I found a mushroom, can the MST tell me what it is?

It's very difficult to identify mushrooms only from photographs. Any identification we make from a photo will be tentative, and for reasons of liability the MST can't provide firm identifications. The MST accepts no responsibility for any illness or complication resulting from eating a mushroom based on a tentative identification provided from photographs. If your specimen was found outside Ontario, we won't be able to identify it for you. Species vary greatly between geographic locations and our members are familiar with the species that grow in our area.

If you still want your mushroom identified, please send your photos to This email address is being protected from spambots. You need JavaScript enabled to view it. or This email address is being protected from spambots. You need JavaScript enabled to view it.. Please include as much of the following information as possible:

  • Location (e.g. Guelph)
  • Date the specimen was observed
  • Habitat (e.g. in grass)
  • Species of any nearby trees
  • Spore print colour
  • Distinctive smells
  • Colour changes

Please send photos of the specimen from all angles (showing underneath the cap, the stem etc.) and of the specimen cut in half from top to bottom through the stem. Please make sure the mushroom fills the picture frame - blurry photos taken from eye-level guarantee that we won't be able to help you.

The more information you can provide, the more likely we'll be able to provide a tentative identification of your specimen.
