Since the publication of a preliminary list of the mosses and lichens of Emmet County in 1919, no special effort was made to add to the list of lichens, but a few additional species were picked up incidentally while collecting other plants and those are recorded here. Most of these additions were found in 1927-28. The original list contained 49 species and varieties to which have since been added 18, making a total of 67.
