Asymbiotic N fixation in leaf litter in the Northwest was assayed by acetylene reduction. Annual N input measured by periodic sampling in a young Willamette Valley Douglas-fir plantation at Adair, Oregon was 1.08 +_.13 kg/ha. Using different calculating methods, six other annual
estimates at the Adair site ranged from 0...

Fomes annosus, Poria spp., Fomes pinicola, Coprinus spp., and Cantharellus cibarius.
Fungal organisms isolated from partially decomposed needles were phycomycetes and Fungi Imperfecti, and organisms isolated from
