caloplaca ferruginea
The apothecia are characteristically a deep red colour with a flexuose or uneven rim. The thallus is white to grey in colour and may be immersed in the substrate. Usually found on the bark (neutral to basic) of mature trees or on twigs, including hawthorn and oak. When the apothecia are cut in section there is rarely any photobiont present (in the hymenium).

Emma, I think that to categorize lichens as "fungi" or as "other" in Project Noah actually depends on personal opinion or tastes.
I prefer "fungi" because it is
closer to lichens than "other" and they are "partially" fungi, but I agree with
LarsKorb that they are actually something else than "fungi".
Since in
Project Noah the categories are not complete and the main intention is to keep it simple I consider that anybody is entitled to chose "fungi" or "other"
to categorize lichens. I still, personally, prefer "fungi" since I do not have the lichen option.
Thanks Leuba, it is actually a very small one with mm sized apotecia. It is difficult to notice it. Although this spotting looks liki if it was on the trunk of a
tree, it is actually on a small twig
Thanks Emma - will do :)
BTW Leuba,it is better if you take Arlanda's advice on how to categorize Lichen.
very nice arlanda - it would have looked pretty sight on the tree !
I just changed the first picture
