Atla wheldonii (Travis) Savić & Tibell

A tiny pyrenocarpous lichen characterised by dark brown muriform spores, perithecia without involucrellum and inconspicuous thallus. As the only one species within the genus, it does not grow on rocks but on basic humid soil, bryophytes and plant debris in both natural and anthropogenic habitats in initial succession stages at higher elevations. The species is reported rarely from Europe, but it is probably overlooked. In the Czech Republic, data about its occurrence was first published as late as in 2009, when it was found in a waste pond near Radvanice in the Trutnov region (Peksa 2009). Furthermore, it has been recorded in the foothills of the Krkonoše Mts, in the Zlatohorská vrchovina uplands and in the Krušné hory Mts (see Bouda et al. 2019), all the records are from abandoned quarries or mines and their spoil heaps.
