Parmelina quercina (Willd.) Hale

The only fertile, non-isidiate Parmelina species in the Czech Republic. It is a relatively thermophilous and light-loving epiphytic lichen that grows mainly on bark of solitary deciduous trees from lowlands (especially on oak) to mountains (on ash and Norway maple). In the past, it occurred sparsely throughout the country, but nowadays it is very rare. In the end of the last century, there was still a number of records, but current data are nearly absent. The species range covers Eurasia, Africa, North and Central America and Australia. Theoretically, especially with the ongoing climate warming, the occurrence of a very similar P. carporrhizans is likely in the country.
