Herere some of the British lichens I have photographed. Most species do not have a common name but a few do and I have included a few of those.
There are at least seven species of lichen in this photo.
Woodlands and sea shores are the best places to spot lichens.
Sometimes you can see the fruiting bodies in them.
Cap Lichen (Caloplaca heppiana)
Reindeer Moss (Cladonia species) N.B. not a moss but a lichen but the green stuff below it is a moss.
Trumpet Lichen (Cladonia species)
Matchstick Lichen (Cladonia floerkeana)
Pixie Cups (Cladonia pyxidata)
Oakmoss (Evernia prunastri)
Elegant Script Lichen (Graphis elegans)
Disc Lichen (Tremolecia atrata syn. Lecidea dicksonii)
Dog Lichen (Peltigera species)
Antler Lichen (Pseudoevernia furfuracea)
Old Man's Beard (Usnea species)
Over 600 substances have been extracted from lichens which help them to survive in marginal environments and ward off attacks by bacteria, other fungi and grazing herbivores. These substances include pigments used in dyeing, toxins, air pollution monitors, perfumes, food and antibiotics used in medicines.
(I am not a lichenologist so please do not rely on my identifications - there are dozens of similar species and many are very hard to identify.)
Scheduled to come on at midnight NZST. We shall see if Blogger obliges! It's been changing my scheduled posts back to drafts a lot of the time.
