Lecidea grisella Flörke

After many decades, this taxon has started to be distinguished again from L. fuscoatra at the species level (Aptroot & van Herk 2007). Both these common lichens contain gyrophoric acid but differ in the character of the thallus, which is rimose in L. grisella and composed of separate areoles in L. fuscoatra. Lecidea grisella was not distinguished in the past, and often still is not, so the actual number of occurrences in our area is likely to be higher than the data collected so far suggest. Still, it is rarer species than L. fuscoatra which has very similar ecological requirements and distribution.
