The fruit bodies of Favolus species are fleshy with radially arranged pores on the underside of the cap that are angular and deeply pitted, somewhat resembling a honeycomb.

Seven years later, Fries used the name Favolus for a different genus, with the tropical species F. brasiliensis as the type.

[8][9][10] The fruit bodies of Favolus fungi are annual, and have a stipe that is situated laterally to substipitate or almost sessile.

The texture of the cap surface can be smooth, or may have minute hairs, sometimes with stiff tufts or spiny scales toward the base.

The cap cuticle is not differentiated into distinct layers; if present it comprises non-agglutinated parallel hyphae that are up to 50 μm thick.
