Description: Thallus fruticose, tufted, often forming up to 3(-4) cm high, loose cushions, attached by a basal holdfast, bright orange (yellow to grey in shade-forms). Branches at first stellate-radiating and c. 0.5 mm wide, but soon becoming erect, of variable width (usually 1-2.5 mm), rigid, slightly dorsiventral, usually with ciliate tips, smooth or weakly wrinkled especially on the paler lower surface, with laminal and terminal, 0.3-1 mm long cilia. Upper cortex of longitudinally arranged hyphae; medulla interrupted by cortical strands with algae in scattered groups, 40-130 µm thick; lower cortex prosoplectenchymatous. Apothecia almost always present, mostly terminal to subterminal, lecanorine, up to 8 mm across, orange to orange-red, the margin with numerous, radiating, 0.5-1.5 mm long cilia. Epithecium orange, K+ red; hymenium and hypothecium colourless. Asci 8-spored, oblong to clavate, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, (10-)12-17 x 5-8 µm, the equatorial thickening (“septum”) 4.5-7 µm. Pycnidia immersed to slightly projecting in 0.1-0.15 mm wide, darker orange warts. Conidia narrowly ellipsoid, 3.5-4.5 x 1.5-2 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-, UV+ intensely orange-red. Chemistry: anthraquinones such as parietin (major), fallacinal, teloschistin, and parietinic acid (all minor), and emodin and erythroglaucin (both minor).
Note: typical of situations with a dry climate with frequent spells of fog, this species grows on twigs of shrubs and isolated trees in open habitats. It was much more common in the past, and presently it is extinct in many regions (especially in Northern Italy), but there is some indication that in some parts of the country, especially in the Tyrrhenian ecorgion, the species is slowly recovering. The name is usually spelled chrysophthalmus but chrysophthalmos in Greek is a noun, not an adjective (Arcadia 2016). It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
