Description: Thallus leprose, episubstratic, brownish orange to ochraceous yellow-orange, entirely consisting of scattered to contiguous, c. 0.1 mm thick soredia-like, globose, granules, forming an up to 0.8 mm thick, poorly delimited, not lobate crust. Apothecia absent. Pycnidia not observed. Photobiont chlorococcoid. Spot tests: thallus K+ red, C- KC-, P-, UV+ orange. Chemistry: thallus with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
Note: a temperate to humid subtropical species found on shaded, steeply inclined or underhanging surfaces of calciferous rocks, sometimes also overgrowing epilithic mosses or even occurring on the undersides of inclined old trunks of trees with base-rich bark; certainly ranging throughout the country, below the subalpine belt.
Growth form: Leprose
Substrata: rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
