Cryptodiscus gloeocapsa  

Thallus membranous or filmy, ± shining, very thin when dry, pale fawn to green, becoming gelatinous when wet, effuse or vaguely delimited. Photobiont Gloeocystis-like, globose or elongate, in clusters.
Anamorph: conidiomata pycnidia, pyriform, immersed in the thallus. Conidia shortly cylindrical.
Teleomorph: ascomata apothecia, 200-500 µm diam., scattered and discrete or in small clusters, at first immersed and closed, becoming emergent and deeply concave, opening with a broad pore. Disc pale yellow-brown to orange-red, rarely dark brown. True exciple pale yellow-brown to pale brown or concolorous with the disc, 25-70 µm thick. Hymenium 50-60 µm high, yellow-brown in iodine and faint blue in K/I. Interascal tissue of straight ± unbranched paraphyses, not swollen at the apex, immersed within a gelatinous matrix. Asci 40-60 x 4-6 µm, cylindrical, short-stalked, fairly thin-walled, the apex thickened, rounded, K/I+ blue, without any clear apical structures, 8-spored. Ascospores arranged in a fascicle, 20-30 × 1.5-2 μm, narrowly cylindrical to cylindric-fusiform, often tapering at one end, 3- to 4-septate, not constricted at the septa, hyaline, smooth, thin-walled, without an epispore, gelatinous sheath or appendages.
