Taxonomic investigations on lichens growing in and around Mezits (Bursa)

In this study, it was aimed to determine the lichen diversity of the region by making species identifications with the help of various determination keys of lichen samples taken from substrates such as trees, shrubs, rocks and soil at stations determined in the valley and forest areas in and around Mezitler. Between 07.08.2018 and 01.08.2019, 414 lichen samples were collected from 39 localities and it was determined that the identified samples were 76 lichen taxa under 43 genera belonging to Ascomycota. It was determined that 4 of the identified taxa were new records for Turkey and 6 were new records for Bursa. Species that are new records for Turkey; Arthonia arthonioides (Ach.) A.L. Sm. 1911, Lecanora helicopsis (Walenb.) Ach. 1814, Pseudosagedia borreri (Trevis.) Hafellner & Kalb 1995, Verrucaria cernaensis Zschacke 1927. Species that are new records for Bursa; Farnoldia jurana (Schaer.) Hertel 1983, Lecidea helvola (Körb. ex Hellb.) Th. Fr. 1874, Lecidella euphorea (Flörke) Kremp. 1861, Lepraria caesioalba (B. de Lesd.) J.R. Laundon 1992, Verrucaria elaeomelaena (A. Massal.) Arnold 1868, Verrucaria viridula (Schrad.) Ach. 1803.
