Colourful lichen
Found on an old roof, Cape Town, South Africa.
Lichens are complex plants made up of algae and fungi growing in symbiotic association on a solid surface. In the photo you can see them as the clusters of yellow-green and light grey shapes.
Thank you Sonja for pointing out to me the spelling mistake in the original caption, which must have been very puzzling to German speaking viewers - " leichen" would translate to corpses!!
