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.[2] It grows on non-calcareous rock, wood, and bark.[2]
The taxon Candelariella vitellina var. mendozae, proposed by Finnish lichenologist Veli Räsänen in 1941,[3] was promoted to distinct species status, Placomaronea mendozae, in 2004.[4]
Description
Candelariella vitellina often has tiny lobate areoles in the shape of lion claws.[2] The areoles may be flat or convex.[2] Its sexual reproductive 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.[2] The results of lichen spot tests are K+ reddish, KC−, and C−.[2] It produces calycin, pulvinic acid, pulvinic dilactone and vulpinic acid as secondary metabolites.[2]
Candelariella vitellina looks like a miniature version of C. rosulans.[2] It can be distinguished by C. vitanela having a visible exciple (the rim around the apothecia disc), which C. rosulans does not have.[2] It is usually much larger and thicker than the similar C. lutella.[2]
