Interesting. I know little about fungi but I thought that most of them are extant for a very limited time (2 weeks at the most). In the San Fernando Valley of Los Angeles were I was born, I would see only two varieties: a slimy brownish colored mold specimen that grew on decayed trees and a white mushroom with a white cap with brown streaks on it; the latter seemed to go away as soon as it appeared.
