Looking for Lichen ... in all the right places

By Karen Runtz, Ottawa Community News, August 21, 2017

Lichen are found on every continent and in places where most of us would never expect it — like Canada’s Arctic, home to an estimated 1,000 species and where local lichenologist Dr. Troy McMullin spent three weeks this summer collecting specimens.

Perhaps you read the Ottawa Citizen story about the interesting encounter he and fellow biologist Paul Sokoloff had there with an Arctic wolf. No? You can ask him about that when he talks to the Macnamara Club about lichen on Sept. 5.

Every lichen lives on top of something else — usually rock and soil, bark and wood, elements that are left for a long time without moving. Most are tiny and best viewed through a hand lens.
