The type specimen of Fellhanera ivoriensis was collected in the Ivory Coast, specifically in the Adiopodoume region, 17 km (11 mi) west of Abidjan at the IDERT Institute within a rainforest ecosystem.

[2] The thallus of Fellhanera ivoriensis is foliicolous, presenting as a continuous, smooth to very minutely farinose surface (as if covered with a white, mealy powder).

[2] The apothecia (fruiting bodies) of Fellhanera ivoriensis are sessile with a constricted base, rounded, and measure 0.2–0.4 mm in diameter.

[2] Pycnidia in Fellhanera ivoriensis are wart- to barrel-shaped, 0.1–0.15 mm in diameter, and chamois-coloured with a wide ostiole.

Other species with similar dark apothecia, such as F. lambinonii, F. seroexspectata, and F. muhlei, differ in either their apothecial discs or thallus and soralia characteristics.
