This foliose form of lichen is on the majority of rough-surfaced rocks. They differ in colour and size but they are immensely abundant within the National Park Timanfaya.
Another example of foliose lichen in close-up.
As we know, the lichens are lively associations mainly between algae, which carry the chlorophyll and are able to photosynthesize, and filamentous fungi which are definitely dependent on ready-to-use food resources. Lichens are extremely widespread and found worldwide; present from the Arctic, to the equator and Antarctic. There is probably no place on Earth where fungi, algae and thus lichens don't occur. In a previous article, several examples of lichens, which were found during a journey to the North Cape, living in the Arctic tundra were illustrated.
Do you see little plants at the junction between lava grains of a few centimetres and lava rocks with their green and flat surfaces? So, there is, no doubt, visible life if you take the effort to find it.
And what about those cacti?
