But around S.C. I have found most with Redwood, less common with oak.
Up north they seem more centered around Pine.

Can’t pinpiont an exact host with these. It seem the bigger the mix the more likely they will show up. The largest fruiting I have noticed was with a good amount of Doudlas Fir present (over a dozen or so).

I was a little surprised.

I thought it was a little surprising to see these there. I’ve only ever found these in the northern coast, not in the bay area. But I see there are other obs. here from the Santa Cruz area, so it isn’t that surprising. Increases the range for these for me at least.

There was quite a bit

in Nisene Marks in late November, but that was the only substantial fruiting that I saw.

Nice find.

These seemed to be very common in this area this year.:)
