Lettau ex Vezda, Folia Geobot. Phytotaxon., 1: 312, 1966. Basionym: Gyalecta lecideopsis A. Massal. - Miscell. Lichenol.: 39, 1856.

Synonyms: Gyalecta hyalina Hepp; Gyalecta stigmatoides (Nyl.) Boistel; Gyalidea albocrenata (Arnold) Lettau; Lecidea stigmatoides Nyl.

Distribution: N - Ven (Lazzarin 2000b), TAA (Nascimbene & al. 2022), Piem (Isocrono & al. 2004).

Description: Thallus crustose, endosubstratic or thinly episubstratic, often inconspicuous and poorly evident, smooth or finely granulose, grey-white to yellowish grey. Apothecia 0.2-0,6 mm across, with a concave, dark reddish brown, dark brown to black disc and a smooth, crenulate or radially split, mostly black to brown proper margin (often turning pure white in dry sites). Proper exciple 50-60 µm wide laterally, dark olive-brown in outer part, colourless or paler within; epithecium brown-green; hymenium brown-green in upper part, colourless in lower part, 100-130 µm high; paraphyses mostly simple, to 1 µm thick, not swollen at apex; hypothecium colourless or pale yellowish brown. Asci 6-8-spored, thin-walled, apically thickened, with a small ocular chamber. Ascospores muriform, hyaline, ovoid to broadly ellipsoid, (17-)22-30(-35) x (10-)12-15 µm, without a distinct perispore. Photobiont chlorococcoid, Cystococcus/Leptosira-like. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a northern-montane species found on limestone, dolomite, calciferous schists, on porous, damp faces; easily overlooked, but certainly rare.
