Taken outside my house, always wanted to do a picture with light trails. Next I want to do one over a motorway or something.

Comment: Pseudevernia furfuracea is a very common foliose-shrubby lichen in general and also in Trenta valley, particularly on higher elevations. It climbs up to the tree border elevations. It can be found on bark of deciduous trees as well as on conifers and sometimes also on rocks. Pictures show a young, still small specimen in damp state. Hence the thallus is almost white. Grown up specimens are darker - gray or brownish-gray, often densely covered with isidia and dark brown to black underneath. When old they sometimes become of bizarre shapes appearing completely different from these pictures. Apothecia are rare.
The species is very variable. Probably the best trait for determination is its growth. Terminal thallus strap-shaped lobes divide widely divergent and quite strictly dichotomously. All terminal lobes remain in a single plane and they are rather short. When dry the edges of the straps curl strongly inwards, sometimes completely covering the lower, black side of the straps. A very similarly looking habit has another common lichen - Evernia prunastri (L.) Ach.. But, its lobes are usually greenish, often net-veined above and white beneath (also when old).
Lichen was 3 to 4 cm tall growing on a relatively thin branch. 5% KOH reaction on thallus is yellow-green. Only one specimen has been found on this tree. Otherwise about 25 different lichen species have been spotted on it.

Between Heiligendamm and Kühlungsborn Ost, the "Molli" line runs close but never adjacent to the coast, and it is almost impossible to take photos of the train with the sea in the background. Only near "Steilküste", a stop opened in 1969 and serving a nearby camping and mobile-home ground, such a view is possible. 99 2324 with Bad Doberan-Kühlungsborn regional train; April 7, 2016.
2/1/13 - It was cold out today. I played tennis in the morning and found it hard to motivate myself to go out in the afternoon to take pictures. I hate to waste an opportunity to take pictures in daylight in the winter, I brought my camera with me when I went out to run an errand. I was taking pictures by a stream when I noticed the icicles by the edge of the stream. They were hanging down from the branches. I took some pictures until my fingers became too cold (I was wearing gloves).
