These tiny lichens are known as British Soldiers because of their bright red caps resembling red coats of colonial times. They are stunning and fascinating to read and learn about. They are a marriage between a fungus and an algae.
@laurentye They are cool. I shot them years earlier for 365 but didn't get a photo like this one. I posted one of them with a nickel too, so you could see how tiny they really are.
@janturnbull Thank you, Janet! Look for them on dead or rotting wood. I did post a pic of them with a nickel so you can get a better idea of their size.
