Three lichen species forming both a foliose chlorotype and a dendriscocauloid cyanotype are documented from western North America. Lobaria amplissima is reported from northern California and southeastern Alaska and is new to North America. Sticta oroborealis Goward & Tønsberg, sp. nov. is described from a small area in north coastal British Columbia. The cyanotype of Sticta wrightii, hitherto unknown, is reported from coastal southeastern Alaska. The cyanotypes of all these species occur primarily as epiphytes in old-growth forests supporting a high cyanolichen diversity. The occurrence of “Dendriscocaulon” intricatulum (Nyl.) Henssen in Pacific North America is questioned.
