My old friend Dr. Chips lives in a place with only two seasons, cold wet and cool wet, so he sees a lot of different things than we do here in the upper midwest. Time to share an image that he sent along. Shaggy mane or inky cap are common names of this Coprinus mushroom. It's pure white inside when fresh, and edible, but it doesn't stay that way long. These are dissolving from the bottom up, a process called autodeliquescence, turning into a black spore-laden liquid. These mushrooms tend to pop up in groups after a rain. Thanks Dr. C.
