Lichen

[jennyb]

I saw this (http://www.wildaboutbritain.co.uk/ga...mage-8613.html) in the Gallery the other day and it seemed to be similar to something I found last autumn (see attached thumbnail). Is it the same? If not, does anyone have any idea what it is. I know nothing about lichen.

Jenny your lichen is Evernia prunastri

It may be coincidence but there seems to be a lot more lichen about now since leaded-petrol was banned .Is there a link?

That’s a good question nightshade And why are there always masses of lichen on church walls. Are they religious?

Thanks for confirming this, John.

This afternoon I found more lichen (see below). I thought that the first may also be Evernia prunastri, but possibly in an earlier stage? Am I right? It was growing on an oak tree. The second was growing on a twig (not sure what kind). Any idea what this is? Sorry, I know my photos aren't the best.

I am beginning to realise that trying to catalogue everything in my garden is a mammoth task. I had not even thought about lichens until now!

Jenny your first lichen is probably Parmelia sulcata (was it black underneath?) and your second one is Xanthoria parietina

Are theses WAB images Jenny? The reason I ask is that I don't really have the time or the expertise to ID other website images.

There are good sites on the web for lichen using Google

There probably is, Lichens are excellent bio-indicators, more species are likely to be found where the air quality is better.

After I have identified something, I look on WAB to see if there is already a good image in the Gallery. If not, I upload mine. Most of the images in the Gallery are far better quality than mine so I only try to fill in the gaps.

I am pretty good at identifying things like flowers and trees but I am new to fungi and even newer to lichen so I really don't know where to start with ID's. So many of them look so alike that I can go off in a completely wrong direction.

Please don't feel obliged to respond to any of my posts.
