The Living Forest (352) : Yellow Scale
Yellow scale is a lichen that grows in all continents on earth with exception of the polar regions.
Lichens form a nice colourful accent in the winter forest.
Just like fungi, lichens too are an interesting and fascinating aspect of nature with 25.000 species having been described and identified worldwide.
A lichen is a composite organism consisting of a fungus and a (green) alga and grows as a single individual mostly on trees (but also on bare rocks, man made walls and concrete gravestones).
In ancient Egypt, lichens were used as packing material for……. mummies !
