North American winter oyster mushrooms are found between and early fall and spring. Despite the name "winter", temperatures don't need be cold for them to fruit, but it does help. They fruit well in temps of 45F-70F. Winter oysters are one of the best edible mushrooms. They can reach 9 inches across when fully mature, though 4 - 6 inches are more common. They have a super-dense, meaty texture. They make an exceptional vegan alternative to meat or seafood, especially when properly prepared. They are also great on the grill.
