Taille/poids :
Variable, pouvant aller jusqu'à 15 cm de diamètre, formant parfois des colonies étendues.
Diagnose :
Thalle foliacé jaune-orangé pouvant être gris-bleuté lorsqu'il croît à l'ombre. Les lobes sont plats et appliqués au substrat, de largeur comprise entre 3 et 7 mm, leur marge pouvant être légèrement récurvée. Plus larges à l'apex, ils se recouvrent partiellement les-uns-les-autres et ont souvent un aspect drapé. Le centre de la rosette est parfois formé de petits thalles sub-squamuleux. La face inférieure est presque blanche et munie de rhizines simples et peu abondantes.
Les apothécies sont généralement nombreuses, leur diamètre peut atteindre 4 mm, le disque est de couleur orangée au centre et le rebord est jaune, il devient légèrement crénelé avec le temps. La surface du disque est d'abord concave puis devient presque plate à maturité.
Facilité d'identification : simple.
Espèces proches :
Se distingue de Xanthoria aureola (Ach.) Erichsen par les lobes du thalle plus larges (entre 1,5 et 3 mm pour X. aureola) et l'abondance d'apothécies ainsi que par son thalle plus fin.
Se distingue de Xanthoria calcicola (Hepp) Arnold par la couleur plus claire de son thalle (orange foncé pour X. calcicola), l'absence de verrues ressemblant à des isidies et l'abondance d'apothécies.
Répartition générale.Cosmopolite, mais probablement introduit dans certaines parties du monde (ex : Australie).
Habitat et biologie.Espèce très commune croissant sur tout type de support riche en nutriments : arbres (pas de restriction concernant l'espèce) en bordure de route ou de culture, tuiles, murets, sur roche calcaire ou siliceuse, panneaux de signalisation, fil de fer barbelé, etc.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
This status is based on one or more of the following criteria:
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
This status must be assigned to a department in which the presence of the species is casual.
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
The map shows the global distribution of the species based on GBIF data (Global Biodiversity Information Facility).
