Ramalina farinacea is a lichen that hangs on the branches of the trees. It’s made of a greyish or greenish discoloured white, narrow, branched ribbons. When looking at these ribbons through a magnifying glass, a lot of small holes are seen on the edges. They contain the soredia, these are packs of fungal hyphae that surrounds algae cells, ready for vegetative dispersion.
Ramalina farinacea lives mainly on the branches of holm oak trees, in mature and humid enough evergreen oak forests.
