I am doing a bit of very unscientific experiments with Lichens. The top picture in the jar I am hoping is Evernia prunastri. I gathered it after the storms as it has been blown down from the trees as it appears to only grow on the upper branches. This I am fermenting in ammonia and as you can see I have a reddish color forming after a few days. The trees are covered with another lichen that is much finer and I am not sure if that is worth having a go with.
The second one I have not a clue what it is and if I will get any color. It grows in the woods here and is pretty prolific but judging by people's reactions it is not that common. It is large and has a green top and white underneath. I have it in a large bucket in the loo for people to pee into. Once it is full enough it can go out into the shed!! I am lucky at the moment as I have a cold and I have no sense of smell and so no idea what the house smells.
