Sporocarp densely covered with hairs of 2 kinds, erect and flattened appressed, which in the dried state cause the powdery greyish appearance of the sporocarp. Sporocarps set at an angle of 90° to the pedicel; pedicels 8-15 mm, erect or arching, free, arising from the axil of the stipe, with bristly hairs.
