One Hundred New Provincial, National, and Continental Lichen and Allied Fungi Records from Parc National de la Gaspésie, Québec, Canada

Abstract

We report 100 lichen and allied fungi species for the first time from Québec, Canada. Six of these species are new to North America: Arthonia subastroidea, Biatora mendax, Cornutispora pyramidalis, Gyalecta hypoleuca, Taeniolella pertusariicola, and Varicellaria lactea. Six additional species are new to Canada: Cecidonia xenophana, Lecidea commaculans, L. herteliana, Polycoccum sporastatiae, Scoliciosporum intrusum, and Stereocaulon leucophaeopsis. All collections are from parc national de la Gaspésie on the Gaspé Peninsula in eastern Québec. Our collections were made between 2012 and 2017, primarily during Crum and Tuckerman Workshops. We provide diagnostic descriptions of all species that are new continental or national records. Our results demonstrate the park's rich and unexplored biodiversity and conservation importance, and contribute to a better understanding of the lichen and allied fungus biota of Canada and North America.
