Sarcogyne cyclocarpa (Anzi) Steiner

Sarcogyne cyclocarpa occurs only on calcareous rock and otherwise looks like the common Acarospora privigna (illegitimate name Polysporina simplex) which occurs on siliceous rock. It differs in often having slightly wider ascospores than A. privigna (2.0–2.5 µm vs. 1.0–2.0 µm).

It occurs in Europe, Asia (at least Afghanistan and Pakistan), and eastern North America. It is apparently rare in Czech Republic, only known from a single historical record from limestones in the Obří důl glacial cirque in the Krkonoše Mts (Migula 1929–1931).
