Flavoplaca ora (Poelt & Nimis) Arup, Frödén & Søchting

in Arup & al., Nord. J. Bot., 31: 46, 2013. Basionym: Caloplaca ora Poelt & Nimis - in Nimis & Poelt, Studia Geobot., 7, suppl. 1: 70, 1987.
Synonyms:
Distribution: C - Tosc, Sar. S - Si (Nimis & al. 1994).
Description: hallus crustose, episubstratic, bright orange, areolate in central parts, more or less distinctly lobulate in marginal parts, forming irregular rosettes which are often confluent and cover large areas, without a distinct prothallus. Apothecia numerous, sparse or more often clustered, rounded or irregular, 0.2-0.8 mm across, with a more or less flat, deep orange disc, and a thin, usually somehow paler orange margin. Epithecium orange-brown, K+ red; hymenium colourless; paraphyses 1-1.5 µm thick, the apical cells weakly enlarged, 1-2(-2.5) μm thick; hypothecium colourless. Asci 8-spored. Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, (9-)10-12 x 4-6 μm, the septum 3-5 μm thick. 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 Mediterranean lichen found on siliceous, more rarely calcareous rocks near the sea, often associated with specimens identified as F. marina (see note on that species), apparently without transitional specimens. The species could prove to be a synonym of Flavoplaca maritima (B. de Lesd.) Arup, Frödén & Søchting.
