Morphological and molecular identification of two new species of Tubulicrinis (Hymenochaetaceae,Hymenochaetales) from southern China

Two new wood-inhabiting fungal species, Tubulicrinis xantha and T. yunnanensis spp. nov., are described based on morphological and molecular characters. Tubulicrinis xantha is characterized by resupinate, furfuraceous basidiomata with buff to yellowish hymenial surface, amyloid lyocystidia and cylindrical to allantoid, hyaline, thin-walled, smooth basidiospores (5.3–6.3 × 1.2–1.6 μm). Tubulicrinis yunnanensis is characterized by pruinose basidiomata with primrose to olivaceous hymenial surface and encrusted lyocystidia and cylindrical, hyaline, thin-walled, smooth basidiospores (4.2–6.2 × 1.2–2 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 T. xantha grouped with T. martinicensis, and T. yunnanensis grouped with T. glebulosus.     

Three new species of <Emphasis Type="Italic">Hyphodontia</Emphasis> s.l. (Basidiomycota) with poroid or raduloid hymenophore

Three species of Hyphodontia (Schizoporaceae) with poroid or raduloid hymenial surface are described as new to science. Hyphodontia chinensis sp. nov. was found in southwest and northeast China, having raduloid hymenophore, ventricose to subulate cystidia, and slightly thickened-walled, ellipsoid basidiospores; H. reticulata sp. nov. was found in central Japan and northern Taiwan, having poroid hymenophore, projecting peg-like structures, and encrusted cystidia; H. subtropica sp. nov. was collected from China (Yunnan province) and northern Vietnam, having poroid hymenophore, slightly apically swollen cystidioles, and pseudodimitic hyphal system. Both maximum parsimony and Bayesian methods were used to construct the phylogenetic trees based on ITS (internal transcribed spacer) sequences. The independent status of each proposed new species is based on morphological study, further confirmed by ITS-based phylogenetic analysis. The recently presented H. dimitica is found to be conspecific with H. nongravis, based on morphological and molecular evidences.     

<Emphasis Type="Italic">Ceriporiopsis kunmingensis</Emphasis> sp. nov. (Polyporales,Basidiomycota) evidenced by morphological characters and phylogenetic analysis

A new poroid wood-inhabiting fungal species, Ceriporiopsis kunmingensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by resupinate basidiocarps with pale cinnamon-buff to ochreous color when dry; generative hyphae unbranched and subparallel along the tubes; presence of hyphal ends; allantoid basidiospores, 4.5–5 × 1.5–2 μm. The internal transcribed spacer (ITS) and 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 C. kunmingensis belonged to the phlebioid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP), and was closely related to Phlebia aurea, and then grouped with P. livida and P. subserialis. Both morphological and molecular characters confirmed the placement of the new species in Ceriporiopsis.     

Xylodon kunmingensis sp. nov. (Hymenochaetales,Basidiomycota) from southern China

A new wood-inhabiting fungal species, Xylodon kunmingensis, is proposed based on morphological and molecular evidences. The species is characterized by an annual growth habit, resupinate basidiocarps with cream to buff hymenial, odontioid surface, a monomitic hyphal system with generative hyphae bearing clamp connections and oblong-ellipsoid, hyaline, thin-walled, smooth, inamyloid and indextrinoid, acyanophilous basidiospores, 5–5.8 × 2.8–3.5 μm. The phylogenetic analyses based on molecular data of ITS sequences showed that X. kunmingensis belongs to the genus Xylodon and formed a single group with a high support (100% BS, 100% BP, 1.00 BPP) and grouped with the related species X. astrocystidiatus, X. crystalliger and X. paradoxus. Both morphological and molecular evidences confirmed the placement of the new species in Xylodon.

<Emphasis Type="Italic">Leifiporia rhizomorpha</Emphasis> gen. et sp. nov. and <Emphasis Type="Italic">L. eucalypti</Emphasis> comb. nov. in Polyporaceae (Basidiomycota)

A new poroid wood-inhabiting fungal genus, Leifiporia, is proposed, based on morphological and molecular evidence, which is typified by L. rhizomorpha sp. nov. The genus is characterized by an annual growth habit, resupinate basidiocarps with white to cream pore surface, a dimitic hyphal system with generative hyphae bearing clamp connections and branching mostly at right angles, skeletal hyphae present in the subiculum only and distinctly thinner than generative hyphae, IKI–, CB–, and ellipsoid, hyaline, thin-walled, smooth, IKI–, CB– basidiospores. 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 analysis based on molecular data of ITS + nLSU sequences showed that Leifiporia belonged to the core polyporoid clade and was closely related to Diplomitoporus overholtsii and Lopharia cinerascens, and then grouped with Pycnoporus and Trametes. Further investigation was obtained for more representative taxa in the Polyporaceae based on nLSU sequences, in which the results demonstrated that the genus Leifiporia formed a monophyletic lineage with a strong support (100 % BS, 100 % BP, 1.00 BPP). Both morphological and molecular evidence confirmed the placement of the new genus in the core polyporoid clade. In addition, a new combination, Leifiporia eucalypti, is proposed based on examination of its type material and phylogeny.     

Taxonomy and phylogeny of Ceriporia (Polyporales,Basidiomycota) with an emphasis of Chinese collections

Ceriporia accommodates a kind of wood-inhabiting polypores producing resupinate basidiocarps and causing a white rot. More than 30 species of this genus have been described; however, only a few species were referred to molecular phylogeny. In this study, a total of 203 specimens of Ceriporia were studied morphologically, and the ITS and/or nLSU regions from 42 samples, representing 18 species, were sequenced for phylogenetic analysis. Based on both morphological and phylogenetic analyses, three new species of Ceriporia, C. bubalinomarginata, C. pseudocystidiata and C. variegata, are described and illustrated. An annotated identification key is provided for all 20 species of this genus thus far known in China. Our phylogeny shows that (1) Ceriporia is not monophyletic, (2) C. spissa and C. viridans as morphologically circumscribed are polyphyletic, (3) C. inflata is retained for both C. inflata and C. jiangxiensis, and (4) presence or absence of hymenial cystidia is not a useful character in delimiting species relationships in Ceriporia.
