Montanelia disjuncta (Erichsen) Divakar, A. Crespo, Wedin & Essl.

A widespread saxicolous species that prefers sun-exposed steep surfaces of acidic siliceous and volcanic rocks. It occurs sparsely from uplands to mountains across the Czech Republic. In Europe, it is common from temperate to boreal regions.

Historical distribution of M. disjuncta needs a revision since in the past, it did not used to be distinguished from the similar M. sorediata, from which it differs in soralia formed mainly on the lobe surface, the presence of pseudocyphellae on lobe margins and often also by shiny thallus. Another similar arctic-alpine to boreal-montane lichen M. tominii may be found in Central European mountains (e.g. in the Alps). It differs in prominent pseudocyphellae and a C+ red reaction of medulla. Its presence in the Czech Republic is theoretically possible.
