Asci 8-spored, clavate, K/I–, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum. Ascospores submuriform, with 3 transverse septa and a 1(-2), incomplete longitudinal septa, hyaline, ellipsoid, 27-40 x 14-18 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-.
