P. isidiigera is also new to Asia. Keywords — Ascomycota, biodiversity, Konya, Uşak, Heybeliada Introduction Studies on the lichen flora of Turkey are not as extensive as elsewhere, and so the lichen flora is relatively poorly known. Recently, however, many new lichen taxa have been recorded for Turkey (Candan & Özdemir Türk 2008, Yazici et al. 2008a,b, Yazici & Aptroot 2008). Tree species new to Turkey are described below. Materials and methods Te present report is based on collections from three different provinces (Konya, İstanbul and Uşak) made between 15–20 August 2007. Air-dried lichen samples were examined using stereo and light microscopes. Secondary metabolites were identified by the usual spot tests (Brodo et al. 2001; Esslinger 1994, 2000; Mayrhofer 1988;, Purvis et al. 1992; Torrente & Egea 1989). Vouchers are stored in the herbarium of the Biology Department, Faculty of Sciences and Arts, Karadeniz Technical University, Trabzon, Turkey (KTUB). Species Lecania spadicea (Flot.) Zahlbr. Specimen examined: Konya: Seydişehir, main roadside to Seydişehir, 37º28’20”N, 31º49’30”E, on calcareous rock, 1130 m, 15 August 2007, Yazici 1557.
