A combinaton of opportunistc and plot-based sampling was carried out in order to maximize the documentaton of polypore distributon. The study was conducted throughout the entre study period of 2013–2015. Fify-seven polypore species in 29 genera belonging to seven families were documented from the natonal park. The wet evergreen forest was enriched with 52 species whereas the shola forest harboured 20 polypore species. Fifeen species were found in both ecosystems while fve species were exclusively found in the shola forest. The Polyporaceae was the dominant family with 30 species, followed by Hymenochaetaceae with 16 species, and Fomitopsidaceae and Meripilaceae with three species each. Ganodermataceae and Schizoporaceae made their presence with two species each while only one species was reported under family Meruliaceae. Among the polypores documented, 42 species were annuals and 15 were perennials. While analyzing the rot characteristcs of the recorded polypores, it was found that white rot polypores have notable dominance over brown rot polypores. Out of the 57 species analysed, 52 polypores were white roters and only fve species were brown roters. During the present study, three species (Phylloporia pectnata, Trametes menziesii, and Trametes ochracea) were found to be new records from the southern Western Ghats. An identfcaton key was developed for the polypores documented from Silent Valley Natonal Park based on micro and macro morphological features.

Importantly, the evolution of this mating behavior is precisely timed with the onset of diversification of mating type alleles at the pheromone/receptor mating type loci that are known to control reciprocal nuclear migration during mating.

Martyn Ainsworth 53 Elm Road, Windsor, Berkshire. SL4 3NB October 2004 You may reproduce as many additional copies of this report as you like, provided such copies stipulate that copyright remains with English Nature, Northminster House, Peterborough PE1 1UA ISSN 0967-876X © Copyright English Nature 2004 Executive summary Fungi constitute one of the largest priority areas of biodiversity for which specialist knowledge, skills and research are most needed to secure effective conservation management. By drawing together what is known about the 27 priority BAP species selected prior to the 2005 BAP review and exploring some of the biological options open to fungi, this handbook aims to provide a compendium of ecological, taxonomic and conservation information specifically with conservationists’ needs in mind. The opening section on fungus fundamentals is an illustrated account of the relative importance of mycelia, fruit bodies and spores, without which many ecosystem nutrient cycles would cease. It is not generally appreciated that mycelia have been recorded patrolling territories of hundreds of hectares, living over a thousand years or weighing as much as a blue whale. Inconspicuous fungi are therefore amongst the largest, heaviest and oldest living things on Earth. The following sections describe the various formal and informal taxonomic and ecological groupings, emphasizing the often intimate and mutually beneficial partnerships formed between fungi and other organisms. The different foraging strategies by which fungi explore their environment are also included, together with a summary of the consequences of encounters between fungi ranging from rejection, combat, merger, takeover and restructuring to nuclear exchanges and mating.

(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.

An updated checklist of polypores for Gilan Province is provided. Altogether, 66 polypores are known from Gilan up to now. Key words: fungi, hyrcanian forests, poroid basidiomycetes.

China * Correspondence to: [email protected] Abstract—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. Key words—Polyporales, residual polyporoid clade, taxonomy, wood-rotting fungi Introduction Polyporales Gäum. is one of the most intensively studied groups of fungi with many species of interest to fungal ecologists and applied scientists (Justo & al. 2017). Species of wood-inhabiting fungi in Polyporales are important as saprobes and pathogens in forest ecosystems and in their application in biomedical engineering and biodegradation systems (Dai & al. 2009, Levin & al. 2016). With roughly 1800 described species, Polyporales comprise about 1.5% of all known species of Fungi (Kirk & al.
