It's marshland here (Elbmarsch) - so I find that lichen growing nearly on any surface. I think it's because the conditions for the alga to generate is much better due to the air being rich of humidity and minerals (saltwater air conditions)
Yes, that is also a funny thing, Lars. At the coast I think it appears on top of rocks, doesnt'it? But here, quite far from the sea, I always find it on tree barks!!
Common distribution hasn't much to do with beauty, I think, Scott :)
@arlanda: Yes, I assumed that actually - I thought that it might be regional differences. While your's is from a refion with definetely more sunlight (which algae don't like that much indeed), mine is from the coastal and more cloudy and humid region.
Thanks S Frazier, I agree with you it is very common and still I cannot resist to make pictures of it now and then.
Yeah Lars, that intrigues me a little. Yours is much greener. In Alan Silverside's Lichen Pages (http://www.lichens.lastdragon.org/Xantho......) it says that it is grey in shade and somewhere else I read that the yellow color is in part pigments to filter light and in that way protect the algae.
Was yours very much in the shade?
Now that is a particularly beautiful lichen, even if it is common!
very nice and colorful bright specimen, arlanda
Yes, if you look at lichens in detail, they are amazing nature wonders
This is new to me and amazing!
