 ©Per Fadnes

Clavaria atrofusca  has black to blue-black fruitbodies which are variable in form and can sometimes be mixed with earthtongues. The fruitbody is narrowly cylindrical and 2-4 cm long.

The spores are verruculose-echinulate and approx. 6 -8.5 x3.5-5 µm. It can be confused with C. asperulospora but this has smaller spores.

Ecology

It grows in grasslands but have only a few finds in Norway, so the knowledge is inadequate. It is most probably very seldom but can have been overlooked because it is difficult to spot.

In 2019 it was found on Nautøya, Stord, which is the only find in Western Norway.
