Abstract
One hundred and ten lichenized and three non-lichenized fungi are reported from southeastern Europe, mostly from the Balkan Peninsula. Caloplaca phaeothamnos is new to Europe.
Caloplaca brachyspora, Chaenotheca cinerea, Gyalecta liguriensis, Peltula placodizans, Pleurosticta koflerae, Polyblastia forana, Protoparmelia oleagina, Protoparmeliopsis achariana, P. vaenskaei and Verrucaria breussii are new to southeastern Europe. New country records are reported for Albania (57 species), Bosnia and Herzegovina (4), Bulgaria (15), Croatia (3), Greece (14), Kosovo (6), Montenegro (1), North Macedonia (5), Romania (1) and Serbia (12).
Many of these records are from old-growth and primeval forests. They underline the high potential for nature and biodiversity protection of many localities on the Balkan Peninsula.
