Description: Thallus crustose, mostly endosubstratic and inconspicuous, effuse, whitish grey to pale grey-green. Perithecia rather rare, 0.15-0.25 mm across, globose to subconical, at first immersed, later more or less superficial. Exciple brown and 30-50 μm thick in upper part; paler and thinner in lower part, of cellular hyphae, usually without bark cells; involucrellum poorly developed, apical, K+ green; hamathecium of slender, branched and anastomosing, long-celled, c. 1 μm thick pseudoparaphyses; periphyses absent; hymenial gel I-. Asci 8-spored, cylindrical, K/I-, fissitunicate, the apical dome with an indistinct ocular chamber. Ascospores 1-2(-3)-septate, hyaline, clavate-fusiform, the part above the primary septum wider and about twice as long as the lower part, (12-)14-20(-23) x (3-)4.5-5(-6) μm. Pycnidia black, prominent, of two types: a) 0.1-0.15 mm across, to 0.2 mm high, sessile, conical, extruding a white, thread-like, very long gelatinous cirrus containing ellipsoid or ovoid macroconidia with a truncate base, measuring 3.5-4.5 x 1.8-2 μm, or 7.5-10 x 3.5-4 μm. b) 0.05-0.1 mm across, mostly immersed, globose, with rod-shaped to narrowly ellipsoid microconidia measuring 2.3 x 1-1.3 μm. Photobiont trentepohlioid. Spot tests: all negative. Chemistry: without lichen substances.
Note: a mild-temperate, perhaps holarctic species, mainly found on Sambucus along rivers and brooks. Overlooked for a long time, and certainly more widespread throughout Italy, with optimum in the submediterranean belt. For further information see Aptroot (1999).
