Ep. 226 : Lichens with Troy McMullin

Lichens been a draw for me for the last few years. When it comes to a diversity of lifeforms coming together in a fungal structure to draw down nutrients from the atmosphere, to beautify a landscape, to feed some of the largest land mammals down to sheltering some of the smallest arthropods, I’m hooked.

For many of us, the problem has been where to start, how to get into the lichens, how to identify them and how and where do we learn what roles and functions these forms of life have on the land?

In comes Dr. Troy McMullin, lichenologist with the Canadian Museum of Nature, author of dozens of papers on lichens, describer of 10 species new to science, and author of the new book Lichens : The Macrolichens of Ontario and the Great Lakes Region of the United States out on Firefly Books.

A hefty book full of colour photos, illustrated glossary, detailed keys to the 113 genera found in Ontario and some adjacent states, this book is helpful for beginner lichen lovers and for the professional lichenologist. Not only that, Troy came on to talk about his career learning about these unstudied organisms, why they are so important to him and how they can help us understand the changes we are seeing in the climate.

It’s not everyday you get to talk with one of the foremost researchers in a field. I am so grateful for the chance. I got to ask a bunch of questions which I have been wondering for a long time.. some of which are answered fully in the book, some of which it took a conversation with the author. Thanks again, Troy!
