The stipe may be clothed at the base with a hispid mycelium of a whitish colour.

The stipe is flattened or lobed in cross section and has a pale to light yellow colour, thus it is concolorous with branches.

[2] The branches are flattened and can be covered with white powder (spores) and hispid from cystidia.

The colour is a pale to light yellow when young but can become fleshy brown to violaceous tan.

avellanea are globose, broadly ovate and hyaline (thin and translucent); 7.6–11.2 x 7.9–10.4 μm.
