of the new species and related taxa are performed based on the sequences of nuclear ribosomal large subunit (nrLSU) and nuclear ribosomal internal transcribed spacer (ITS).

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.

Sidera is a polypore genus with white to cream or buff basidiomata, whose species in Hymenochaetales are poorly known. We study the phylogeny and diversity of Sidera based on our recent collections from tropic and subtropic Asian-Pacific regions. Phylogenetic analyses based on the internal transcribed spacer (ITS) and nuclear large subunit (nLSU) ribosomal RNA gene regions indicate that ten terminal lineages are well supported within Sidera. Based on morphological examination and phylogeny, four new species, viz. Sidera minutissima, S. parallela, S. srilankensis and S. tenuis are described, and a new combination, Sidera minutipora, is proposed. All these species are illustrated. Sidera minutissima is characterized by tiny basidiomata with bluish pores when fresh, generative hyphae dominating at the dissepiment edges, the presence of cystidioles, and allantoid basidiospores measuring 3.8–4.4 × 0.9–1.3 μm. Sidera parallela differs from other poroid species in the genus by having parallel tramal hyphae in combination with lunate basidiospores measuring 2.8–3.3 × 0.9–1.2 μm. Sidera srilankensis have generative and skeletal hyphae co-dominating at the dissepiment edges, and lunate basidiospores measuring 3.5–4 × 1–1.3 μm. Sidera tenuis is distinguished by small pores (8–10 per mm) and relatively long allantoid basidiospores measuring 4.2–5 × 0.8–1 μm. Sidera minutipora is characterized by buff to olivaceous buff basidiomata when dry, 5–7 pores per mm, rosette-like crystals rare, and allantoid basidiospores measuring 3.7–4.3 × 1–1.3 μm. An identification key to all accepted species is provided.

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 polypore, Daedalea americana, collected from North and Central America, is described and illustrated based on morphological characters and molecular evidence. It is characterized by annual and pileate basidiocarps, grayish brown with brown to cinnamon brown band and concentrically zonate pileal surface when fresh, cream to clay-pink pore surface, circular to angular pores (4–5 per mm) and ellipsoid basidiospores measured as 4.0–5.1 × 2.1–3.0 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions support D. americana as a distinctive species belonging to Daedalea.
