  • 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...

  • Nursery, cold storage, and field studies on western conifers inoculated with spores of Pisolithus tinctorius

    Creator:
    Alvarez, Isabel Fernandez
    Abstract:
    Inoculations of white fir, Shasta red fir, Douglas fir and ponderosa pine with Pisolithus tinctorius spores when outplanted failed to produce P. tinctorius mycorrhizae at the end of the first growing season. In the third year a few P. tinctorius mycorrhizae were formed on white fir. Inoculations reduced seedling survival...

  • 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...
