Ascomata apothecia, to 10 (-15) mm diam., scattered or aggregated, sessile, ± discoid, fleshy, the hymenium orange to red, the external surface orange and scurfy, covered with ± hyaline to pale yellow-brown unbranched hairs (170-) 300-800 µm long and 20-40 µm diam., the base slightly constricted and usually lobed or shortly bifurcate and the apex acute. Peridium composed of globose thin-walled cells to 25 µm diam. Interascal tissue composed of unbranched paraphyses to 3.5 µm diam., containing orange carotenoid pigments, the apex clavate, to ca 10 µm diam. Asci 180-220 x 10-13 µm, cylindrical, with a tapering stalk, the apex rounded to truncate, fairly thin-walled, operculate, not staining in iodine, 8-spored. Ascospores arranged ± obliquely uniseriately, 14.5-18 x (7.5-) 8-9.5 µm, cylindric-ellipsoidal, aseptate, hyaline, smooth, fairly thin-walled, with an epispore that sometimes becomes detached when warmed in lactic acid.
