Lichens on Populus tremuloides in Western Central Alberta Canada
Seventy-four lichens were found on Populus tremuloides Michx. in western central Alberta. Nine of these, Alectoria fuscescens Gyeln., A. lanestris (Ach.) Gyelyn., Bacidia chlorococca (Graewe ex Stizenb.) Lett., Collema sub- flaccidum Degel., Lecania dimera (Nyl.) Th.Fr., Nephroma helveticum Ach., Pa...

Summary: | Seventy-four lichens were found on Populus tremuloides Michx. in western central Alberta. Nine of these, Alectoria fuscescens Gyeln., A. lanestris (Ach.) Gyelyn., Bacidia chlorococca (Graewe ex Stizenb.) Lett., Collema sub- flaccidum Degel., Lecania dimera (Nyl.) Th.Fr., Nephroma helveticum Ach., Parmelia trabeculata Ahti, Physcia setosa (Ach.) Nyl. fo. virella (B. de Lesd.) and an apparently undescribed species of Bacidia had not been reported for Al- berta. The geographic distribution, vertical distribution and aspect preferences of each species are described. The following North American distribution ele- ments are represented: boreal temperate montane (23%), boreal-montane (26%7), arctic-boreal alpine-montane (26%), arctic-temperate alpine-montane (9%), boreal temperate (4%), cordilleran (3%), boreal (1%), boreal-aspen parkland (1%) and eastern boreal-subtropical (1%). In comparing the aspen epiphytic lichen flora with ten other areas in western North America, the study area was found to be most similar to that of Prince Albert National Park, Saskatchewan, Canada. |
