POWDER-EDGED RUFFLE LICHEN
Powder-edged ruffle lichen (Parmotrema stuppeum) growing on pine bark. A lichen is a symbiosis between a fungus and an alga. The fungus provides the structural support for the lichen partnership, while the alga provides food by photosynthesis. Photographed in Spain. (KEYSTONE/SCIENCE PHOTO LIBRARY/DIRK WIERSMA)
