Diversity and ecology of the lichen family Lobariaceae (lichenized Ascomycota: Peltigerales) in Croatia

The Lobariaceae is the second largest lichen family in the Ascomycota. In Croatia, findings of five species were recorded, namely: Lobaria pulmonaria, Lobarina scrobiculata, Ricasolia amplissima, Ricasolia virens and Sticta fuliginosa. Data about locations and habitats were collected from literature, by checking at herbaria collections in Croatia and abroad, and from the records of recent field surveys. Distribution maps has been produced for each species. All studied species belong to the epiphytic alliance Lobarion pulmonariae. Distribution maps show frequent distribution in the montane belt of the Dinaric Mountains, and in the Middle and southern Dalmatia, with a disjunctive distribution in the montane and lowland belt in the Pannonian region. Distribution of the species is matching the areas in Croatia with mean annual precipitation above 1, 000 mm. The main substrates are Fagus sylvatica, Acer pseudoplatanus, Quercus pubescens, Quercus ilex, Picea abies and Abies alba. Mean host tree circumference ranged 106- 179 cm, with maximum 390 cm. Bark pH was in optimal range (5.8-6.9). Nowadays, in some parts of Croatia, big and fertile thalli of Lobaria pulmonaria, Lobarina scrobiculata and Ricasolia amplissima can still be found. The number of findings of Ricasolia virens is small, since it was discovered in 2002. For Sticta fuliginosa, there was only one historical record from 1869, up to recent discovery in 2008. Conservation measures are related to forest management practice.
