Micarea nitschkeana (J. Lahm ex Rabenh.) Harm.

An inconspicuous microlichen from the M. denigrata group. In the Czech Republic, it occurs mainly in coniferous, both managed and natural, mountain forests. Its usual substrate are thin twigs, dead or alive. It grows also on wood of snags, cutting surface of stumps and exposed roots of uprooted trees. The species can be confused with richly fertile abnormally developed specimen of the ubiquistic M. denigrata. These two taxa are not always easily distinguishable from each other.
