It's mushroom season in the Greater Parry Sound Area. I have virtually no experience in identifying mushrooms beyond the most obvious types, notably amanita muscaria. In my online researching I came across a detailed Agriculture Canada publication called Edible and Poisonous Mushrooms of Canada. It was published in 1979 including some beautiful artwork, and runs over 300 pages in length. It is available in PDF format for free through this link. It's a rather large file, over 30 MB, but should still fit nicely on most smartphones and tablets for use as a desk and field guide.
