Mycorrhizal status of post-fire Pezizales

Creator:: Fujimura, Kei E.
Abstract:: Post-fire Pezizales often fruit seasonally approximately six weeks after a fire in successional groups over the course of two years. Two methods, pure culture synthesis and PCR-based identification, were used to determine if some of these species were mycorrhizal. Eleven fungal isolates, Anthracobia melaloma, Gyromitra infula, Helvella compressa, Morchella sp.,...

Systematics of Pacific Northwestern species of the genus Gymnomyces inferred from nuclear ribosomal DNA internal transcribed spacer sequences

Creator:: Whitbeck, Kristen L.
Abstract:: Gymnomyces is an ectomycorrhizal basidiomycete genus in the family Russulaceae estimated to contain less than 50 species worldwide, with 23 species known to occur in the Pacific Northwest. Gymnomyces species are common in Pacific Northwest forests that include Pseudotsuga, Abies, Tsuga, and Quercus. They produce sequestrate (truffle-like) sporocarps with ornamented...

Taxonomy of desert truffles : the genera Phaeangium and Tirmania

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi are important in food production of arid lands. The desert truffles not only form a symbiotic association with range plants but also form fruiting bodies which are both prized as food and nutritious. The taxonomy and ecology of two genera of desert truffles are treated in this thesis....

Distribution of Acremonium coenophialum in developing seedlings and inflorescences of Festuca arundinacea

Creator:: Cook, Kathy L.
Abstract:: Acremonium coenophialum is an endophytic fungus which infects the reproductive and vegetative tissue of tall fescue. Interest in this fungus was sparked by research which linked its presence in tall fescue with reduced weight gains and alkaloid-like poisoning in cattle. Incomplete information was available on the endophyte's life or disease...

Fungal diversity within decomposing woody conifer roots in Oregon

Creator:: Vandegrift, V. Eleanor
Abstract:: Previous studies have indicated that roots from five tree species (Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Pinus contorta) decompose at different rates across an environmental gradient in Oregon. Measurements of wood chemistry from each tree species as well as moisture and temperature from each location do not...

Systematics of the genus Otidea in the Pacific Northwest

Creator:: Peterson, Eric T.
Abstract:: The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...

An Exploration of the Ecological and Geographical Variability of Rhizopus microsporus Clinical and Environmental Isolates

Creator:: Stairs, Brandon S.
Abstract:: Rhizopus microsporus is a globally ubiquitous opportunistic human and plant pathogen that is known to harbor endosymbiotic bacteria. Differences between populations of clinical and environmental R. microsporus isolates have yet to be assessed on a global scale. Whole-genome sequence data were used to explore fungal biology and to assess potential...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....
