I remember when I first saw this in our Cemetery where we walk the Furlong dog. I thought someone had desecrated the graves by chucking white paint on them. I remember feeling very offended – until I investigated.
At this time of year, this lichen is most noticeable. It grows on old grave stones and stone walls that are in the light. I can’t say “sunshine” because we seldom get it here. But it’s not on stones under trees. It’s very strange and in-your-face-white. And it’s everywhere.
Lichens are truly interesting creatures – they are not plants – but symbiotic organisms. They are used as a marker for air-pollution, of which there is very little here, where we live. They have anti-biotic properties and they are totally fascinating in every way.
Here are our gravestones snapped on our walk today.
