Acarospora veronensis A. Massal.

Acarospora veronensis grows in full sun on siliceous rock below 700 m in the Czech Republic. It is common in Europe and infrequent but widespread in North America. It usually has a dispersed thallus of brown areoles not more than 1 mm wide with usually one immersed apothecium, a thin cortex ca. 15 μm thick, and a thin parathecium not wider than 15 μm. It has hymenial gel that turns red in Lugol’s. It can be confused with A. intermedia which has elevated apothecia in a thalline margin but is about the same size and can occur in similar habitats. The name has been loosely used for any small brown Acarospora, some which may be undescribed species.
