Pheromone receptor Consistent with a role of mating type in mediating cytoplasmic-nuclear genomic conflict, Agaricomycetes have evolved away from a haploid yeast phase towards hyphal fusions that display reciprocal nuclear migration after mating rather than cytoplasmic fusion. 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. -
Appendix K. Survey and Manage Species Persistence Evaluation
Appendix K. Survey and Manage Species Persistence Evaluation Establishment of the 95-foot wide construction corridor and TEWAs would likely remove individuals of H. caeruleus and modify microclimate conditions around individuals that are not removed. The removal of forests and host trees and disturbance to soil could negatively affect H. caeruleus in adjacent areas by removing its habitat, disturbing the roots of host trees, and affecting its mycorrhizal association with the trees, potentially affecting site persistence. Restored portions of the corridor and TEWAs would be dominated by early seral vegetation for approximately 30 years, which would result in long-term changes to habitat conditions. A 30-foot wide portion of the corridor would be maintained in low-growing vegetation for pipeline maintenance and would not provide habitat for the species during the life of the project. Hygrophorus caeruleus is not likely to persist at one of the sites in the project area because of the extent of impacts and the proximity of the recorded observation to the corridor. Hygrophorus caeruleus is likely to persist at the remaining three sites in the project area (MP 168.8 and MP 172.4 (north), and MP 172.5-172.7) because the majority of observations within the sites are more than 90 feet from the corridor, where direct effects are not anticipated and indirect effects are unlikely. The site at MP 168.8 is in a forested area on an east-facing slope, and a paved road occurs through the southeast part of the site. Four out of five observations are more than 90 feet southwest of the corridor and are not likely to be directly or indirectly affected by the PCGP Project based on the distance from the corridor, extent of forests surrounding the observations, and proximity to an existing open corridor (the road), indicating the species is likely resilient to edge- related effects at the site. -
BAP Fungi Handbook English Nature Research Reports
Report Number 600 BAP fungi handbook English Nature Research Reports working today for nature tomorrow English Nature Research Reports Number 600 BAP fungi handbook Dr A. 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. -

Aspects of the morp hology and ontogeny of spores and sari, which were previously disputed, have been clarified. Monokaryotic hyphae grow more densely in the intercellular spaces of Tussilago leaves than the dikaryotic intercellular hyphae on Poa. Although ultrastructurally sbnilar, monokaryotic hyphae differ from dikaryotic hyphae in their interaction with host cell walls, often growing embedded in wall material which may project into the host cells. The frequency of penetration of Poa mesophyll cells by haustoria of the dikaryon is greater than that of Tussilago cells by the relatively undifferentiated intracellular hyphae of the monokaryon. Intracellular hyphae differ from haustoria in their irregular growth, septation, lack of a neck-band or markedly constricted neck, the deposition of host wall-like material in the external matrix bounded by the invaginated host plasmalemma and in the association of callose reactions \vith intracellular hyphae and adjacent parts of host walls. -

Abstract: The polypore Bridgeoporus nobilissimus produces large perennial basidiocarps on large diameter Abies stumps, snags and trees in coniferous forests of the Pacific Northwest. Despite the size and persistence of the basidiocarps, they are rarely observed, making the conservation of this species a concern. We determined that a genetic marker for this fungus could be detected in DNA extracted from wood cores taken from trees hosting basidiocarps. We then tested 105 trees and stumps that did not host B. nobilissimus basidiocarps in plots surrounding B. nobilissimus conks, and 291 trees and stumps in randomly located plots in four stands that contained at least one B. nobilissimus basidiocarp. We found that trees of all sizes throughout all of the stands hosted B. -

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. -

Foster, [email protected] Abstract: Fungi are often inconspicuous in nature and this means it is all too easy to overlook their importance. Often referred to as the “Forgotten Kingdom”, fungi are key components of life on this planet. The phylum Basidiomycota, considered to contain the most complex and evolutionarily advanced members of this Kingdom, includes some of the most iconic fungal species such as the gilled mushrooms, puffballs and bracket fungi. Basidiomycetes inhabit a wide range of ecological niches, carrying out vital ecosystem roles, particularly in carbon cycling and as symbiotic partners with a range of other organisms. Specifically in the context of human use, the basidiomycetes are a highly valuable food source and are increasingly medicinally important. In this review, seven main categories, or ‘roles’, for basidiomycetes have been suggested by the authors: as model species, edible species, toxic species, medicinal basidiomycetes, symbionts, decomposers and pathogens, and two species have been chosen as representatives of each category. -
