Most of which are either harmless or edible, though C. rivulosa is
deadly. Personally though, I can't see how anyone who knows M. oreades
could possibly confuse the two, despite many good handbooks warning of
the possibility. (I've been eating M.oreades since 1950 or thereabouts,
and I think I'm still alive.)

Well, that's the key, isn't it?

it is a fairy ring mushroom, and who probably couldn't tell their
Boletus from their Agaricus ;-)
