Thallus: foliose, appressed to agglutinated up to the lobe tips, 2-8 cm in diam., dichotomously pinnately or subpinnately lobate; lobes: radiating, confluent, flat or convex but sometimes concave near apex, 0.5-1 mm wide, not flabellate towards the lobe tips; upper surface: gray, bluish gray or almost white, shiny, not (or very faintly) pruinose, sorediate; soredia: farinose, in laminal, globose soralia; pseudocyphellae: present, but not distinct, marginal, rarely also laminal, usually restricted to the peripheral parts of the lobes, rarely reticulately confluent; medulla: white, the lowest part seldom orange, if so, only at the lobe tips; lower surface: black in center, paler towards lobe tips, erhizinate; Apothecia: very rarely present, laminal on thallus, 0.7-1.3 mm wide; disc: jet-black, not pruinose; ascospores: brown, 1-septate, narrowly ellipsoid, 14-18 x 5.5-7.5 µm; Pycnidia: immersed in warts; conidia: bacilliform or fusiform, 3-4 x 0.9-1.1 µm; Spot tests: upper cortex K+ yellow, C-, KC-, P+ yellow; medulla upper and lower part K-, C-, KC-, P-; Secondary metabolites: upper cortex with atranorin; medulla with divaricatic acid and few terpenes in low concentration.; Substrate and ecology: on bark (predominantly on Cocos) and wood, along or near beaches; World distribution: in all tropical regions of both hemispheres; Sonoran distribution: especially in thorn forests and deciduous forests of Baja California Sur and Sinaloa.; Notes: Only with some hesitation are the Sonoran specimens identified as Dirinaria picta. It is most likely that this common species does occur in the Sonoran region, but we have seen no typical material in the many collections from there studied for this paper.

Recolector del tipo:
Talo folioso de 2 a 8 cm de diámetro, está unido al sustrato; tiene lóbulos de planos a convexos, pero a veces cóncavos cerca de las extremidades de los lóbulos, miden de 0,5 a 1,0 mm de ancho. La superficie superior es gris, o de gris azulada a casi blanca, brillante, sin gránulos de oxalato de calcio (pruina); presenta IMAGEDB.GET_BFILE_IMAGE?p_imageId=39684&p_imageResolutionId=2">soralias">http://attila.inbio.ac.cr:7777/pls/portal30IMAGEDB.GET_BFILE_IMAGE?p_imageId=39684&p_imageResolutionId=2">soralias farinosas, mientras que los isidios y las máculas están ausentes. Médula blanca, la parte más baja raramente es anaranjada, o sino, solamente se presenta en las extremidades de los lóbulos. Superficie inferior negra en el centro y más pálida hacia las extremidades de los lóbulos y sin rizinas. Los apotecios en algunas ocasiones están presentes, éstos miden de 0,7 a 1,3 mm de diámetro; el disco es de color negro y sin gránulos de oxalato de calcio (pruina).
Crece sobre la corteza de árboles, a veces sobre rocas y madera (postes de cerca); en vegetación húmeda a seca de elevaciones bajas a medias; prefiere micrositios abiertos a semiabiertos (orillas de camino, áreas de pastoreo, plantaciones, orillas de playas, bosques secundarios, bosques secos).
