Micarea micrococca (Körb.) Gams ex Coppins

A species occurring frequently on acidic bark in both managed and natural forest ecosystems. It is rather a pioneer and relatively shade-loving taxon. Most often, it is found on young trees and twigs. Specimens published from the Czech Republic under this name need to be revised because a number of potentially confusable species, such as M. czarnotae, M. laeta, M. microareolata, M. pseudomicrococca and M. pusilla, have been described recently. The lichen may be mistaken also for pale forms of M. fallax that phylogenetically and chemically falls within the M. prasina agg. In many cases, these taxa cannot be securely distinguished by classical methods without molecular data. However, based on the early observations, M. micrococca s. str. appears to be one of the most common members of the M. micrococca complex.
