A new wood-inhabiting fungal species from Yunnan Province, China, is proposed based on morphological and molecular characters. Armillaria xiaocaobaensis is characterized by a central stipe, striate to furrowed orange yellow to pinkish brown pileus surface, membranous annulus, and ellipsoid, a monomitic hyphal system with generative hyphae bearing simple septa, and slightly thick-walled basidiospores averaging 7.7 × 4.9 μm. TEF1 sequence analyses support A. xiaocaobaensis as a distinct taxon in Armillaria.

Two wood-inhabiting fungal species, Trechispora daweishanensis and T. xantha spp. nov. are proposed based on morphological features and molecular evidence. Trechispora daweishanensis is characterized by basidiomata with an annual growth habit, a tuberculate hymenophore, a monomitic hyphal system with clamped generative hyphae and ellipsoid, hyaline, thin-walled, smooth basidiospores measuring 3.8–5 × 2.7–3.5 µm. Trechispora xantha is characterized by resupinate, cracked basidiomata with a buff-coloured hymenial surface, a monomitic hyphal system and ellipsoid, hyaline, thin-walled, smooth basidiospores measuring 4.3–5.7 × 3.2–4 µm. Sequences of ITS and nLSU gene regions of the studied samples were generated. The phylogenetic analysis based on molecular data of ITS+nLSU sequences supported the novelty of these two species. Furthermore, we provide a key to the known species of Trechispora in China.

Twenty-one strains of Arthrinium were cultured from leaf samples of ten medicinal plant hosts in Yunnan Province, China. Morphological and multi-locus ITS+TUB+TEF1 sequence analyses revealed that the strains represented two previously described species (A. paraphaeospermum and A. rasikravindrae) and two new species: Arthrinium cordylines, which produces subglobose conidia that are shorter and wider than A. aureum but larger than A. hydei, and Arthrinium pseudomarii, which produces subglobose to ellipsoid conidia narrower than A. hispanicum, A. marii, and A. mediterranei.

Molecular Characters

A new poroid wood-inhabiting fungal species, Atraporiella yunnanensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by cream pore surface when dry, which is easy to separate from substrate and very rapidly stained dark brown to black when bruised; hyphal system monomitic with generative hyphae hyaline to pale brown, thin-walled, unbranched, interwoven; slightly allantoid basidiospores, 2.2–3 × 0.8–1.5 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that Atraporiella yunnanensis belonged to the residual polyporoid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to A. neotropica, and then grouped with other related genera: Antrodiella, Pouzaroporia, Steccherinum and Xanthoporus. Both morphological and molecular characters confirmed the placement of the new species in Atraporiella.

A new hypogeous species, Choiromyces cerebriformis sp. nov. is described and illustrated from Yunnan province, China. Both morphological evidence and sequence analyses of the internal transcribed spacer region (ITS1-5.8S-ITS2) support the species as new to science. C. cerebriformis differs from other Choiromyces species in having ascomata with larger lobes and light orange-brown gleba, and globose ascospores with short stick-like sparse spines ornamentation. Morphological differences and genetic distances with the similar species C. helanshanensis and C. alveolatus are discussed. A phenotypic key including related species is provided.

Vanderbylia cinnamomea is proposed as a new wood-inhabiting polypore species based on morphological characters supported by phylogenetic analysis. The species is characterized by an annual, pileate basidiocarp, a brown to black pileal surface, an olivaceous buff to smoke grey pore surface, a dimitic hyphal system with clamped generative hyphae, and subglobose to amygdaliform, hyaline, thick-walled, smooth, dextrinoid, and cyanophilous basidiospores. ITS+nLSU sequence analyses place V. cinnamomea in Vanderbylia within a subclade with a high support (100% BS, 100% BP, 1.00 BPP) sister to a subclade comprising V. fraxinea and V. robiniophila.

Decaying Wood

Asexual morph members of Tetraplosphaeriaceae (Pleosporales, Dothideomycetes) are generally hyphomycetes and usually found as saprobes occurring on various hosts in lentic habitats. Two isolates of a novel species, Tetraploa aquatica sp. nov., was collected from submerged decaying wood in Dulong river and a stream of Gaoligongshan mountain in Yunnan Province, China. The new species is characterized by short-cylindrical conidia, composed of 4-euseptate, short-cylindrical vertical columns which are verrucose at the base and with 4-setose vertical septate appendages. Tetraploa aquatica can be easily distinguished from other Tetraploa species by their columns which are 2–3-septate, aguttulate, vertical, setose appendaged which tend to remain parallel to one another apically. Phylogenetic analyses of combined LSU, ITS and SSU sequence data support its natural placement in Tetraploa. Detailed description and illustrations of this species and comparisons with other morphologically similar taxa in Tetraploa are provided.

A new poroid wood-inhabiting fungal species, Perenniporia bostonensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by resupinate, cream to buff pore surface; a dimitic hyphal system with skeletal hyphae strongly dextrinoid, unbranched, interwoven and a distinct wide lumen; ovoid to broad ellipsoid, non-truncate, hyaline, distinct thick-walled, smooth, dextrinoid basidiospores, 3.5–4.5 × 3–4 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that P. bostonensis recognized in Perenniporia sensu stricto. The new species formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to P. bannaensis and P. koreana. Both morphological and molecular characters confirmed the placement of the new species in Perenniporia.

A new, white-rot, poroid, wood-inhabiting fungal genus, Rhomboidia, typified by R. wuliangshanensis, is proposed based on morphological and molecular evidence. Collected from subtropical Yunnan Province in southwest China, Rhomboidia is characterized by annual, stipitate basidiomes with rhomboid pileus, a monomitic hyphal system with thick-walled generative hyphae bearing clamp connections, and broadly ellipsoid basidiospores with thin, hyaline, smooth walls. Phylogenetic analyses of ITS and LSU nuclear RNA gene regions showed that Rhomboidia is in Steccherinaceae and formed as distinct, monophyletic lineage within a subclade that includes Nigroporus, Trullella, and Flabellophora .

Lindtneria asiae-orientalis sp. nov. is described and illustrated from Heilongjiang Province, northeastern China. This fungus is characterized by buff-yellow to orange-yellow poroid hymenophores, septate generative hyphae with or without clamps, and relatively small ellipsoid to broadly ellipsoid basidiospores (5.8–7 × 4.7–5.2 µm). Phylogenetic analyses based on three rDNA gene regions (ITS, nLSU and tef1-α) support Lindtneria asiae-orientalis as a distinct species within the family Stephanosporaceae.

Collection of three sexual morphic fungal species occurring on the leaf surface of three plant species (Dalbergia obtusifolia, Syzygium fluviatile and Ziziphus mauritiana) collected in Yunnan Province, China, have shown that they are morphologically distinct. Phylogenetic analyses of partial sequences of internal transcribed spacer region (ITS) and large subunit rDNA (LSU) placed the three species in Trichomerium (Trichomeriaceae) but are sufficiently different from all known species. Therefore, three new species, Trichomerium multisetosum, T. xishuangbannaense and T. yunnanense are described with detailed, illustrated descriptions and notes.
