The small- to large-group-forming fruiting bodies are shiny olive to yellow-olive or brown, and bear mainly stalked, rarely sessile sporangia.

The cylindrical stem is wrinkled, dark brown at the base and becoming gradually lighter toward the top, and is filled with up to 1 mm-long, spore-like bodies.

The solid or membranous peridium is yellow, often transparent on thin areas, thickened and deeper beneath, surviving as an initially shallow calyculus.

The spores are 10 to 13 μm in diameter, and have a largely reticulated surface, the remainder being densely warty or prickly.

The slime mould is associated with, among others, species of the genera Trichia, Arcyria and Cribraria as well as Lycogala epidendrum and Stemonitis typhina.
