Nice lichens, injica! They are very difficult to identify. I am not really sure that the dark one is Collema sp., most of collemas appear of rocks, except C. furfuraceum, that is black, and C. fasciculare, very different. I am not saying that you are wrong, it is difficult to decide from the picture, but check Melanelixia glabratula, it could fit with yours. The grey ones I think are Parmelia sulcata (the big one) and the small grey one looks like Physcia tenella or Physcia ascendens. Good luck!!

Ok, I'll do my research about them, I wasn't sure about Collema too but it was really close to the lake so I thought it might be... Tnx :)
