Toby Spribille is a lichenologist, specialising in evolution and taxonomy. He identified the presence of yeast cells as an additional fungal component of some lichens. He works at University of Alberta and is the Canada Research Chair in Symbiosis.

Toby Spribille was born in the US and educated at home. He was interested in science but lacked conventional qualifications. Therefore, he studied at University of Göttingen in Germany. He subsequently studied for a doctorate at the University of Graz, Austria which was awarded in 2011.^[1]

He first worked in forestry. After academic study in Europe, he undertook postdoctoral research at both the University of Graz and University of Alberta between 2012 and 2017. Spiribille worked with John McCutcheon at University of Alberta to apply molecular biology methods to the lichen symbiosis. He was then able to take up a post as an associate professor in biological sciences at the University of Alberta in Canada in 2017.^[1][2]

His research focuses on lichens, especially their evolution, ecology and diversity. He uses technologies from microscopy and molecular biology.^[2] In 2016, he and colleagues identified the presence of basidiomycota yeasts within the structure of lichen species in North American through using a combination of microscopy and molecular genetic methods.^[3] This was a new, unexpected, discovery since lichens were considered to consist of one fungus and one (or two) photosynthetic algal or bacterial components. The additional fungal component has also been found in lichens around the world. This discovery has added to understanding of the lichen symbiosis, and the gradation between parasitism and mutualism.^[4][5] Spribille has also identified, or revised the nomenclature, of several species of northern American lichens.^[1]

The North American lichen Cliostomum spribillei was named in his honour in 2016.^[6]
