Collection location: Samuel P. Taylor State Park, Marin Co., California, USA [Click for map]
These were growing on a fallen tree over a creek.
The tree bark looks unusual for this area which is primarily Bay Laurel, Live Oak and some Doug fir.
The white pores did stain brown when scratched and were ~ 3-4 per mm. The pores eventually turn a dark gray in age as seem in the photos.
Beneath the white pores was a layer of dark reddish-brown tubes up to 2 cm deep.
I could not get a spore print but by chopping up some tubes and washing with KOH, a few mature spores were observed. They were double-walled with hairs in between and were ~ 11-13 X 7.5-8.5 microns.
They were very Ganoderma-like and similar in size to the G. brownii/annularis.
The near resupinate growth pattern does not appear to match any Ganoderma I could find.
