Taxonomic Comments

Hale, M. in How to know the lichens comments that P. rufescens is a "darker brown sun-form with smaller curled lobes" and is a variant of P. canina. J. Thomson, 1984, American Arctic Lichens I., maps this species and P. canina separately, but as varieties, noting that the apparent differences are likely to be ecological varients and not true species. Egan accepts rufescens as a full species. Dale Vitt et al. recognize both P. rufescens and P. canina in Mosses, Lichens & Ferns of NW No. Am. 1988.
