Taxomony and mycorrhizal ecology of the desert truffles in the genus Terfezia

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...

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.,...

Factors affecting germination of endomycorrhizal spores

Creator:: Daniels, Barbara Ann
Abstract:: Four isolates of Glomus mosseae, collected from diverse geographic locations, were pot cultured on varied host plants or stored in the same soil as collected. Spores of three isolates failed to germinate on any of five agar media while the fourth germinated well on all media. Lack of germination on...

Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

Factors affecting the inoculum potential of VA and ectomycorrhizal fungi in forest soils of southwest Oregon and northern California

Creator:: Parke, Jennifer Lee

The genus Leucogaster (Basidiomycetes, Leucogastraceae)

Creator:: Fogel, Robert Dale
Abstract:: Three provisional species are described as new: Leucogaster couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida is transferred to Leucogastef, completing the transfer of all Leucophlebs species to Leucogaster. L. columellatus is transferred to Sclerogaster. L. longisterigmatus is synonymized with L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...

Patterns of ectomycorrhizal host-fungus specificity in the Pacific Northwest

Creator:: Molina, R.
Abstract:: Results from approximately 400 fungus-host pure culture inoculations indicate that specificity of ectomycorrhizal associations is a complex phenomenon and cannot be based solely on field observations of sporocarp-host associations. Of the numerous sporocarp-host specific fungi tested, most formed ectomycorrhizae with one or more unexpected, non-associated hosts. These results conclusively demonstrate...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...
