Is this isidiate? I’m thinking maybe Imshaugia aleurites. What are the ID characteristics? Should be pale underneath; flat tiny lobes (and shiny where not tarnished by that algal film growing on it); tiny cylindrical isidia scattered evenly all over; K+ yellow cortex, K- C- KC- medulla. And no dots or cracks on the surface.
