C. 2012: Wood-inhabiting fungi in southern China. 6. Polypores from Guangxi Autonomous Region. — Ann. Bot. Fennici 49: 341–351. Altogether 137 species of polypores were identified, based on specimens collected from the Guangxi Autonomous Region, southern China. A checklist of the polypores with collection data is supplied. Three new species, Junghuhnia flabellata H.S. Yuan & Y.C. Dai, Rigidoporus fibulatus H.S. Yuan & Y.C. Dai and Trechispora suberosa H.S. Yuan & Y.C. Dai, are described and illustrated. Junghuhnia flabellata is char- acterized by its flabelliform basidiocarps, small pores and small basidiospores, and skeletoystidia mostly present in dissepiments. Rigidoporus fibulatus is characterized by ceraceous to cartilaginous basidiocarps, clamp connections on generative hyphae and broadly ellipsoid to subglobose basidiospores. Trechispora suberosa is a poroid species with corky basidiocarps, ovoid to subglobose basidiospores with a finely echinulate ornamentation, and the absence of crystals on hyphae.

  • Phylogenetic Classification of Trametes
    TAXON 60 (6) • December 2011: 1567–1583 Justo & Hibbett • Phylogenetic classification of Trametes SYSTEMATICS AND PHYLOGENY Phylogenetic classification of Trametes (Basidiomycota, Polyporales) based on a five-marker dataset Alfredo Justo & David S. Hibbett Clark University, Biology Department, 950 Main St., Worcester, Massachusetts 01610, U.S.A. Author for correspondence: Alfredo Justo, [email protected] Abstract: The phylogeny of Trametes and related genera was studied using molecular data from ribosomal markers (nLSU, ITS) and protein-coding genes (RPB1, RPB2, TEF1-alpha) and consequences for the taxonomy and nomenclature of this group were considered. Separate datasets with rDNA data only, single datasets for each of the protein-coding genes, and a combined five-marker dataset were analyzed. Molecular analyses recover a strongly supported trametoid clade that includes most of Trametes species (including the type T. suaveolens, the T. versicolor group, and mainly tropical species such as T. maxima and T. cubensis) together with species of Lenzites and Pycnoporus and Coriolopsis polyzona. Our data confirm the positions of Trametes cervina (= Trametopsis cervina) in the phlebioid clade and of Trametes trogii (= Coriolopsis trogii) outside the trametoid clade, closely related to Coriolopsis gallica. The genus Coriolopsis, as currently defined, is polyphyletic, with the type species as part of the trametoid clade and at least two additional lineages occurring in the core polyporoid clade. In view of these results the use of a single generic name (Trametes) for the trametoid clade is considered to be the best taxonomic and nomenclatural option as the morphological concept of Trametes would remain almost unchanged, few new nomenclatural combinations would be necessary, and the classification of additional species (i.e., not yet described and/or sampled for mo- lecular data) in Trametes based on morphological characters alone will still be possible.

China * Correspondence to: [email protected] Abstract—Three wood-decaying fungi, Ceriporiopsis lagerheimii, Sebipora aquosa, and Tyromyces xuchilensis, are newly recorded in China. The identifications were based on morphological and molecular evidence. The phylogenetic tree inferred from ITS+nLSU sequences of 49 species of Polyporales nests C. lagerheimii within the phlebioid clade, S. aquosa within the gelatoporia clade, and T. xuchilensis within the residual polyporoid clade. The three species are described and illustrated based on Chinese material. Key words—Basidiomycota, polypore, taxonomy, white rot fungus Introduction Wood-decaying fungi play a key role in recycling nutrients of forest ecosystems by decomposing cellulose, hemicellulose, and lignin of the plant cell walls (Floudas et al. 2015). Polyporales, a large order in Basidiomycota, includes many important genera of wood-decaying fungi. Recent molecular studies employing multi-gene datasets have helped to provide a phylogenetic overview of Polyporales, in which thirty-four valid families are now recognized (Binder et al. 2013). The diversity of wood-decaying fungi is very high in China because of the large landscape ranging from boreal to tropical zones. More than 1200 species of wood-decaying fungi have been found in China (Dai 2011, 2012), and some a Chang-lin Zhao and Shi-liang Liu contributed equally to this work and share first-author status 30 ..

  • A Re-Evaluation of Neotropical Junghuhnia S.Lat. (Polyporales, Basidiomycota) Based on Morphological and Multigene Analyses
    Persoonia 41, 2018: 130–141 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2018.41.07 A re-evaluation of Neotropical Junghuhnia s.lat. (Polyporales, Basidiomycota) based on morphological and multigene analyses M.C. Westphalen1,*, M. Rajchenberg2, M. Tomšovský3, A.M. Gugliotta1 Key words Abstract Junghuhnia is a genus of polypores traditionally characterised by a dimitic hyphal system with clamped generative hyphae and presence of encrusted skeletocystidia. However, recent molecular studies revealed that Mycodiversity Junghuhnia is polyphyletic and most of the species cluster with Steccherinum, a morphologically similar genus phylogeny separated only by a hydnoid hymenophore. In the Neotropics, very little is known about the evolutionary relation- Steccherinaceae ships of Junghuhnia s.lat. taxa and very few species have been included in molecular studies. In order to test the taxonomy proper phylogenetic placement of Neotropical species of this group, morphological and molecular analyses were carried out. Specimens were collected in Brazil and used for DNA sequence analyses of the internal transcribed spacer and the large subunit of the nuclear ribosomal RNA gene, the translation elongation factor 1-α gene, and the second largest subunit of RNA polymerase II gene. Herbarium collections, including type specimens, were studied for morphological comparison and to confirm the identity of collections. The molecular data obtained revealed that the studied species are placed in three different genera. Specimens of Junghuhnia carneola represent two distinct species that group in a lineage within the phlebioid clade, separated from Junghuhnia and Steccherinum, which belong to the residual polyporoid clade.

  • A Preliminary Checklist of Arizona Macrofungi
    A PRELIMINARY CHECKLIST OF ARIZONA MACROFUNGI Scott T. Bates School of Life Sciences Arizona State University PO Box 874601 Tempe, AZ 85287-4601 ABSTRACT A checklist of 1290 species of nonlichenized ascomycetaceous, basidiomycetaceous, and zygomycetaceous macrofungi is presented for the state of Arizona. The checklist was compiled from records of Arizona fungi in scientific publications or herbarium databases. Additional records were obtained from a physical search of herbarium specimens in the University of Arizona’s Robert L. Gilbertson Mycological Herbarium and of the author’s personal herbarium. This publication represents the first comprehensive checklist of macrofungi for Arizona. In all probability, the checklist is far from complete as new species await discovery and some of the species listed are in need of taxonomic revision. The data presented here serve as a baseline for future studies related to fungal biodiversity in Arizona and can contribute to state or national inventories of biota. INTRODUCTION Arizona is a state noted for the diversity of its biotic communities (Brown 1994). Boreal forests found at high altitudes, the ‘Sky Islands’ prevalent in the southern parts of the state, and ponderosa pine (Pinus ponderosa P.& C. Lawson) forests that are widespread in Arizona, all provide rich habitats that sustain numerous species of macrofungi. Even xeric biomes, such as desertscrub and semidesert- grasslands, support a unique mycota, which include rare species such as Itajahya galericulata A. Møller (Long & Stouffer 1943b, Fig. 2c). Although checklists for some groups of fungi present in the state have been published previously (e.g., Gilbertson & Budington 1970, Gilbertson et al. 1974, Gilbertson & Bigelow 1998, Fogel & States 2002), this checklist represents the first comprehensive listing of all macrofungi in the kingdom Eumycota (Fungi) that are known from Arizona.

Relationships between wood-inhabiting fungal species richness and habitat variables in old-growth forest stands in the Pallas-Yllästunturi National Park, northern boreal Finland. Silva Fennica 45(5): 995–1013. Indicators for biodiversity are needed for efficient prioritization of forests selected for conservation. We analyzed the relationships between 86 wood-inhabiting fungal (polypore) species richness and 35 habitat variables in 81 northern boreal old-growth forest stands in Finland. Species richness and the number of red-listed species were analyzed separately using generalized linear models. Most species were infrequent in the studied landscape and no species was encountered in all stands. The species richness increased with 1) the volume of coarse woody debris (CWD), 2) the mean DBH of CWD and 3) the basal area of living trees. The number of red-listed species increased along the same gradients, but the effect of basal area was not significant. Polypore species richness was significantly lower on western slopes than on flat topography. On average, species richness was higher on northern and eastern slopes than on western and southern slopes. The results suggest that a combination of habitat variables used as indicators may be useful in selecting forest stands to be set aside for polypore species conservation.

Fennici 41: 319–329. 250 specimens of polypores were collected in the Jiuzhaigou and Huanglong nature reserves, and the Qingcheng and Ermei Mountains in Sichuan Province of southwest- ern China in October 2002. Of the 132 poroid species identified, 92 are here reported for the first time from Sichuan, and 14 are new to China. Two new species, Mega- sporoporia rhododendri Y.C. Dai & Y.L. Wei and Oxyporus macroporus Y.C. Dai & Y.L. Wei are described and illustrated..The first-mentioned species is characterized by resupinate or rarely effused-reflexed basidiocarps with pale greyish cream pore sur- face, large and ellipsoid basidiospores, and by its living exclusively on Rhododendron. Oxyporus macroporus is distinguished from the other species in the genus by its exten- sive basidiocarps, perennial habit, large pores, and by its occurrence on coniferous hosts. A new combination, Haploporus nepalensis (T. Hattori) Y.C. Dai is proposed. A checklist of Sichuan polypores, including their substrates and collecting data, is provided, based on our own materials. The major component of the northern Sich- uan polypore flora are widely distributed circumpolar, temperate and boreal species, found at higher elevations in the two nature reserves.

Eight resupinate polypores are reported from Taiwan for the first time, viz. Antrodia xantha, Megasporoporia setulosa, Oxyporus cervinogilvus, Pachykytospora papyracea, Perenniporia medullapanis, P. tephropora, Phellinus ferreus and Wrightoporia avellanea. Descriptions and microscopic line drawings are provided for the eight species. Sexuality, cultural characters, and nuclear behaviors are described for Megasporoporia setulosa and Pachykytospora papyracea. Keywords: Cultural studies; Polypores; Taiwan.
