Common locally, it is also edible before it reaches this state. When I used to go birding with Waldo Abbott (director of the Museum of NaturalHistory) a few decades ago he would see a few of these and stop the car suddenly, leap out of the driver’s seat and go pick them. I swore he wasn’t watching the road at all, but we never had an accident. I have never eaten these mushrooms, but he was quite fond of them.
