Encountered this beautiful stand of fresh shaggy ink cap mushrooms today:

I don’t believe I’ve every eaten these, though they are reported to be very tasty, but you need to act fast.  They liquify into a black ink within hours of picking them. Their spores are  distribute in the ink.  I like the story that some collectors carry a pan with them so they can eat them immediately.

Note: there is another common ink cap that’s poisonous.
