Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management...
Most higher plants have evolved with an obligatory symbiotic relationship with my corrhizal fungi. Epigeous mycorrhiza formers have their spores dispersed by air currents, but hypogeous mycorrhizal fungi are dependent upon small mammals as primary vectors of spore dissemination. Mammalian mycophagists defecate within the coniferous forest ecosystem, spreading the viable...
1. Distribution: A general map of distribution is given in the introduction, showing the range of the genus as a whole. A second, composite map, provides collection localities for the three species studied. Other maps indicate sites of collection for each individual species, including nests of P. longicaudus and P....
