Ramalina sorediantha
ramalina, Ramalina
This species is not to be confused with R. sorediosa, which, in spite of its similar name, differs significantly in its thallus morphology. Ramalina sorediantha has ±flattened, in part canaliculate lobes, whereas R. sorediosa resembles a small Usnea with very thin, almost entirely terete branches that are never canaliculate. Several specimens in CDS are currently included in R. sorediantha s. lat. with some reservation. These specimens have lobes that are less obviously canaliculate than R. sorediantha s. str. They are therefore similar to R. pacifica, a species previously not reported from South America. More material should be examined to clarify the identity of these specimens.
