Despite the long history of lichenological research in Azerbaijan, the flora of lichens in the Kur-Araz lowland has been studied poorly. Since the literary sources contain only partial information about the lichens of the investigated lowland, the aim of our work was to establish the taxonomic composition of this region. Preliminary information on lichens of the Kur-Araz lowland is given in the work. The list includes a total of 56 taxa belonging to 40 genera, 17 families and 4 classes of the Ascomycota section. 16 species from the above-mentioned list are new for the Kur-Araz lowland i.e. Alyxoria varia , Anatychia cilirais , Arthopyrenia subcerasi , Candelariella vitellina , Cetraria aculeata , Collema tenax, Flavoplaca citrina , Lecanographa amylacea , Lecanora crenulata , Lepraria incana , Parmelia ryssolea , Phaeophyscia hirsuta , P. orbicularis , Romjularia lurida , Tephromela atra, Xanthoparmelia conspersa . Information regarding the location in the studied area, substrate and belonging to the ecological group was given for each species. Among the identified lichens, the largest number of species is found in crustose lichens (24 species or 44% of the total species number), foliose lichens (15 species /28%), fruticose (8 /15%) and squamulose lichens (7 /13%). Depending on the hydric factor, six groups were distinguished such as hygromesophytes, mesophytes, mesophytes-xeromesophytes, xeromesophytes, xerophytes and xerophytes-cryophytes. Each of hygromesophytes, mesophytes-xeromesophytes, xerophytes-cryophytes groups is represented by one species only. The group of xeromesophytes includes 2 species from 2 genera and 2 families; the mesophytes group introduces 19 species from 14 genera and 6 families. The group of xerophytes is represented by the largest number i.e. 28 species from 21 genera and 14 families which reflects the ecological features and climatic conditions of the studied area.
