Exidia nigricans
Foraging: Never eat a wild mushroom on a photo or an app’s word. Many deadly species look like edible ones.

About
Exidia nigricans is a species of fungus in the family Auriculariaceae. In the UK, it has the recommended English name of warlock's butter. It produces black, gelatinous basidiocarps and is a common, wood-rotting species throughout the Northern Hemisphere, typically growing on dead attached branches of broadleaf trees. It has been much confused with Exidia glandulosa.

How to use it
Warlock's butter serves an important ecological purpose by decomposing dead wood, which helps recycle nutrients back into the soil. This process supports the growth of new plants and maintains forest health. Although not edible, its presence indicates a thriving ecosystem.

In the kitchen
Warlock's butter is not eaten by humans. Its gelatinous texture and appearance might be intriguing, but it doesn't have culinary uses. Instead, it plays a vital role in the ecosystem by breaking down dead wood.
