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...

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...

Pseudaleuria quinaultiana, a new genus and species of operculate ascomycete from the Olympic Peninsula

Creator:: Lusk-Newman, Demaris E.
Abstract:: Pseudaleuria quinaultiana gen. et sp. nova is described in English and Latin. P. quinaultiana is compared with Aleuria, Anthracobia Cheilymenia, Geopyxis, Humaria, lodophanus, Jafnea, Leucoscypha, Melastiza, Octospora, Pyronema, Scutellinia, Sphaerosporella, Tricharina, Morchella, Cookeina, Phillipsia, Pseudoplectania, Sarcoscypha, and Sarcosoma. Of these genera P. quinaultiana has hairs most similar to those found...

Incompatibility reactions and nuclear condition of three Phellinus species

Creator:: Hennon, Paul E.
Abstract:: Phellinus arctostaphyli (Long) Niemela, P. igniarius (L. ex Fr.) Quel., and P. tremulae (Bond.) Bond. et Boriss., heartrotting hymenomycetes in the family Hymenochaetaceae (Aphyllophorales), all conform to a multi-allelic heterothallic mating system. Both compatible and incompatible reactions result from pairings of homokaryons from the same basidiocarp. Homokaryons isolated from different...

Apple mycorrhizae and their effects on growth and nutrient concentration in apple seedlings grown in two soils with varied levels of P

Creator:: Geddeda, Yosef Ibrahim
Abstract:: A study was conducted to characterize the vesicular-arbuscular (VA) fungi of apples grown in Oregon. Using roots and soil from apple orchards as inoculae, six different fungal species were found in pot cultures: Gigaspora margarita Becker and Hall, Glomus fasciculatum (Thaxter sensu Gerdemann) Gerd. and Trappe, Glomus mosseae (Nicol. and...

Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

The biology of the predator complex of the filbert aphid, Myzocallis coryli (Goetze), in western Oregon

Creator:: Messing, Russell H.
Abstract:: Commercial filbert orchards throughout the Willamette Valley were surveyed for natural enemies of the filbert aphid, Myzocallis coryli (Goetze). A large number of predaceous insects were found to prey upon M. coryli, particularly members of the families Coccinellidae, Miridae, Chrysopidae, Hemerobiidae, and Syrphidae. Also, a parasitic Hymenopteran (Mesidiopsis sp.) and...
