A minute grey lichen, characterized by its granular to squamulose thallus and short pseudopodetia (up to 2 mm) with black apothecia on the top. It grows on siliceous rocks and stones, which are not directly exposed to the sun and are humid, e.g., due to water seepage. The species has an oceanic distribution. In Europe, it only occurs in Great Britain and Scandinavia. The only Czech and central European locality is in the Labský důl glacial cirque in the Krkonoše Mts.
