False parasol

Chlorophyllum molybdites

A species of Chlorophyllum, Also known as Vomiter

Though the false parasol appears unassuming, the species is famous—or, infamous—for its toxicity. It looks unfortunately similar to Agericus campestrus, a commonly eaten mushroom, but the false parasol can be distinguished by its highly unusual green spore print. Although they are no good to eat, they can be pretty to look at. The species may grow in ring-shaped groups in meadows and on forest floors in what are sometimes called "fairy circles."

Cap Diameter:

10 - 22 cm

Odor:

Mildly mushroomy but not distinctive.
