The fruit body are aethalia from numerous, closely pressed together sporangia, sometimes also smaller, looser or bundled grouplets. The oblong sporangia are ochre, pink or red to dark brown and may be shiny or shimmering. They open at the tip to release the spores.
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 is outlasting the below half. A pseudocapillitium may missing or exist. The spores are light yellow to red-brown.
The genus was first described in 1873 by Józef Thomasz Rostafiński. The type species is Tubifera ferruginosa, first characterized as a Stemonitis species. The genus comprises five species, including:
- Tubifera applanata
- Tubifera ferruginosa
- Tubifera microsperma
- Tubifera casparyii
- Tubifera bombarda
