Distribution: N - Frl (TSB 14671), Ven, TAA (Nascimbene & al. 2022), Lomb, Piem (Isocrono & al. 2004), VA (GDOR 186), Emil (Fariselli & al. 2020). C - Tosc, Sar (Nöske 2000).
Description: Thallus foliose, not umbilicate, multi-lobed, the lobes interconnected, with numerous holdfasts scattered over the lower surface, (3-) 5-15(-34) mm wide. Upper surface grey, usually pruinose; lower surface brown to dark brown, usually smooth but occasionally rugose or slightly reticulate. Upper cortex pseudoparenchymatous, of anticlinally arranged hyphae, often with a brown pigment near the surface, overlain by a thin epinecral layer of air-filled hyphae; medulla white, consisting of filamentous hyphae, I-. Perithecia common, slightly oblong, immersed in the thallus and scattered over almost the whole upper surface (appearing as black dots), without involucrellum. Exciple colourless except in the brown uppermost part; hamathecium or periphyses and periphysoids, interascal filaments absent; hymenial gel hemiamyloid. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid, (5.5-)9-13(-17) x (4-)5.5-7(-8.5) µm. Pycnidia common, black, immersed, multi-chambered. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on acid siliceous rocks, growing on periodically inundated surfaces. In the delimitation of this critical taxon I partly follow Roux & coll. (2014), who claim that the greatest majority of the records of D. decipiens from upland areas refer to this taxon. However, according to Heidmarsson (2017) this species, and D. intestiniforme, are just morphs of D. miniatum. As the molecular taxonomy of the D. miniatum-complex is not fully resolved, I prefer to maintain the taxon as distinct, at varietal level.
