The only wild mushroom that I feel 100% confident in foraging and eating is the shaggy mane (Coprinus comatus) When I was growing up my dad would often take me with him when he went "mushroom hunting" in the fall. The "Shaggies" were easy to spot and unmistakable in their identification.
They usually grow in groups of several, often all different in size, but having the same oval shape, white colour and "shaggy" appearance. Sometimes we would find them too late and turning black and inedible.
At our present home, we are lucky to have a patch of shaggies that appear each fall in the front yard. This year was no exception.
These mushrooms have a very short shelf life and are best eaten soon after harvest. These were cleaned and slightly fried to be enjoyed with breakfast. The flavour is very fine and nothing like the mushrooms you find in the grocery store.
I would really like to expand my knowledge of foraging edible mushrooms. Thanks for upvoting! 😀
