Rhizoplaca Chrysoleuca
''Rhizoplaca chrysoleuca'' (orange rim lichen, rock-posy lichen, rockbright) is a pale yellowish-green to gray-green umbilicate lichen, umbilicate foliose lichen, foiliose lichen in the Lecanoraceae (rim lichen) family.Lichen Flora of the Greater Sonoran Desert Region, Vol 1, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> It was first species description, described in 1791 by English botanist Sir James Edward Smith as ''Lichen chrysoleucus''; Friedrich Wilhelm Zopf transferred it to the genus ''Rhizoplaca'' in 1905.

The fruiting structures (apothecia have lightly pruinose, burnt-orange to tan discs rimmed, with a contrasting rim of pale greenish thallus-like tissue making them easy to identify. Apothecia are 0.8–2.5 mm diameter, and often numerous and crowded into each other. It grows in Eura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
