Extract from Wikipedia article: Exidia glandulosa (common names black witches' butter, black jelly roll, or warty jelly fungus) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The 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.

Exidia glandulosa is a species of fungus that belongs to the family Auriculariaceae. It is a gelatinous fungus that grows on deciduous trees, particularly oak and maple. In East and Central Texas, it can be found growing on branches and trunks, often in shaded and humid areas. The fungus appears as a brain-like or wavy mass, typically 2-6 cm in diameter, with a brown to black color and a gelatinous texture. It is most commonly seen during the winter months, from December to February, when the weather is cool and moist.
