Description: Thallus crustose, episubstratic, ochraceous yellow to ochraceous orange, epruinose, smooth and subcontinuous or sometimes finely cracked, usually well-delimited, forming up to 3 cm wide patches. Apothecia frequent, 0.3-0.8(-1) mm across, persistently immersed in the thallus, with an initially flat, then sometimes convex, orange to brownish orange disc and a usually slightly paler, smooth, persistent margin. Epithecium orange, granular, K+ red; hymenium colourless, 50-80 μm high; paraphyses sparingly branched in upper part, the apical cells swollen, up to 4-6 μm wide; hypothecium colourless. hyaline, very variable, Ascospores 2-celled, polarilocular, hyaline, ellipsoid to broadly ellipsoid, 9-15 x 5-10 μm, the equatorial thickening (“septum”) 3-5 μm (1/4-1/2 of spore length). Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).Note: a poorly known calcicolous species described from Dalmatia. The epithet dalmatica seems to have priority within a difficult and still not fully understood complex of related species found on a wide variety of calcareous substrata in exposed, rather eutrophicated situations. The records reported from Italy refer to the species in a very broad sense; several of them could refer to other species, such as V. dolomiticola, V. epierodens, V. placidia, V. schaereri, V. velana.
