Calicioid lichens and fungi in the forests and woodlands of western Oregon

This study examines the diversity and ecology of calicioid lichens and fungi in western North America, with emphasis on the humid forests and woodlands of western Oregon. The study is based on 2103 species observations from 96 survey sites. This material demonstrates that calicioid lichens and fungi are a diverse component in the mycoflora of western North America. The distribution and frequency status of 82 species are documented. Most species have wide circumpolar or antitropical distributions, but there are also a number of endemics, mainly on conifer resin and bark.
