Cladonia anaemica

About

Cladonia anaemica is a species of fruticose lichen in the family Cladoniaceae. It has a persistent base of small, pale greenish scales marked with distinctive red patches at their tips, and produces slender upright stalks (podetia). The species is locally common on bare sands, thin soil, and quartzitic outcrops in eastern Brazil, and has also been recorded from Uruguay. It was first described by William Nylander in 1860 as an infraspecific taxon within Cladonia sanguinea, and was raised to species rank by Teuvo Ahti in 2000.
