This is a list of lichens for which there exist voucher specimens collected in Rocky Mountain National Park. Many more species should occur in the park, but currently there are few researchers working on this fascinating topic. A special thanks to Jim Bennett, USGS; the Rocky Mountain Nature Association 2004 Lichen Field Seminar class, instructor Dr. Robert Egan and William Weber, Emeritus Professor, University of Colorado, Boulder, for their work in the park and/ or for providing this information. A special thanks also goes to Connie and Stan Heginbotham for providing so many outstanding photos to illustrate this list.
