growing on headstone in Victorian cemetery
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
but identification of these requires at least a very close examination with a lens, or a high-resolution extreme close-up.
Knowing the type of rock, or in this case, headstone, on which the lichen is growing can be helpful in lichen identification. Verrucaria baldensis is found on limestone, for example. Have you followed the Group link on the Home page to Fungi and Lichens? This gives several other useful lichen links, in addition to Alan's www.lichens.lastdragon.org
