A couple of conjoined light-brown/beige cushions each about 4 cm across, 1 cm high growing on snapped end of a detached branch - probably of a Prunus. Areas where you can see pores where tubes are growing almost parallel to surface. 4-5 pores/mm, 100-200 microns in diameter with furry edges, tubes about 2 mm long, in layers, lower tubes white inside and at different angle to higher ones. Pored surface bruised darker brown when I pressed it with my thumb. White mycelium visible where fungus met the cut end of the branch, at first I mistook it for spider's web!. Firm but cutable with sharp knife. Stained black with Potassium hydroxide. Firmly attached to substrate but a slice could be prised off when cut. Flesh rich brown colour. No obvious smell. Under the microscope I could see fibrous strands but no spores.
