Distribution: N - TAA (M 0033500, type).

Description: Thallus not apparent (species not lichenized), mostly reduced to small, obconical to cylindrical, bright yellow-pruinose fruiting warts. Ascocarps frequent, apothecioid, rounded, semi-immersed in the warts, 0.1-0.2 mm across, with a flat to concave, finally exposed, yellow-pruinose disc. Hymenial gel I+ red, K/I+ blue; paraphyses simple, slender, longer than the asci. Asci many-spored, spindle-shaped, the wall I+ blue in upper part, the apex thickened into a tholus with a I+ blue ring-structure within. Ascospores 1-celled, hyaline, globose, 4.5-6 μm wide. Pycnidia small, yellow, flask-shaped. Conidia 4-6 μm long. Photobiont absent. Spot tests: apothecia K-, C-, KC-, P-. Chemistry: yellow pruina with pulvinic acid derivatives.

Note: an ephemeral early coloniser of different substrata, including the thalli of other lichens, mostly in upland areas.
