Micarea denigrata (Fr.) Hedl.

An ubiquistic lichen, usually occurring as one of the pioneer species on hard, worked timber (fences, railings, bridges, etc.) in rather sun-exposed anthropogenic habitats, where it may become one of the dominant species, for example in a company of Trapeliopsis flexuosa. It also grows on hardwood of snags and stumps in old-growth and managed forests (in forest openings and clearings). Less often, it may be found on a tree bark and exceptionally on recently exposed siliceous stones on the ground. On the lately mentioned substrate, it may be mistaken for M. confusa from which it differs only in conidia. Micarea denigrata is widespread from lowlands to mountains across the Czech Republic. It is resistant to pollution and tolerant to even slight eutrophication of the environment.
