Fresh material: first grayish, black when older, smooth, resupinate, very often confluent and then up to 20 cm long, 1-2 mm thick. Surface smooth or undulating. Hymenium nearly completely without glandules. The Basidiocarp has a gelatenous consistency.
Dryed material: thin like a film, black and shiny.
