Exidia recisa ---- one of the jelly-fungi

 Exidia recisa, Amber Jelly.

This was seen today in Pembrey Country Park.  It is a species found during the winter months, on Willows but you need to look at small branches at head-height.  Although records suggest it is uncommon I think it might be found everywhere, particularly after some days of damp weather, on small branches of willow .  During dry weather it dries to form an inconspicuous brown crust which revives after rain. 

This was taken of a willow branch in Pembrey Forest in January 2010 where it is present on many shrubs.  After a sudden heavy frost the fb's do not dry out but become frozen and covered in ice crystals as these were in Nov 2010.
