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...
Decomposing logs in Douglas-fir - western hemlock forests in the Pacific Northwest are systems in which many organisms interact. Fungi in these systems include both mycorrhizal fungi associated with hemlock seedlings and many species of saprotrophic wood decomposer fungi. It is very likely that these two groups of fungi interact...
We investigated the root endophytic fungi of lupine using
four approaches: (1) occurrence of fungal colonization in field-collected
roots; (2) growth response of L. latifolius to inoculation
with two types of fungi; (3) structure of root colonizations of
Pinus and Lupinus by Phialocephala fortinii, a septate endophytic
fungus of lupine;...
Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head
(CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...
