In autumn 2015, the first record of it in Wales was made further up the Cynon Valley, though not by me and since then I have been keeping my eye open for it.
Strangely; straight after the first discovery in 2015, I went on holiday to Dorset and accidentally found it on Winfrith Heath nature reserve. It isn't quite so rare down there, but it was a first for the reserve.
The position of the first site is being kept secret, as these foliose lichens on trees are very vulnerable to accidental damage, so I will not divulge its location here. As far as I am aware, this is only the second record in Wales, though hopefully someone will put me right on that.
Sorry about the photo. The camera was on a tripod, but there was just enough breeze to gently move the tree as I tried to photograph it.
|Teloschistes chrysophthalmus, The whole lichen is only around 15mm across.|
|Xanthoria parietina. The middle two apothecia have black dots on them. Those|
are the pycnidia of a lichenocolous fungus; possibly Lichenoconium xanthoriae.
I took a specimen and will check it out.
