Macrolichens new to Algeria and other interesting species from Theniet-el-Had National Park

摘要

This work is the first inventory of the macrolichens of Theniet-el-Had National Park in western Algeria, the oldest in Algeria with beautiful forest and ancient cedar stands. Seventy macrolichens were observed. Lichenomphalia umbellifera and Umbilicaria nylanderiana are new to North Africa; Hypocenomyce scalaris, Hypogymnia tubulosa, Melanohalea elegantula, Melanohalea laciniatula, Parmelina pastillifera, Ramalina capitata (var. capitata, digitellata and protecta), and Protoparmeliopsis muralis var. diffracta are new to Algeria. Many lichen species, which are usually sterile or whose apothecia are very rarely observed in the literature, are fertile in this study area, e.g. Parmelina tiliacea, Physcia adscendens, Phaeophyscia orbicularis, Platismatia glauca and Pseudevernia furfuracea.
