[1][2] The genus was circumscribed by the American mycologist Ron Petersen in 1967, with Multiclavula corynoides assigned as the type species.

[3] The genus Multiclavula includes basidiolichen fungi known for their small, clavarioid (club-shaped) fruiting bodies, typically reaching up to 3 cm in height and 2 mm in thickness.

These structures are generally either unbranched or have sparse branches and come in colours ranging from white to various shades of straw, ochre, or orange.

[3] Internally, the fungi consist of contextual hyphae, which are fungal filaments running parallel and densely packed towards the base, becoming looser towards the top.

The spores of Multiclavula fungi are varied in shape, from ovoid to elongated, and have thin walls.
