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.

Phylogenetic analyses of the combined internal transcribed spacer (ITS) of ribosomal RNA gene and translation elongation factor 1-alpha (tef1-α) sequences show that the new species forms a distinct lineage separating it from other Porodaedalea species. P. chinensis is characterized by perennial, pileate basidiocarps, relatively small pores (2–3 per mm), a dimitic hyphal system with generative hyphae bearing simple septa which are frequent in trama and skeletal hyphae dominant in context and trama, broadly ellipsoid, hyaline, thin-to slightly thick-walled, smooth, moderately cyanophilous

Taos, hew Mexico, September 25-28, 1984. JANUARY 1985 INTRODUCTION There has long been a need for a compendium of common names for tree diseases in the Western United States and Western Canada, so the authors were asked by the Chairman of the Western International Forest Disease Work Confer- ence in 1982 to prepare such a list. This is the first attempt to compile a list of common names of western tree diseases, although some publications (see references) cite several names. Ziller's (1974) is the most comprehensive for a disease group, providing common names for all tree rusts in Western Canada. In preparing this list, comments from members of the Western International Forest Disease Work Conference were solicited. The response was very good and, as was anticipated, there was considerable disagreement on appropriate common names for some diseases. In general, views of pathologists most familiar with the disease in question were relied upon. There were some suggestions that we develop a new systematic system of common names to help do away with the confusion and ambiguity that exists in the present hodgepodge of names.

(a macrofungal genus causing serious wood rot) was considered as one of the largest genera of the family Hymenochaetaceae. This genus was described to encompass poroid Hymenochaetaceae (Hymenochaetales, Basidiomycota) with perennial basidiomata and a dimitic hyphal system (Larsen & Cobb-Poulle 1990, Wagner & Fischer 2002) but these characteristic features gradually appeared to be artificial because many intermediate forms have also been reported by many workers (Fiasson & Niemelä 1984, Corner 1991, Dai 1995, 1999, 2010, Fischer 1995, Wagner & Fischer 2001).

Uprooted trees have few remaining roots (root ball, root wad). The direction of tree fall may be inconsistent rather than with the direction of prevailing wind. Remarks: The known root and butt diseases in Alaska are caused by internal wood decay (rot) fungi that may overlap with stem decay fungi. Butt rot fungi decay the heartwood at the base of the stem. Trees can live with butt rot for years or decades. Tree mortality usually occurs due to uprooting or snapping associated with the loss of structural integrity. 2 Armillaria species Armillaria Root Rot mycelial fans 3 rhizomorphs Hosts: All tree species in Alaska.

Checklist of the Aphyllophoraceous Fungi (Agaricomycetes) of the Brazilian Amazonia
Posted date: June 2009 Summary published in MYCOTAXON 108: 319–322 Checklist of the aphyllophoraceous fungi (Agaricomycetes) of the Brazilian Amazonia ALLYNE CHRISTINA GOMES-SILVA1 & TATIANA BAPTISTA GIBERTONI1 [email protected] [email protected] Universidade Federal de Pernambuco, Departamento de Micologia Av. Nelson Chaves s/n, CEP 50760-420, Recife, PE, Brazil Abstract — A literature-based checklist of the aphyllophoraceous fungi reported from the Brazilian Amazonia was compiled. Two hundred and sixteen species, 90 genera, 22 families, and 9 orders (Agaricales, Auriculariales, Cantharellales, Corticiales, Gloeophyllales, Hymenochaetales, Polyporales, Russulales and Trechisporales) have been reported from the area. Key words — macrofungi, neotropics Introduction The aphyllophoraceous fungi are currently spread througout many orders of Agaricomycetes (Hibbett et al. 2007) and comprise species that function as major decomposers of plant organic matter (Alexopoulos et al. 1996). The Amazonian Forest (00°44'–06°24'S / 58°05'–68°01'W) covers an area of 7 × 106 km2 in nine South American countries. Around 63% of the forest is located in nine Brazilian States (Acre, Amazonas, Amapá, Pará, Rondônia, Roraima, Tocantins, west of Maranhão, and north of Mato Grosso) (Fig. 1). The Amazonian forest consists of a mosaic of different habitats, such as open ombrophilous, stational semi-decidual, mountain, “terra firme,” “várzea” and “igapó” forests, and “campinaranas” (Amazonian savannahs). Six months of dry season and six month of rainy season can be observed (Museu Paraense Emílio Goeldi 2007). Even with the high biodiversity of Amazonia and the well-documented importance of aphyllophoraceous fungi to all arboreous ecosystems, few studies have been undertaken in the Brazilian Amazonia on this group of fungi (Bononi 1981, 1992, Capelari & Maziero 1988, Gomes-Silva et al.

Forty- two species belonging to nine genera are reported from the areas surveyed. An annotated, partly illustrated, checklist and identification keys are provided. The new combinations Fomitiporia bambusarum and Fulvifomes rhytiphloeus are also proposed. Atlantic Forest / Hymenochaetales / Neotropics / Taxonomy INTRODUCTION Hymenochaetaceae was formally described by Donk in 1948. It includes taxa whose basidiomata present permanent positive xantochroic reaction – dark discoloration in alkali –, yellow to brown tubes trama, simple septate generative hyphae, mono- to dimitic hyphal system, and variable occurrence of setoid structures such as hymenial or extra-hymenial setae or setal hyphae. The family encompasses a group of wood-decomposing causing white rot of wood (Hoff et al. 2004). The poroid basidiomycetes have been continuously surveyed in Southern Brazil, mainly in the last two decades (e.g.
