Not sure, maybe Gray Pine?

I don’t think I knew much about tree ID back when I found this. I tried digging up pictures to see if there were any Suillus photos taken on this hunt but couldn’t find any. I don’t remember seeing Monterey Pines at this park, and I have read that Gray Pines grow there (I’m sure it’s not the only species though). I will probably head up there this week and I will definitely take some notes this time!

I know that it is published that they the western Chroogomphus can ‘apparently’ look identical, but I actually don’t agree with that. The olive tones on the young cap and (sometimes subtly) different cap color even in age tells the Suillus fuscotomentosus associate apart from the Suillus pungens associate pretty well in my experience. Given the colors on this one, I’d bet that it was with S. fuscotomentosus and something other than Monterey Pine (probably Knobcone?).

Randy, can you remember which Suillus (if any) was fruiting, or what pine species was around?
