[1] The genus is distinguished from the other genera of Lepidostromataceae (Ertzia and Lepidostroma) by having an entirely crustose thallus and from Multiclavula (Cantharellales) by having a chlorococcoid (instead of coccomyxoid) photobiont.

The genus Sulzbacheromyces is characterised by its simple, crustose thallus which lacks any internal differentiation, having neither cortex nor medullary tissue.

[2] The reproductive structures (basidiomata) are clavarioid to caloceroid (club-shaped), unbranched, and typically coloured yellow to orange.

[3] The internal structure of the basidiomata consists of parallel, thin-walled, occasionally clamped hyphae that form a densely agglutinated central strand and a loosely organized 'medullary' tissue.

[4] The genus forms a symbiotic relationship with green algae (chlorococcoid photobionts).
