Verdera Rock

Index card


Its green colour is due to a saxicolous lichen, i.e., lichen which grows on rocks. It shares this space with another orange lichen commonly known as Xantory.

When they die they turn grey. Note that at the foot of the holm oaks, just to the side of the rock, we find a pretty combination of moss, another type of lichen (in this case growing on the trunks) and the polypody fern.
