I. afromontanum I. byssaceum I. epigaeum I. nipponicum I. sorediatum I. subabietinum Inoderma is a genus of lichen-forming fungi in the family Arthoniaceae.

[3] Inoderma is a genus of lichens that typically forms broad, pale, whitish to light olive-grey patches on its substrate.

Beneath this, the hypothecium is made of tangled fungal filaments within a jelly-like matrix, ranging in colour from pale to dark brown.

The asci, which are the spore-containing "sacs", follow the Arthonia-type structure and do not show a blue staining reaction with iodine solutions.

The spores are typically elongated, sometimes slightly egg-shaped (cylindric-obovoid or soleiform), and divided into two to four compartments by internal walls (septa).
