coral spot fungi

This fungus, which causes die back of affected branches, was noticed on the coppiced lime. After death of the branch the fungus erupts into a mass of 1-4mm pustules of fungus, forming the sexual stage of its apparently complex life cycle.

This is the same lime stool which was sporting the velvet shank earlier in the year, although velvet shank affected the rotting stump whilst the coral spot was on a coppice branch, but not a healthy one. Coral spot affects broadleaves, particularly beech but is not uncommon on lime as here. As it is only weakly parasitic, the branch had probably had it anyway.
