Leproplaca chrysodeta is a species of saxicolous (rock-dwelling) dust lichen in the family Teloschistaceae.

[3] Leproplaca chrysodeta is characterised by a crust-like covering of powdery spherical granules, each approximately 100 μm in diameter.

When mature, these granules coalesce to form a dense, patchy crust that can appear in shades from dull orange-brown to grey-yellow.

[6] This lichen typically inhabits limestone cliffs and similar dry, shaded environments with calcareous stones.

Leproplaca chrysodeta is widely distributed across the British Isles, throughout many regions in Europe, as well as in the Middle East and New Zealand, where it is a common species.
