 Novices may mistake juvenile death caps for edible puffballs or mature specimens for other edible Amanita species , such as A. lanei , so some authorities recommend avoiding the collecting of Amanita species for the table altogether . The white form of A. phalloides may be mistaken for edible species of Agaricus , especially the young fruitbodies whose unexpanded caps conceal the telltale white gills ; all mature species of Agaricus have dark @-@ colored gills .
