Caloplaca livida (Hepp) Jatta
Syll. Lich. Ital.: 247, 1900. Basionym: Placodium lividum Hepp - Flecht. Eur.: nr. 403, 1857.
Synonyms: Callopisma lividum (Hepp) Körb.; Caloplaca convexa (Schaer.) Zahlbr.
Distribution: N - TAA, Lomb, Piem (Isocrono & al. 2004).
Description: Thallus crustose, pale grey to whitish, very thin, continuous, often inconspicuous. Apothecia frequent, rounded, sessile, strongly constricted at base, 0.3-0.5(-0.8) mm across, with an ochraceous orange to brownish orange, at first flat, then strongly convex disc, and a thin, concolorous, often finally excluded proper margin. Epithecium orange-brown, K+ red; hymenium colourless 50-60(-90) μm high; hypothecium colourless. Asci 8-spored, clavate, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, narrowly ellipsoid, (13-)14-16(-18) x (5-)6-7(-8) μm, the equatorial thickening (“septum”) 2.5-3 μm, c. 1/4 of spore length. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red. Chemistry: thallus without lichen substances; apothecia with unidentified anthraquinones.Note: an arctic-alpine species found on plant debris and bryophytes overgrowing acid siliceous rocks, with optimum near and above treeline. The species belongs to Bryoplaca and the new combination will be published soon (Arup in litt.).
