Ganoderma australe. Earlier named G. applanatum but DNS shows mainly G. australe here. Quite widespread and common. Grows on logs and stumps, and on some living trees as a parasite, causing heart-rot. Thick shelves or brackets to 500 mm wide, 40-100 mm thick, growing to overlapping layers, colour zones dark brown to black on top. Underneath is a layer of whitish fine pores which marks brown when scratched or pressed, all becoming brown with age. The brackets often engulf grass and twigs as they grow, and the dark brown spore powder dusts nearby objects. Myrtle Loop Walk, The Beeches, Marysville, 2008.
