NEW LICHEN RECORDS FROM TURKEY

Three lichen species, namely Cladonia grayi G. Merr. ex Sandst., Pertusaria subventosa Malme var. subventosa, and Parmelia squarrosa Hale are reported as new to Turkey as a result of a lichenological survey in the Burdur region of the country. Descriptions are presented, including geographic distribution, substrate, chemistry, and comparisons with morphologically similar taxa. Introduction Although many lichen taxa have recently been recorded for Turkey (Aptroot and Yazici, 2009, 2012; Arslan et al., 2011; Candan and Halıcı, 2011; Karagöz et al., 2011; Karagöz and Aslan, 2012; Kınalıoğlu and Aptroot, 2011; Osyczka et al., 2011; Vondrák et al., 2012; Yazıcı et al., 2010a, b, c), the lichen biota of Turkey is still incompletely known, as is in many parts of the world. Therefore, more studies are needed to achieve a complete lichen flora of Turkey. Burdur in Turkey has a continental Mediterranean climate with cold, snowy winters and very hot, long and dry summers. The mean annual temperature is 15oC and the temperature ranges from -16°C to 39°C. The mean annual rainfall is about 468 mm and the average humidity is 51.2% (Akman, 1999). Only 25 lichenized fungi have thus far been reported for this region (Çobanoğlu, 2005; Öztürk et al., 2005; Pišút and Guttová, 2008; Şenkardeşler, 2009). The visited areas, Bucak, and Altınyayla districts, are mountainous with much forest dominated by Abies, Cedrus, Ficus, Fraxinus, Juniperus, Olea, Pinus, Pistacia, Prunus, Quercus (especially Altınyayla district), Rhus species and alternating streams, lakes, dams (e.g. Yapraklı Dam in Altınyayla district and Karacaören dam in Bucak district) (Baytop and Denizci, 1963). The underforest flora is very abundant in these areas where the bedrock consists mainly of marble. This paper presents first reports of lichenological exploration in the region of Burdur, southwestern Turkey. Materials and Methods Lichen samples were collected on 28 29 June 2012, air-dried and examined with a Nikon SMZ1500 stereomicroscope and a Nikon Eclipse 80i compound light microscope. For the identifications relevant keys were consulted (Archer and Elix, 1993; Brodo et al., 2001; Goward, 1999; Messuti et al., 2007; Smith et al., 2009). Thin Layer Chromatography (TLC) analyses were carrried out when needed for Cladonia grayi and Pertusaria subventosa var. subventosa (Orange et al., 2001). Vouchers are stored in the Herbarium of the Biology Department, Karadeniz Technical University, Trabzon, Turkey (KTUB). The descriptions are based on Turkish specimens and completed with data from the indicated literatures (Archer and Elix, 1993; Brodo et al., 2001; Dobson, 2005; Duncan, 1970; Goward, 1999; Hale, 1973; Hyvönen, 1985; Wirth, 1995).

This paper presents first reports of lichenological exploration in the region of Burdur, southwestern Turkey.
Habitat: Cladonia grayi is a holarctic species, found on soil rich in humus, more rarely on conifer wood, peat, dead leaves, turf, rotting wood, mosses over mineral soil.
Distribution: Costa Rica, North America, Japan, Spain, Italy, Russia, Germany, the Netherlands, Norway, Estonia, Finland, New Zealand and USA.New to Turkey.
Notes: Cladonia grayi is similar to C. chlorophaea (Flörke ex Sommerf.)Spreng., and Cladonia merochlorophaea Asahina but C. grayi has podetia with few detachable microsquamules on the lower half, while these occur abundantly in C. merochlorophaea.The presence of fumarprotocetraric acid together with grayanic acid in C. grayi helps to distinguish it from C. chlorophaea with the exclusive presence of fumarprotocetraric acid (Goward, 1999;Smith et al., 2009).Accompanying species: Cladonia humilis.
(Fig. 2a,b).Thallus foliose, adnate or ± adnate on its substrata, whitish-grey, greenish or greenish-grey; lobes divaricate, contiguous or imbricate, 0.7-2.5 mm wide.Upper surface plane or foveolate with laminal and marginal pseudocyphellae forming a reticulate network; isidia present, fine and cylindrical, up to 0.5 mm tall and becoming more concentrated in older central areas of the thallus and marginal parts of the lobes.Rhizines squarrose, but mostly simple at the margins of lobe.Apothecia absent.Cortex K+ yellow, medulla K+ yellow turning red, C-, P+ orange.[Some morphological characters taken from Hale (1971)].
Habitat: Parmelia squarrosa commonly grows as epiphyte on deciduous and coniferous trees near the coast and rarely on rock and decayed wood.
Distribution: Mostly found in oceanic areas in temperate and boreal regions.Distributed in America, Asia (Japan, China, Korea, Nepal, Russia), Canada and Europe (the Alps of western Austria and southern Switzerland).This species is new to Turkey.
