Völlige Verzweiflung (FOHL-ikh-ə fer-TSVY-floong; Ger. "complete despair"), also known as "the Black Despair Mushroom", is a mushroom plant which can be found mostly in the Black Forest and it is featured in the television show Grim. It is similar to a rare strain of fungus called Ophiocordyceps unilateralis from the tropics, which attacks carpenter ants, causing them to climb into trees where their insides burst, spreading the fungal spores. When eaten raw, the mushrooms are harmless, but when cooked, they release a toxin fatal to Blutbaden.
