About Exidia pithya (Alb. & Schwein.) Fr.
Exidia pithya produces grey-black to brown-black, gelatinous fruit bodies. Fruit bodies start out button-shaped, and coalesce as they age to form spread-out patches that can grow up to 20 cm long. The upper spore-bearing surface is usually smooth, but develops slight furrowing as it matures, and occasionally has a small number of scattered pegs or warts. The spore print of this species is white. This is a wood-rotting species that typically grows on dead branches. It was first formally described from specimens collected on pine (Pinus species), but it is most commonly found growing on spruce (Picea species), and occurs less commonly on fir and larch (Abies and Larix species). It has a wide distribution across continental Europe, ranging from Scandinavia to Turkey, and is not found in the British Isles.
