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

in Arup & al., Nord. J. Bot., 31: 45, 2013. Basionym: Caloplaca limonia Nimis & Poelt in Nimis & al. - Bull. Soc. linn. Provence, 45: 252, 1994.
Synonyms: Caloplaca citrina auct. ital. p.p.
Description: Thallus crustose, episubstratic, pale yellow to yellowish green, sometimes weakly whitish-pruinose, often >200 µm thick, forming a more or less continuous to areolate-granulose, up to 10 cm wide crust. Areoles flattened, contiguous, 0.2-2.5 mm wide, densely covered in diffuse, 40-80(-140) µm thick, laminal blastidia and true soralia produced from cracked blastidia, or after the blastidia have eroded. Upper cortex paraplectenchymatous, evident only in young squamules; medulla white, rather thick. Apothecia rather frequent, zeorine, at first immersed, then sessile and constricted at base, with a yellow to yellow-brown, concave to flat disc, a yellow proper margin, and a thick, yellow, sorediate-blastidiate, finally sometimes excluded thalline margin. Proper exciple of more or less radially to irregularly arranged, strongly swollen hyphae that neither give rise to a recognizable paraplectenchymatous structure, nor to a true cortex; epithecium yellowish, K+ purple-red; hymenium colourless, c. 100 µm high; paraphyses loose, c. 1.5 µm thick, the last 2-3 cells larger, the apical cell c. 8 µm wide, more or less spherical, covered by an epipsamma; hypothecium colourless. Asci 8-spored, cylindrical-clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid to subglobose, 8-16 x 4-8 µm, the equatorial thickening (“septum”) 3-5.5 µm (c. 40 % of spore length). Pycnidia yellow-orange. Conidia (2.5-)3-4(-5.5) x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-, UV+ pale orange. Chemistry: thallus and apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
Growth form: Crustose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
