Key features

Cap shaped like a thimble or bell, yellow to olive brown, with a longitudinally wrinkled/veined surface (not pitted as in a morel), attached to the stem ONLY at the top: it hangs loosely like a little cap. Stem white to cream, slender, filled with cottony tissue; sometimes poorly tolerated (ataxia, coordination disorders).
