Exidia glandulosa is a species of fungus in the family Auriculariaceae. In the UK, it has the recommended English name of witch's butter.[1] In North America it has variously been called black witches' butter, black jelly roll,[2] or warty jelly fungus.[3] It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The gelatinous basidiocarps (fruit bodies) are up to 3 cm (1.2 in) wide, shiny, black and blister-like, and grow singly or in clusters. Its occurrence elsewhere is uncertain because of confusion with the related species, Exidia nigricans.
