Pink and Yellow Oyster Mushrooms

We picked these up from a fellow at the north end of the Sunday Square One Farmer's Market (he might only come on Sundays). He grows them organically in a place five minutes from Shelburne, Ontario, east of Toronto. He also had blue and regular oyster mushrooms, these looked the most interesting. They tasted good later, in a vegetable-mushroom-spaghetti sauce.
