Chaenotheca chlorella (Ach.) Müll. Arg.
Mém. Soc. Phys. Hist. Nat. Genève, 16: 360, 1862. Basionym: Calicium chlorellum Ach. - Meth. Lich.: 89, 1803.
Synonyms: Calicium phaeocephalum var. flavum Harm.; Chaenotheca carthusiae (Harm.) Lettau; Chaenotheca suzai Nádv.
Description: Thallus crustose, usually well-developed and episubstratic, ecorticate, verrucose to minutely granular, green to grey-green. Apothecia short-stalked, pin-like, shining black but covered in a bright yellow pruina at least in the upper part of stalk and the lower side of capitulum. Stalk 0.7-1 mm high, 0.05-0.08 mm thick, of periclinally arranged, medium brown hyphae. Capitulum broadly obovoid to lenticular, with a more or less well-developed excipulum of periclinally arranged hyphae, continuous with the stalk tissue. Mazaedium well-developed, brown; hypothecium medium brown, with a strongly convex upper surface. Asci cylindrical, clearly stalked, formed singly, dissolving early, with uniseriately arranged ascospores. Ascospores 1-celled, brown to pale brown, globose to broadly ellipsoid, 4.5-9 x 3-4 µm, the wall with a rough ornamentation of irregular cracks. Photobiont chlorococcoid, with rectangular cells (Stichococcus) or rarely trebouxioid. Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus without lichen substances; yellow pruina consisting of vulpinic acid.
