Fuligo septica Flowers of Sulphur
Early stage in development of the 'aethalium' fruitbody of Fuligo septica.
The fruitbody (aethalium) is a cake-like mass, up to 20 cm in length by 3 cm deep. It is white, yellowish, ochre or red-brown, with a smooth but brittle crust. The crust breaks away to reveal a black spore-mass. Fuligo can migrate a metre or more to fruit on stumps, logs or living plants. It often fruits in the rich soil of well-manured gardens.
