Thallus: not developed. Anamorph: not known. Teleomorph: ascomata apothecia, mazaedial. Stalk 500-800 µm tall and 60-100 µm diam., dull grey to pale brown when mature, composed of infrequently branched parallel hyphae with a distinct brown core. Young ascomata faintly yellow-pruinose, the pruina often degenerating by maturity when the ascomata appear pinkish to reddish-brown with a pale pinkish to yellowish-brown mazaedium, often cracking irregularly when dry. Hymenium 200-300 µm diam., hemispherical to lenticular, with the excipulum not forming a distinct collar surrounding the stalk at the base of the fertile head. Interascal tissue absent. Asci 20-25 x 2.5-3 µm, cylindrical to cylindric-clavate, short-stalked, thin-walled and evanescent, without apical structures, 8-spored. Ascospores arranged uniseriately or partially biseriately, 3-3.5 (-4.5) µm diam., ± globose but rather variable in shape, hyaline (pale brown en masse), almost smooth-walled (light microscopy), with an irregular cracked ornamentation (SEM; Amo & Burgaz 2004). Chemistry: no lichen substances detected.
