[2] Clavaria fumosa has a fruiting body which is 2–14 centimetres (0.79–5.51 in) in height and 2–5 millimetres (0.079–0.197 in) in width.

These bodies are to a greater or lesser extent cylindrical, taper at the base and are normally unbranched, they are infrequently flattened or have grooves and are usually smooth.

The flesh is the same colour as the exterior and does not have a distinct odour or taste while the spores are white.

[3] Clavaria fumosa is a common species in Britain and Ireland and is also widely distributed mainland Europe and also from North America.

[4] Clavaria fumosa is said to be edible, but as a relatively scarce and small species then their collection for culinary uses is not thought to be worthwhile.
