Perithecia rarely numerous, black, scattered, 0.15-0.25 mm diam.. Pycnidia numerous, black, 0,1-0,2 mm of two types: 1) conical, 2) conical and ended by peg-like tips or upside-down funnel-shaped appendix, with ellipsoid or ovoid macroconidia, extruded as a white tendril in which the conidia are bound by a gelatinous matrix. Spores ellipsoid, 1- to 3-septate,  15-20 x 4-5 µm. Photobiont : Trentepohlia.  Chemical spot tests negative.
