  • Species Diversity and Molecular Phylogeny of Cyanosporus (Polyporales, Basidiomycota)
    Frontiers in Microbiology, 2021
    Co-Authors: Shun Liu, Lu-lu Shen, Yan Wang, Genevieve Gates, Bao-kai Cui
    Abstract:

    Cyanosporus is a cosmopolitan brown-rot fungal genus, recognizable by blue-tinted basidiocarps. Species in this genus were usually treated as belonging to the Postia caesia complex, however, recent phylogenetic analyses showed that this complex represents an independent genus. During further studies on Cyanosporus, five new species were discovered based on morphological features and molecular data. Phylogenetic analyses of Cyanosporus were conducted using the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), the small subunit of nuclear ribosomal RNA gene (nSSU), the small subunit of mitochondrial rRNA gene (mtSSU), the largest subunit of RNA polymerase II (RPB1), the second largest subunit of RNA polymerase II (RPB2), and the translation elongation factor 1-α gene (TEF); illustrated descriptions of the new species are provided. In addition, fifteen species previously belonging to the Postia caesia complex are transferred to Cyanosporus and proposed as new combinations.

  • Taxonomy and phylogeny of Postia. Multi-gene phylogeny and taxonomy of the brown-rot fungi: Postia (Polyporales, Basidiomycota) and related genera
    Persoonia, 2018
    Co-Authors: Lu-lu Shen, Bao-kai Cui, M. Wang, J.-l. Zhou, Jia-hui Xing, Yu-cheng Dai
    Abstract:

    Phylogenetic and taxonomic studies on the brown-rot fungi Postia and related genera, are carried out. Phylogenies of these fungi are reconstructed with multiple loci DNA sequences including the internal transcribed spacer regions (ITS), the large subunit (nLSU) and the small subunit (nSSU) of nuclear ribosomal RNA gene, the small subunit of mitochondrial rRNA gene (mtSSU), the translation elongation factor 1-α gene (TEF1), the largest subunit of RNA polymerase II (RPB1) and the second subunit of RNA polymerase II (RPB2). Ten distinct clades of Postia s.lat. are recognized. Four new genera, AmaroPostia, CalciPostia, CystidioPostia and FuscoPostia, are established, and nine new species, AmaroPostia hainanensis, Cyanosporus fusiformis, C. microporus, C. mongolicus, C. piceicola, C. subhirsutus, C. tricolor, C. ungulatus and Postia sublowei, are identified. Illustrated descriptions of the new genera and species are presented. Identification keys to Postia and related genera, as well as keys to the species of each genus, are provided.

  • Morphological characters and molecular data reveal two new species of Postia (Basidiomycota) from China
    Mycological Progress, 2015
    Co-Authors: Lu-lu Shen, Hong-xia Liu, Bao-kai Cui
    Abstract:

    Two new species of Postia are described from China based on morphological characters and molecular data. Postia gloeopora sp. nov. is characterized by pileate and white flabelliform basidiomata, glue pores when dry, gelatinous hyphae at the dissepimental edge, abundant oily substances in context and trama, and ellipsoid basidiospores (4–4.5 × 2–2.5 μm). Postia ochraceoalba sp. nov. is characterized by imbricate basidiomata, ochraceous pileal surface with concentric zones, white pore surface, small angular pores (6–7 per mm) with dentate dissepiments, and allantoid basidiospores (4–4.5 × 1–1.5 μm). Phylogenetic analysis based on the internal transcribed spacer and nuclear large subunit ribosomal RNA gene regions confirmed the affinity of the new species in Postia and indicated their relationships with other species in the genus.

  • A new species of Postia (Polyporales, Basidiomycota) from China based on morphological and molecular evidence
    Phytotaxa, 2014
    Co-Authors: Lu-lu Shen, Bao-kai Cui, Yu-cheng Dai
    Abstract:

    A new polypore, Postia duplicata , collected in Yunnan and Zhejiang provinces, is described and illustrated on the basis of morphological and molecular characters. Postia duplicata is characterized by pileate basidiomata with pale brownish to brown pore surface when bruised, duplex context, a monomitic hyphal system with clamped generative hyphae, presence of gloeocystidia in the hymenium, and cylindrical basidiospores (3.8–5.8 × 1.8–2.5 µm). Both morphological and molecular evidence confirmed the placement of the new species in Postia and showed its phylogenetic relationships.

  • Morphological and Molecular Evidence for a New Species of Postia (Basidiomycota) from China
    Cryptogamie Mycologie, 2014
    Co-Authors: Lu-lu Shen, Bao-kai Cui
    Abstract:

    Abstract A new polypore, Postia hirsuta sp. nov., collected in Shaanxi Province, central China, is described and illustrated on the basis of morphological characters and molecular data. This fungus is characterized by an annual growth, pileate basidiocarps with a mousegrey and hirsute pileal surface, a white to straw-colored pore surface, a monomitic hyphal system with thick-walled generative hyphae, and allantoid to cylindrical basidiospores (4-4.8 × 1-1.2 µm). Phylogenetic inferences based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported Postia hirsuta as a distinct species in Postia.

  • The phylogenetic position of Postia s.l. (Polyporales, Basidiomycota) from Patagonia, Argentina
    Mycologia, 2012
    Co-Authors: María Belén Pildain, Mario Rajchenberg
    Abstract:

    We investigated the phylogenetic relationships of Postia species from Patagonia with rDNA ITS and LSU sequences, together with morphological, cultural and biological features. All species in the genus were included in a “Postia clade” irrespective of whether their spores were thin- or thick-walled. This clade is characterized by tetrapolar mating, a normal nuclear behavior, metachromatic generative hyphae and absence of fiber hyphae in culture. One subclade merged the austral taxa P. pelliculosa and P. punctata, but otherwise no distinct relationships were found regarding spore shape, spore wall thickness and geographical distribution of taxa. The austral P. venata and the endemic P. carbophila, with thin-walled basidiospores, occupied variable positions in both analyses. Postia caesia from Patagonia grouped within the P. caesia species complex but on a separate branch. In contrast, P. rennyi and P. balsamea from Patagonia corresponded well with strains from other geographic areas. The two austral species...

  • Notes on New Zealand polypores (Basidiomycetes) 2. Cultural and morphological studies of selected species
    New Zealand Journal of Botany, 1995
    Co-Authors: Mario Rajchenberg
    Abstract:

    Abstract The taxonomic positions of several New Zealand polypore fungi were examined using morphological, cultural, sexual, and nuclear criteria. Postia venata (Rajchenb. & Wright) Rajchenb., previously described from Nothofagus forests in Argentina, is newly recorded in New Zealand on Nothofagus spp. It is distinct from Postia atrostrigosa (Cooke) comb. nov., which has a pileated fruit body and wider, strictly allantoid, IKI+ basidio-spores. Postia venata is also distinct from Tyromyces setiger (Cooke) G.H. Cunn., which has a pileated, uniformly strigose, white, triquetrous fruit body, and strictly allantoid spores. Skeletocutis stramenticus (G.H. Cunn.) comb. nov. is shown to be conspecific with S. australis Rajchenb., also reported from Argentina. Polyporus hemitephrus Berk, is a white rotting wood decay species and belongs in Fomes (Fr.) Fr. Cultural descriptions are given for Fomes hemitephrus (Berk.) Cooke, P. venata, and Schizopora nothofagi (G.H. Cunn.) P.K. Buchanan & Ryv. Cultural evidence suppo...

  • Polypore diversity of Fenglin Nature Reserve, northeastern China
    2006
    Co-Authors: Yu-cheng Dai, R Penttila
    Abstract:

    Field investigations on wood-rotting fungi in Fenglin Nature Reserve, northeastern China, were made in 1999-2002, and nearly 700 specimens were collected by the authors. Based mostly on the collected material, 161 poroid wood-inhabitin or species were identified, and this paper gives a checklist of our results. Substrates and collecting data of each species are supplied in the checklist. Five species, Junghuhnia semisupiniformis (Murrill) Ryvarden, Postia ceriflua (Berk. & M.A. Curtis) Julich, Postia rancida (Bres.) M.J. Larsen & Lombard, Skeletocutis papyracea A. David, and Tyromyces canadensis Overh. ex J. Lowe, are new to China. Antrodia hingganensis Y.C. Dai & Penttila and Postia amurensis Y.C. Dai & Penttila are new to science. The species diversity of polypores in Fenglin Nature Reserve is very high in regional, stand and tree species level when compared with North European data. The number of endemic species is much higher than that known from Europe. A high number of host tree species, lack of Pleistocene glaciations and favourable geography are the likely explanations to the observed high species diversity and level of endemism.

  • A preliminary study on wood-inhabiting fungi on charred wood in Daxinganling forest areas
    Ying yong sheng tai xue bao = The journal of applied ecology, 2004
    Co-Authors: Yu-cheng Dai, Zhengquan Wang
    Abstract:

    Study on wood-inhabiting fungi is one of the active fields of mycology during past 30 years in China, and the study mostly focused on natural forest without fire disturbing. Forest fire changes forest ecology dramatically, and the fungi on charred wood are different from those in nature forests without fires. In this paper, we focused on the wood-inhabiting fungi growing on charred wood in Daxinganling forest areas. Seventeen species were reported: Antrodia sp., Antrodia rantha, Ceriporiopsis mucida, Diplomitoporus lindbladii, Gloeophyllum carbonarium, Gloeophyllum sepiarium, Gloeoporus taricola, Laurilia sulcata, Oligoporus sericeomollis, Phellinus igniarius, Postia caesia, Postia leucomallella, Postia tephroleuca, Schizopora flavipora, Skeletocutis ochroalba, Skeletocutis vulgaris, and Trichaptum fuscoviolaceum. Among them, eight species caused brown rot, and nine species caused white rot. Based on our field studies, eight species were pioneer fungi in charred wood, four species were common one, and three species were rare or threatened in the studied area. Setting up nature reserve should be the best way to protect the rare or threatened species of wood-inhabiting fungi.
