Apothecia long-stalked, pin-like, 0.5-1.4 mm high, the stalk 0.04-0.07 mm thick, black, sometimes with a reddish tinge in upper part, the central part of hyaline, strongly swollen, periclinally arranged hyphae, the outer part of reddish brown, intricately interwoven hyphae, often containing droplets of a red pigment. Capitulum black or with a reddish tinge in lower part, hemi- to subspherical, 0.1-0.3 mm across; mazaedium absent. Exciple of reddish brown hyphae; epithecium brownish, thin; hypothecium reddish to yellowish brown, with dark red granules and numerous oil droplets. Asci 8-spored, cylindrical, with a thickened apex penetrated by a narrow canal, formed singly, persisting until the spores are mature. Ascospores 1-septate, pale brown, narrowly ellipsoid, 5-7 x 1.5-2.5 µm, with a poorly pigmented septum and a smooth wall. Pycnidia not rare, stalked, the stalk often branched and forming a tree-like structure with up to 30 pycnidia containing a reddish pigment. Conidia simple, hyaline, with a slightly truncate proximal end, 2-2.5 x c. 1 µm. Photobiont absent. Spot tests: all red-pigmented parts of thee ascomata and pycnidia K+ persistently green. Chemistry: an unidentified red pigment.
