WOOD DECAY.
Tree ID: eucalyptus tree
Observations: Fungus was located on bare soil, most likely infected near my tree roots. Closest tree was a eucalyptus tree, located roughly 6 feet away. Tree did not show visible signs of fungus. Only one sporophore was found (on ground). Tree leaves on one side looked more yellow than the other side. No deadwood shown on trunk.
DSI score: 2

Growing on Schinus molle.
Looked like it was pretty old but that may just be its color
Tree looked like it had been heavily pruned.
