Corella brasiliensis

Corella brasiliensis is a species of basidiolichen in the family Hygrophoraceae. It was first described in 1890 by the Finnish scientist Edvard Vainio from specimens collected in the mountains of Brazil, where it was found growing on damp, soil-covered rocks. The species forms thin, olive-grey patches made up of small, overlapping scales that can merge into leaf-like structures, and it partners with blue-green bacteria to obtain nutrients. It is found in misty mountain forests from Costa Rica to Brazil, typically growing on shaded rocks and soil at the base of trees alongside mosses and other moisture-loving plants.
