Anamorph: not known in nature. Teleomorph: Stromata absent. Ascomata apothecia, (1.5-) 5-25 mm diam., discoid to shallowly cupulate, sessile, the disc surrounded by stiff brownish to black spinose hairs that frequently also clothe the outer wall. Ectal excipulum of globose to angular cells, often becoming elongate at the margin to form short broad hypha-like hairs. Medulla compact, composed of intertwined hyphae. Setae originating from internal tissues and projecting through the outer layer of the ascoma, sometimes up to 3 mm in length, the base simple, bi- or trifurcate, thick-walled, septate, rarely branched, sometimes accompanied by superficial hairs formed from the outermost cells of the excipulum. Hymenium bright red or orange, fading to white or buff when dry. Interascal tissue of simple or branched paraphyses that may be longer than the asci, the apices often enlarged, globose or pyriform, containing orange carotenoid pigments. Asci ± cylindrical, fairly thick-walled but not fissitunicate, arising from croziers, operculate, not blueing in iodine, usually 8-spored. Ascospores arranged uniseriately, globose to ellipsoidal, ± hyaline, aseptate, almost always ornamented with spines, warts or reticulae (sometimes inconspicuous), sometimes with a separable outer layer (perispore) bearing the ornamentation.
