Ganoderma applanatum
This ubiquitous polypore grows from wood, usually well decayed logs.  
Called the artist's fungus because the pore surface darkens when
scratched, lending itself to writing or drawing.  Large specimens of
Ganoderma applanatum can produce trillions of spores.
See Mushrooms Demystified, Arora,
1986, p.576.
