All specimens were examined and their accession numbers and herbaria where deposited are given in parentheses after the locality numbers. The material was examined using standard microscopic techniques. Specimens were managed according to Obermayer 2002 and identified by examination of their morphological characteristics with a dissecting microscope according to valid references (Dobson 2011; Malcolm & Galloway 1997; Ryan et al. 2002). Anatomical features were studied by preparing thin sections of the thallus and fruiting bodies. Moreover, the chemical characters were studied by using spot tests. In special cases, thin layer chromatography was performed. The employed principal identification keys were as follow : Awasthi 1991; Gaya 2009; Krzemińska 2012; Nash et al. 2002, 2007; Sliwa 2007; Smith et al. 2009; Temina et al. 2005.. The species names were checked against Index Fungorum (http://www.speciesfungorum.org/ names/names.asp) and Mycobank (Crous et al. 2004) to ensure their orthography.

On calcareous rocks; L: 4 (Ghiyasi 200, ICH); 8 (Ghiyasi 244, ICH); 10 (Sohrabi 31571, ICH). Recently, this species was reported from Kerman province by (Ghiyasi et al., 2019). Here some additional specimens were examined from different localities and the occurrence of species was formally confirmed. Widely distributed in the eastern Mediterranean regions, and possibly some lichen elements of the Irano-Turanian and Saharo-Arabian phytogeographical regions. See (Galun, 1970; Galun and Garty, 1972).
Acarospora bullata Anzi
On calcareous rocks; L: 3 (Ghiyasi 207, ICH). This species is very common in Iran and reported (Golubkova, 1988, 1981; Lotfian et al., 2016; Magnusson, 1929; Müller, 1892; Seaward et al., 2008, 2004; Szatala, 1940). According to Knudsen et al., 2010, this species is very similar to A. rugulosa in North America and their separation requires further study.
Acarospora cervina A. Massal.
On sun-exposed calcareous rocks; L. 6 (Ghiyasi 223, ICH). a widespread, probably holarctic species (Nimis, 2016) reported from different parts of Iran, see (Barkhalov, 1975; Calatayud et al., 2007; Magnusson, 1929; Moniry et al., 2005; Müller, 1892; Seaward et al., 2004; Sohrabi, 2005a, 2005b) Known from: East Azerbaijan, West Azerbaijan, Kordestan, Fars, Tehran, Golestan, Razavi Khorasan, Lorestan, Gom, Markazi, Zanjan, Yazd. This is a widespread species in Asia and Europe and North America with a Holarctic distribution in the southern part of the temperate zone (Nimis, 2016). According to Amrani et al., (2018), this species has a wide distribution in Iran and worldwide, so far known from Africa (incl Madagascar), Oceania – Australasia, Eurasia, Europe, North America and Arctic (GBIF, 2019).

Anamylopsora pulcherrima(Vain.) Timdal
On sun-exposed calcareous rocks; L: 7 (Ghiyasi 227, ICH). This species was recently reported from Kerman province by Ghiyasi et al., (2019) and also previously reported from a few localities in West Azerbaijan, Razavi Khorasan and North Khorasan provinces by Seaward et al. (2008).

Anaptychia mereschkowskii (Tomin) Kulakov,
Syn: Anaptychia desertorum (Rupr.) Poelt
On calcareous rocks; L: 1 (Ghiyasi 215, ICH); 2 (Ghiyasi 629, ICH); 6 (Ghiyasi 631, ICH); 7 (Ghiyasi 633). This species was recently reported from Kerman province by Ghiyasi et al., (2019 as A. desertorum (Rupr.) Poelt) and previously reported from different parts of Iran (Oxner, 1946; Seaward et al., 2008; Szatala, 1940).
Aspicilia caesiascens Pišút
On calcareous rocks; L: 1 (Ghiyasi 627, ICH); 4 (Ghiyasi 216); 7 Ghiyasi 250). This species seems to be limited to the Irano–Touranian phytogeographical region, it was reported from Uzbekistan by Pišŭt (1978) and from Iran bySeaward et al., (2008) and Vězda (1979). Aspicilia caesiascens is a very unusual species because it is an umbilicate growth from, very different from crustose Aspicilia sensu (Nordin et al., 2010). Unpublished molecular data show that it belongs to the genus Lobothallia. This group was revised by Sohrabi et al. in an ongoing project and their result will be published soon.
Aspicilia determinata (H. Magn.) N. S. Golubk.
The presence of this species in Iran needs confirmation. Unfortunately, the voucher specimen of this species was not available for this study. In an ongoing revision of the genus Aspicilia sensu lato in Iran, we were so far unable to confirm the presence of their species in Iran and we consider this record as a doubtful one.
Calogaya biatorina (A. Massal.) Arup, Frödén & Søchting
On calcareous rocks; L: 6 (Ghiyasi 220 sub Acarospora interrupta, 221, ICH).

Basionym:Lecanora calcarea var. excrescens J. Steiner, Annales Mycologici 8 (2): 223 (1910) [MB#457469]. Aspicilia excrescens (J. Steiner) Szatala, Ann. Mus. Nat. Hungar. n.s. VIII (1957), p. 126[MB#364357].
Known only on calcareous rocks in arid regions of Iran; L: 5 (Ghiyasi 205, ICH). This was reported by (Steiner, 1910) as Lecanora calcarea var. excrescens.

These new findings not only contribute to the knowledge of lichens in Kerman province in SE Iran, but also widen the knowledge on the world distribution of some poorly known lichens. Some of the species reported here including Anamylopsora pulcherrima, Candelariella plumbea and Circinaria straussii are very rare and known from very few localities in Iran. Our observation on lichens of Kerman confirms that despite ca. 190 years from the first report on Iranian lichens by Göbel (1830), it is still poorly investigated. In Iran and particularly in Kerman province, there are two reasons for this weakness. First, there is no resident lichenologist, who could collect and study lichens in Kerman intensively. Second, the topography, phytogeography, geology, and climate of the country including Kerman Province is extremely variable. For example, the climatic diversity of Kerman varies from hot to cold, extremely dry to very dry, and a countryside where nears steppe, semi-arid, to desert climates, which is rare and unique in this respect. Kerman province has several high mountains, where their peaks rising are following: Mt. Bahraseman, 3886 m; Mt. Pelvar, 4233 m; Mt. Jupar, 4135 m; Mt. Lalehzar, 4351 m. Around these mountains, many large steppe-mountain regions with a rocky topography and covered by rather natural endemic vegetation; the presence of montane and alpine areas with intrusive (igneous) rock substrates is especially important for the total lichen diversity.
In the present study, the number of 59 lichenized fungi belonging to 14 families are reported: Teloschistaceae (9 taxa), Acarosporaceae (9 taxa), Megasporaceae (7 taxa), Verrucariaceae (6 taxa), Lecanoraceae (6 taxa), Physciaceae (5 taxa), Lichinaceae (4 taxa), Candelariaceae (3 taxa), Ramalinaceae (4 taxa), Rhizocarpaceae (2 taxa), Graphidaceae (1 taxon), Baeomycetaceae (1 taxon), Collemataceae (1 taxon) and Squamarinaceae (1 taxon). As to substrate diversity, 49 species are epilithic or saxicolous, 5 epigeic or terricolous and 3 epiphytic growing on bark or mosses. Our result certainly emphasizes the great importance of Kerman province within the Iranian lichen flora and thereby, justifies the high level of attention to this poorly known area. Further field studies updating and supplementing the presented list should be performed. Remarkable point is the low number of epiphytic and terrestrial lichens. This issue probably reflects the very dry climate, even though the visited localities were laying at elevations between 1500-2500 m.
