Descriptions
Chaenotheca ferruginea (Turner ex Sm.) Mig.
Thallus immersed, or usually episubstratic, granular to verrucose, palegrey or whitish, often with limited yellow to reddish patches turning deep red in K. Photobiont: . Apothecia epruinose, short or long, 0.8-1.7 mm high, 7-19 times as high as width of stalk. Stalk 0.07-0.15 mm diam., shining, black, epruinose. Capitulum broadly or narrowly obconical, with well-developed excipulum. Excipulum 0.23-0.47 mm diam. Hypothecium obconical with convex surface. Capitulum without pruina. Asci cylindrical to narrowly clavate, 14-18 × 2.7-3.3 µm well-stalked, spores uni-or biseriate. Usually asci are formed singly but sometimes two asci join into a short chain. Ascospores spherical, 5.6-7.7 µm diam., when mature provided with coarse and irregular fissures. Chemistry: The thallus of frequently contains a yellow-red pigment, which is often concentrated in distinct patches. The pigment is K+ dark red and probably of quinonoid nature. A yellowish, K+ red pigment also occurs in the mazaedium and often gives the mazaedium a strikingly yellow tinge. Parts of the thallus without the yellow pigment are K-, KC-, C- and Pd-.
