Hymenochaetoid fungi (Basidiomycota) of North America

摘要

28 species of the genera Asterodon, Dichochaete and Hymenochaete found in northern America (Greenland, Canada, Temperate Mexico and USA), two dubious species and one not yet found here are described, their distribution and hosts (substrata) characterized. Morphological characters in use for identification are described and keys to species found in this region are given. The number of species inhabiting different zones diminishes from southeastern USA (23 species) to nor-them Subarctic America (4 species). [References: 69]
