Witches' butter

Shiny black when wet, turning olive brown and shrivelling to a warty crust during very dry weather. Individual fruitbodies are gelatinous and blend into one another like the folds of a brain. Composite blobs are typically 5 to 15 cm across. Dried and shrivelled fruitbodies are revived in wet weather and regain their expanded shape and gelatinous texture.
