Melanohalea infumata (Nyl.) O. Blanco & al.

One of the rarest Melanohalea species of the Czech Republic. It is a saxicolous lichen, differing morphologically from the epiphytic M. elegantula only in pruina on its thallus. Melanohalea infumata has an arctic-alpine distribution and grows on siliceous rocks in Scandinavia, Central European mountains and in the North America. The species is known from a single locality in the Czech Republic, Petrovy kameny in the Hrubý Jeseník Mts, where it is known since the first half of the last century up to now. M. infumata probably does not occur in the Alps (Nimis et al. 2018), but is probably confused with saxicolous M. elegantula agg. by the central European authors. Apparently, the group requires further studies.
