[Note Guidelines] Photographer's Note
One of the oldest known plants which has been around for many millions of years in virtually the same form. This unknown species was particularly bright yellow in colour.

In the natural environment, lichen "provides" the alga with water and minerals that the fungus absorbs from whatever the lichen is growing on, its substrate. As for the alga, it uses the minerals and water to make food for the fungus and itself. Algal and fungal components of some lichens have been cultured separately under laboratory conditions, but in the natural environment of a lichen, neither can grow and reproduce without a symbiotic partner. Indeed, although strains of cyanobacteria found in various cyanolichens are often closely related to one another, they differ from the most closely related free-living strains. The lichen association is a close symbiosis: It extends the ecological range of both partners and is obligatory for their growth and reproduction in natural environoments. Propagules ("diaspores") typically contain cells from both partners, although the fungal components of so-called "fringe species" rely instead on algal cells dispersed by the "core species".

Hi Murray,
Lovely capture.Colors,lighting,details,framing and composition are wonderful.
Thanks for posting.

Hi Murray,
These lichen are much more difficult to photograph than people imagine.
You've captured the colour beautifully here.
Nice composition.

Well seen and captured Murray,
I like those orange & yellow colors, some nice textures seen..
Great supporting notes on this also.
