INTRODUCTION
In spite of a number of new species of the genus Caloplaca were recently described (Kondratyuk et al. 1996, 2004a, 2007, 2009a, b, 2010, 2011a, b, 2012b; Lumbsch et al. 2011; etc.) there is a number of taxa, which are still out of the published keys (Kondratyuk et al. 2004b, 2012a).
The aim of this paper is to present valid description of the next five species recently found in various regions of Asia.
MATERIALS AND METHODS
Materials of representatives of the Teloschistaceae were revised in the following herbaria: KW-L, KoLRI, LD, MSK-L, SAKH, VBGI.
TAXON DESCRIPTIONS
Caloplaca austrocoreana S. Y. Kondr., L. Lokos et J.-S. Hur, spec. nova (Fig. 1)
Similar to Caloplaca albovariegata, but differs in having regular cortical layer of thallus, in having lower hymenium, in having narrower ascospores and wider septum, in having distinctly bluish epihymenium and bluish lateral true exciple; and in the lack of reaction with K in thalline cortex and lateral outermost part of true exciple.
Type: South Korea: Jeollanam-do, Yeosu-si, Nam-myeon, Yusong-ri, Geumoh-do, on rock. Lat.: 34[degrees] 31' 55.03" N; Long.: 127[degrees] 45' 55.05" E; Alt.: 11 m a.s.l. Coll.: U. Jayalal, J. S. Park and J. A. Ryu (120513), 27.04.2012. Holotype: KoLRI 015504; Isotypes: KoLRI 015502, the same locality, growing together with Buellia, Dimelaena, Verrucaria, Lecanora (120511); KoLRI 015506 (sub Phaeophyscia exornatula), the same locality (120515-1); KoLRI 015515, the same locality (120523).
Thallus 3-4 cm across, very smooth in peripheral zone to areolated in the centre; grey to grayish white with brighter white soralia, sometimes coalescing in places; cracked or areolate, areoles small (0.2-)0.5-0.7 mm across, irregular, with not very deep cracks; with plumbeus grey upper surface and white medulla naked in the cracks. Soralia 0.3-0.5(-1) mm across, rounded, stipitate, usually at the edges of areoles, often aggregated in irregular groups 1-1.5(-2) mm across; soredious mass bluish or becoming whitish when without soredia. Soredia powdery, bluish, to 20 [micro]m diam. Hypothallus bluish black, to 5-7 mm wide in the peripheral zone sometimes also seen between areoles in places, at the edges in contact with other crustose lichens black line often present. Thallus in section to 150 [micro]m thick, cortical layer to 30-35 [micro]m thick, paraplectenchymatous, cell lumina rounded to 5 [micro]m diam., algal layer to 70-80 [micro]m thick....
