Lichens of lecanoraceae family in Tarom District, Zanjan Province

The dual identity and structure of lichens was investigated far too late, and they were among unidentified species of nature for quite a while. In spite of comprehensive studies concerning the lichens worldwide, studies in Iran have been limited, while Iran possesses a rich lichen flora due to appropriate geographic and climatic conditions. In recent years, studies concerning the lichens have been the center of attention particularly in the framework of some postgraduate dissertations in different universities, and the lichens of a number of regions in Iran have been collected and identified. Nevertheless, there are not sufficient references and available comprehensive identification keys for lichen species, and the field requires through research. The present paper intends to perform a floristic study of lichens in Tarom district. In this research, following the knowledge of coverage areas, we attempted to carry out a thorough collection of lichens at appropriate distances from different geographic places by random sampling. Following the collection and primary laboratory approaches, identification of genera and species was carried out using designed and available binomial keys. During this study, 7 novel species of Lecanoraceae family including Lecanora, Lecidella and Rizoplaca were introduced.
