Well this is a subject I do not know much about, Lichens,Thank goodness for google and books. This is another of the Common Yellow/Orange lichen (Xanthoria parietina, although this one is mainly greeny grey, it is seen here growing on a Twig of an Elderberry (Sambucus nigra) this joint in the branch is about 2cm across.The little orange cups are the fruiting bodies from which the spores will be released. the elder is growing in a wild area at the bottom of my mums garden they are part of a wooded area containing also hawthorn , and ashtree's all native to this part of the UK.
The information below was selected in part from this excelent site .hainault forest Scotlandand from here where there is more information about them than you ever thought posible .
A lichen is an association between a fungus and either an alga or cyanobacterium, both of which contribute the photosynthetic pigment chlorophyll, necessary for photosynthesis - being the conversion of carbon dioxide and water to complex carbohydrates in the presence of sunlight. What the benefits of such partnerships is little understood and is described as mutualistic.
Lichens are very sensitive to air pollutants such as sulphur dioxide, so for many years they became very scarce, now with various clean air laws being past they are making a come back both in number of species and number of colonies.
Taken on the afternoon after Englands 1st significant snow fall for a while, the snow reflected light making for a bright clean bright image.I was too busy to get the ones with snow on them and it had warmed up enough to melt it off the branches.

Your note brings me in a different nature world, where appearance is discreet and living is fragile. Your photo is beautiful, very detailed, with superb colors and brightness. I like your framing, including the sign of a winter bright sunny day. Thanks for posting, Bob.

So that is what it's called ;-)) We have quite a lot of this type of lichen (or very similar) growing on the older branches of various bushes around here, only I've never seen it as detailed as this. The colours are vivid and true to life. Upping the F-stop a bit might have been advisable to get all parts of the main body completely within DOF range.

I love this photo Robb. The texture and the colour and the shape all go together to make this feel like a sunny day at the seaside. Does that sound crazy to you? Hmmmmm
It almost has the look of an underwater coral shot. It has a nice cool feel to it.
Interesting notes too. Good post.

Your post makes us realise how little we know about Gods creations and how it is all intertwined to be what we call nature.
Very good image with interesting notes. Good job Rob TFS

I have never seen lichens like these, and your note is very good.

The sharpness and DOF is excellent and I like the composition.

Very well done and thanks for posting.

Thanks Robert, this posting is great. Lichen are everywhere (here) and it is so often overlooked. I was practising this week on some at home, and will think about posting one day. This shot show the beauty of the lichen. Notes very helpful too. TFS.
