Poisonous toadstool

"Your Majesty, this very morning, Sabre died of eating a poisonous toadstool! Bring him back to life, Your Majesty, with your wand!"

- Captain of the Brigade of Witch-Hunters.

A poisonous toadstool is a fungus not fit for consumption. In popular wizarding tale Babbitty Rabbitty and her Cackling Stump by Beedle the Bard, Sabre, the largest of the hounds of the Brigade of Witch-Hunters, died of eating this fungus.
