The genus is mainly lichenicolous but with green algae on rocks or tree bark and seldom on mosses. Sexual morph: Ascomata perithecial, pyriform (pear-like), astromatic, immersed. Ostiole periphysate. Peridium hyaline with ostiolar region appearing light brown at times. Asci 4-8-spored, unitunicate, clavate, closely ellipsoid to ovoid, short-pedicellate, with barely visible apical ring, deliquescent at the base. Ascospores overlapping 1–2-seriate, hyaline, aseptate, smooth-walled, fusiform to limoniform or ellipsoid, lacking any mucilaginous sheath or appendage.
