Phellinus sp. are a world-wide genus of wood-rotting fungi that grows on stumps and logs, as well as being parasitic on living trees, eventually killing them by heart-rot (Latin: phellinus ; cork). Phellinus grow as flat sheets of pores, as brackets with pores underneath, or often form large hoof-shaped dense, woody bodies, as shown in these images; the upper colour is dark brown to black, often with cracks. The species of these images are not known, but the form is characteristic, especially with the underneath fertile surface consisting of very fine pores. Devilbend Reservoir, Mornington Peninsula, 2008.
