How to identify Lumpy brackets (Trametes gibbosa) (courtesy of the First Nature website):
– found on most kinds of hardwood trees but most commonly on Beech (these were on Beech)
– the pale upper surface is often discoloured by green algae, particularly away from the edges
– the pores are slot-like, rather than round or oval as found on other whitish Trametes
I found this impressive array of Lumpy brackets on a huge fallen Beech in Cardiff’s Heath Park.
