The folks on the West Coast are bored with Stropharia ambigua, but for a Midwesterner on a winter (!) mushroom vacation it's about the coolest thing going. It's huge, bright yellow, slimy, and adorned with drooping white partial veil remnants. What more could you ask for in a mushroom?
So when my California friends tell me that Stropharia ambigua is a mushroom "weed" in coastal areas, I compare it with the thoroughly non-thrilling Stropharia hardii, which is the closest look-alike back east, and I wish that Hamlet had been right, and that the whole world could be "an unweeded mushroom garden, grown to seed." Yeah, I threw a word in there.
