Normandina chlorococca (Leight.) Orange

Lichenologist, 54: 374, 2022. Basionym: Verrucaria chlorococca Leight. - The Lichen Flora of Great Britain and Ireland, ed. 3: 484, 1879
Synonyms: Arthopyrenia chlorococca (Leight.) A.L. Sm.; Lauderlindsaya chlorococca (Leight.) Diederich & Sérus.; Normandina acroglypta auct. non (Norman) Aptroot; Sphaerulina chlorococca (Leight.) R. Sant.; Thelidium chlorococcum (Leight.) Keissl.; Thelidium sorbinum (Nyl.) Hulting
Distribution: N - Frl (TSB 26042), Ven (Thor & Nascimbene 2007).
Description: Thallus crustose, episubstratic, dull grey-green, at the beginning smooth or consisting of small, convex, goniocyst-like granules which rapidly become irregular in shape and coalesce, forming an uneven crust, or often reduced to a collar surrounding each perithecium, sometimes (in young specimens) formed by subeffigurate units, the terminal lobes 25-60 μm wide; soralia scattered, diffuse, concolorous with thallus; soredia 20-40 μm across, often with projecting, colourless hyphae. Perithecia black, 0.2-0.4 mm across, one-quarter to three-quarters immersed in thallus, the ostiolar area not or only slightly depressed. Exciple reddish brown but irregularly pigmented; involucrellum absent. Hamathecium of periphyses, interascal filaments absent; hymenial gel I+ red (I+ yellowish or blue at low concentrations of I), K/I+ blue. Asci 8-spored, clavate, the wall thickened in upper part, K/I-. Ascospores 5-8-septate, hyaline, ellipsoid-fusiform, (22.5-)27.5-36(-39.5) x (6-)6.5-8(-9) μm. Photobiont chlorococcoid. Spot tests: Thallus K-, C-, KC-, P-, UV-. Chemistry: zeorin (traces).
Note: a mild-temperate lichen, most often found on mossy, subacid to base-rich bark; known from Veneto and Friuli, to be looked for further in Italy. Orange (2022) described N. acroglypta as occurring over rock and N. chlorococca over bark, but all three Norwegian specimens of N. acroglypta included in his phylogeny occurred over bark (Svensson & al. 2024), so that the difference in substrate does not appear to be diagnostic.
Growth form: Crustose
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
