Title: Phaeocollybia of Pacific Northwest North America
Description: As a result of the 1994 presidentially mandated Record of Decision, the United States Bureau of Land Management (BLM) and Forest Service planning documents specified guidelines for surveying for 'rare' and 'uncommon' fungal species in United States forests within the range of the northern spotted owl. This document listed all but one of the described Phaeocollybia species then known to occur in the Pacific Northwest, believed to be the most highly diverse region for the genus in the world. Later taxonomic revision of the genus by the senior author -- combined with data obtained from BLM-Pacific Northwest Mycology Service cooperative research and examination of hundreds of specimens collected by Northwest Forest Plan forest surveyors -- led to the naming of ten new Phaeocollybia species. This publication offers a key to all described 25 Phaeocollybia species from the Pacific Northwest United States (California, Idaho, Washington, Oregon) and Canada (British Columbia). Detailed summary descriptions are accompanied by color photos depiciting each species in the field, in the lab, and under the microscope. Discussions of global distribution, ecology, development, biology, taxonomy, and suspected phylogenetic relationships offer essential background information to those working within and outside the Pacific Northwest region. A glossary and complete bibliography to the phaeocollybia literature are also provided.
