Xanthoria resendei Poelt & Tav.
Portug. Acta Biol., B, 9, 3-4: 302, 1968.
Synonyms: Martinjahnsia resendei (Poelt & Tav.) S.Y. Kondr., Fedorenko, S. Stenroos, Kärnefelt, Elix, Hur & A. Thell; Xanthoria subelegans sensu Tav. & Poelt
Distribution: C - Tosc (Senese & Critelli 2000, Loppi & al. 2004c). S - Si (Ottonello & Romano 1997, Ottonello & al. 2011).
Description: Thallus foliose, closely attached, bright orange-yellow to deep orange, forming 3-8 cm wide, more or less regular rosettes. Lobes radiating, 0.4-0.6 mm wide, contiguous to separate, bifurcate or sparingly dichotomously branched, markedly convex and worm-like, stiff, the surface granulose to verrucose, with scattered paler maculae. Cortex paraplectenchymatous; medulla white, with 17-35 µm wide chondroid strands of densely compacted hyphae. Apothecia lecanorine/zeorine, sessile, 1-1.5(-2) mm across, with an orange, flat disc, and a smooth to crenulate, usually paler, often finally excluded margin. Epithecium inspersed with orange granules reacting K+ red; hymenium colourless, 40-60 µm high; paraphyses simple or bifurcate, swollen at tips; hypothecium colourless, underlain by a more or less continuous algal layer. Asci 8-spored, 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, broadly ellipsoid, 8-12 x 6-8 µm, the equatorial thickening (“septum”) 3-4.5 µm. Pycnidia immersed into orange warts, most frequent in central parts of thallus. Conidia ellipsoid-bacilliform, 2-3 x 0.8-1 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ dark red, C-, KC-, P-, UV+ intensely orange-red. Chemistry: thallus and apothecia with different anthraquinones (physcion, fallacinal, fallacinol). Note: an apparently western Mediterranean (Macaronesia, NW Africa, Iberian Peninsula to Italy), strictly coastal silicicolous species, most frequent on steeply inclined surfaces of basic siliceous rocks in exposed situations.
