>>926629Yo. North Bay forager here. What part of the bay area are you in?
I'm in Santa Rosa and I'm still finding shit. You can usually count on there being mushrooms up somewhere from the first major rain of the fall season all the way though mid spring. Understand that mushrooms fruit in flushes. A variety of environmental conditions will determine when a species fruits-- and different species fruit in different conditions. Everything has its peak season, but you can usually find a given species' before and after it peak. Understanding and exploiting topography / microclimate will help you find stuff all year round: you can find chanterelles in august along the coast where there's abundant fog drip.
Lately I've been fining candy caps (lots!), chanterelles (C. californicus and subalbidus), pigs ears, black trumpets, and Hericium. Your best bet this time of year is hunting under coast live oak or tanoak. I don't have any mature doug fir in my area, but it's probably good right now too; I made a trip to point reyes a couple weeks ago and it was poppin'.
This storm we're having should bring lots more out in the coming weeks. Black trumpets especially. Good luck!
