Basionym: Baeomyces ceratites Wahlenb., Flora Lappon.: 459 (1812).
Photobiont: Green alga.
Chemistry: Siphulin, in short-wave UV pale spot with low Rf, becoming yellow; UV+ dull brownish after treatment with acid and heat. Sometimes together with traces of siphulin-like compounds. These compounds are concentrated mainly in the cortex or outer parts of the medulla, hence the spot test reactions are best carried out on the cortex. Cortex and medulla P-, K+ yellow-orange, KC+ fleeting violet, soon yellow-orange, C+ fleeting violet, soon yellow-orange, UV- pale-yellowish
