Tubifera is a genus of slime moulds from the subclass Myxogastria.

The fruit-bodies are aethalia formed from numerous, usually densely packed sporangia.

The oblong sporangia are ochre, pink or red to dark brown and may be shiny or shimmering.

[1] The hypothallus is spongy, occasionally raised to a stem-like, stock, dark-coloured structure or also, on Tubifera bombarda, soft and film-like thin.

The membranous, single layered peridium outlasts the below half.
