A good edible mushroom – only young, closed, completely white fruit bodies; within a few hours they digest themselves (autolysis) into a black goo. Research has shown that – contrary to older field guides – it does not react with alcohol; but do not confuse it with the common inkcap, which is poisonous together with alcohol.
