New and Interesting Macrolichens of British Columbia

Seventeen species of macrolichens are reported for the first time from British Columbia, including one new species Pannaria leucostictoides. An eastern North American species, Hypogymnia krogii, is segregated from H. enteromorpha and described as new. A new combination, Hypogymnia inactiva, is made and a preliminary key to the Hypogymnias of North America is presented. Additional information on distribution, morphology, and chemical substances is given for 37 species of lichens. The studies reported here have resulted in part from field work in British Columbia undertaken as part of a monographic study of the lichen genus Sphaerophorus. In the summer of 1969, collections were made on Vancouver Island, in the Garibaldi Provincial Park area, and along the Sunshine Coast (Gibsons Landing to Powell River). During the summer of 1970, collections were made along two transects, the first from Namu in the Burke Channel to Anahim Lake (520N), and the second from Hartley Bay in the Douglas Channel to Hazelton (540N). During the two summers in British Columbia nearly 3000 collections were made in 69 localities (Fig. 1). It is the purpose of this paper to present, as a result of these studies, the species of lichens not previously reported from British Columbia and to provide additional information for a number of rare or interesting lichens.
