}}Candelariella vitellina is a common and widespread green-yellow to orange-yellow crustose areolate lichen that grows on rock, wood, and bark, all over the world.[1] It grows on non-calcareous rock, wood, and bark.[1] It often has tiny lobate areoles in the shape of lion claws.[1] The areoles may be flat or convex.[1] Its sexual reproduction structures (apothecia) are a 0.35–1.0 mm-wide disc, darker yellow than the thallus, rimmed with thallus-like tissue lecanorine, flat but becoming convex with age.[1] Lichen spot tests are K+ reddish, KC-, and C-.[1] It produces calycin, pulvinic acid, pulvinic dilactone and vulpinic acid as secondary metabolites.[1] In California, it prefers growing on granite, but can also be found on wood (rarely on bark) and other kinds of rock.[2]{{rp|251}} Candelariella vitellina looks like a miniature version of C. rosulans.[1] It can be distinguished by C. vitanela having a visible exciple (the rim around the apothecia disc), which C. rosulans does not have.[1] It is usually much larger and thicker than the similar C. lutella.[1]References1. ^1 2 3 4 5 6 7 8 9 Lichen Flora of the Greater Sonoran Desert Region.
