Mycotaxon, 55: 383, 1995. Basionym: Lichen melanocarpus Sw. - Nov. Gen. Sp. Plant.: 147, 1788.
Synonyms: Sphaerophorus compressus Ach.; Sphaerophorus melanocarpus (Sw.) DC.

Description: Thallus fruticose, shrubby-coralloid, 3-5 cm high, often forming extensive mats; branches highly divided in upper part, flattened towards the base, ending with small, subterete, palmate branchlets, pale greenish to greenish grey, sometimes partly pinkish brown, the surface smooth or transversally cracked in old branches. Apothecia rare, developing on the underside of larger, terminal, fertile branches, 1.5-3.5 mm across, globose, with a black mazedium. Thalline exciple soon excluded. Asci cylindrical, with uniseriately arranged spores, disintegrating before the spores are mature. Ascospores subglobose, at first hyaline, then pale to dark grey, 7-9 µm in diam. Pycnidia terminal, black to brown. Conidia bacilliform to rod-shaped, 3-8 µm long. Photobiont: chlorococcoid. Spot tests; medulla K+ yellow, C-, KC-, P+ orange, UV+ blue-white. Chemistry: sphaerophorin and stictic acid complex, the latter most abundant in the apothecia.
