Cap bell-shaped, conical, or either of those with an umbo; margin never incurved; usually some shade of grey or brown, but purplish in one unusually large species. Stem thin; either very fragile or very tough
Some species have a colored juice that can be squeezed out of the end of the stem
Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page. If there's just a few words or a microscopic feature here, a more thorough description can be found above.
