A new polypore, Antrodia yunnanensis, collected from southwestern China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by annual, resupinate basidiocarps with greyish blue to dark greyish blue pore surface upon drying, round to angular pores measuring 2–3 per mm, a dimitic hyphal system with clamped generative hyphae, subicular hyphae bearing fine crystals, and cylindrical, thin-walled, smooth basidiospores measuring 7–9.9 × 2.5–3.1 µm. Molecular phylogeny inferred from ITS and nLSU sequence data showed that samples of A. yunnanensis formed a distinctive lineage in Antrodia sensu lato, and it nested a sister group with A. tropica.

Botryosphaeriales is an important order of diverse fungal pathogens, saprobes, and endophytes distributed worldwide. Recent studies of Botryosphaeriales in China have discovered a broad range of species, some of which have not been formerly described. In this study, 60 saprobic isolates were obtained from decaying woody hosts in southwestern China. The isolates were compared with other species using morphological characteristics, and available DNA sequence data was used to infer phylogenetic analyses based on the internal transcribed spacer (ITS), large subunit rRNA gene (LSU), and translation elongation factor 1-α (tef) loci. Three novel species were illustrated and described as Botryobambusa guizhouensis, Sardiniella elliptica, and Sphaeropsis guizhouensis, which belong to rarely identified genera within Botryosphaeriaceae. Botryobambusa guizhouensis is the second species identified from the respective monotypic genus. The previously known species were identified as Aplosporella hesperidica, Barriopsis tectonae, Botryosphaeria dothidea, Diplodia mutila, Di. neojuniperi, Di. pseudoseriata, Di. sapinea, Di. seriata, Dothiorella sarmentorum, Do. yunnana, Lasiodiplodia pseudotheobromae, Neofusicoccum parvum, Sardiniella celtidis, Sa. guizhouensis, and Sphaeropsis citrigena. The results of this study indicate that numerous species of Botryosphaeriales are yet to be revealed in southwestern China.

Two new wood-inhabiting fungi, Mycorrhaphium subadustumsp. nov. and Trullella conifericolasp. nov., are proposed and described from Asia based on ITS, nrLSU and tef1 molecular phylogeny and morphological characteristics. Mycorrhaphium subadustum is characterized by a stipitate basidiocarp, velutinate pileal surface concentrically zoned, hydnoid hymenophore, a dimitic hyphal system in spine trama and monomitic in context, absence of gloeocystidia, presence of cystidioles and the non-amyloid, cylindrical to ellipsoid basidiospores. Trullella conifericola is characterized by a laterally stipitate basidiocarp with flabelliform to semicircular pileus, hirtellous pileal surface with appressed coarse hair and concentrically zoned and sulcate, tiny pores (10–12 per mm), a dimitic hyphal system, absence of any type of cystidia, short clavate basidia and thin-walled, smooth, cylindrical to allantoid basidiospores. Phylogenetic analyses based on a three-marker dataset were performed using maximum likelihood and Bayesian inference methods. The two new species formed isolated lineages with full support in Steccherinaceae. The distinguishing characters of the two new species as well as allied species are discussed, and a key to species of Mycorrhaphium is provided.

Two new wood-inhabiting fungal species, Steccherinum tenuissimum and S. xanthum spp. nov. are described based on a combination of morphological features and molecular evidence. Steccherinum tenuissimum is characterized by an annual growth habit, resupinate basidiomata with an odontioid hymenial surface, a dimitic hyphal system with clamped generative hyphae, strongly encrusted cystidia and basidiospores measuring 3–5 × 2–3.5 μm. Steccherinum xanthum is characterized by odontioid basidiomata and a monomitic hyphal system with generative hyphae bearing clamp connections and covering by crystals, colourless, thin-walled, smooth, IKI–, CB–and has basidiospores measuring 2.7–5.5 × 1.8–4.0 μm. Sequences of the ITS and nLSU 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 + nLSU sequences showed that two new Steccherinum species felled into the residual polyporoid clade. Further investigation was obtained for more representative taxa in Steccherinum based on ITS + nLSU sequences, which demonstrated that S. tenuissimum and S. xanthum were sister to S. robustius with high support (100% BP, 100% BS and 1.00 BPP).

Aplosporella abexaminans, a new sexual morph fungus belongs to family Aplosporellaceae, was discovered on the bark of stem of Murraya koenigii (Rutaceae) and identified by morphological characteristics and analysis of combined ITS and LSU sequence data. This is the second report of a sexual morph with molecular evidence for this genus and the second record of conidiogenesis and chlamydospores associated with the asexual state of this family. It is characterized by its larger ascostromata, locules without ostioles, thinner locule peridium, two to multi-layered, larger asci, surrounded by an additional hyaline sac like structure, larger and hyaline to light olivaceous ascospores, asexual state without conidiomata formation, conidiogenous cells light brown to brown, conidia brown without granular content, smooth and presence of chlamydospores. The sexual morph of Aplosporella abexaminans resembles Bagnisiella and the asexual morph resembles Aplosporella, thus proving the sexual-asexual connection for the second time for this family.

Auriculariales is diverse, embracing a number of corticioid, poroid, and hydnoid genera. The present study covers a new wood-inhabiting fungal species of Heteroradulum niveum sp. nov that is proposed on the basis of a combination of morphological features and molecular evidence. The species is characterized by the resupinate basidiomata, a monomitic hyphal system with generative hyphae with clamp connections; tubular cystidia; two- to four-celled basidia; and allantoid, colorless, thin-walled, smooth, IKI–, CB–, basidiospores (6.5–13.5 × 2.7–5.5 µm). Sequences of ITS and nLSU rRNA gene regions of the specimens were generated, and phylogenetic analyses were carried out with methods of maximum parsimony, maximum likelihood, and Bayesian inference. These phylogenetic analyses inferred from ITS+nLSU indicated that H. niveum is nested in Heteroradulum within Auriculariales. Further study within Heteroradulum on the basis of ITS+nLSU dataset revealed that it formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and then grouped with H. yunnanensis.

Cerarioporia cystidiata gen. et sp. nov. is proposed on the basis of a combination of a specific set of morphological characters and molecular (DNA-based) evidences. Cerarioporia is characterized by seasonal, resupinate basidiomata waxy when fresh drying resinous, a dimitic hyphal system with clamped generative hyphae and skeletal hyphae, distinctly thick-walled encrusted hymenial cystidia, and hyaline, thin-walled, smooth, fusiform basidiospores. Cerarioporia cystidiata was found growing on rotten angiosperm wood, and seems to cause a white rot in very humid tropical forest. Phylogenetic analyses based on n28S, and a combined n28S and ITS datasets show that Cerarioporia belongs to the core polyporoid clade of Polyporales.
