Flavoplaca arcis is a species of saxicolous (rock-dwelling), crustose to squamulose (scaley) lichen in the family Teloschistaceae.

[3] Ulf Arup and colleagues transferred the taxon to the genus Flavoplaca in 2013, following a molecular phylogenetics-based restructuring of the family Teloschistaceae.

These areoles are rather thick, ranging in diameter from 0.4 to 2 mm, and some are adorned with coarse, spherical reproductive structures known as blastidia, which match the colour of the thallus.

[5] Reproductive structures known as apothecia are zeorine in form (with a disc that is surrounded by a pale thalline margin, which has both algal and fungal cells), adnate (attached flatly) to sessile, yellow, and between 0.3 and 1.5 mm in width.

Its distribution spans Western and Central Europe, Scandinavia, the Mediterranean region, the Balkan Peninsula, and the Canary Islands.
