Ascomata apothecia, 2-3 (-4) mm diam., erumpent through the bark in clusters, initially closed, opening into uneven discoid structures, lacking a stipe, the outer surface leathery and sometimes inconspicuously striate, dark brown when hydrated and yellow-brown when dry with a ragged pale cream or white edge. Interascal tissue of filiform paraphyses, the apices clavate to ca 4 µm diam., with a light brown encrustation. Asci 75-80 x 8-9 μm, cylindric-clavate, fairly thick-walled but not fissitunicate, with a rounded to almost truncate apex, 8-spored.
