Holly Speckle - Trochila ilicina
This fungus forms a distinct, fine (<1mm diameter) dark speckling on dead holly leaves. It occurs on the upper side of the leaf only. The speckles (spore-producing structures) are first closed, and then open by a lid to expose the olive spore-mass, and finally appear as dry black, shiny depressions in the leaf, with a slightly raised lip.
