The specific name, Procera, from the Latin procera (tall), refers to the length of the stem. There is no poisonous species for which it can be mistaken if one bears in mind that it has a long stem with bulbous base, a brownish, spotted cap with dark apex, and a broad basin about the insertion of the stem.
