The fruiting bodies may be directly attached or on a stalk.
Spores are in a fruiting body that is enclosed by a wall.
The capillitium (sterile fibres in a fruit body) is tubular.
Fruit bodies can be white, red, yellow or mauve.
Sometimes the tubes are short so the fruit bodies are almost spherical.

The white fruiting bodies are 1 to 3 mm high and around 1 mm wide.
The tip is rounded.
