Wonderful world of lichens

WE see them almost everywhere we look, every day, but don’t give them a second glance.

They are part of natural life around us, so much so that we just take them completely for granted.

They thrive on walls, trees, gateposts, roofs, rocks and stones and are often best demonstrated on headstones which have taken the brunt of the elements over many years in graveyards. Anything in the outdoors that appears old has them in abundance. In fact, they make things look old.
