White spored? Ok then.

Ok, if white spored than that falls somewhere in the Griseinae group, which is consistent with the Oak habitat. But still, did you get a good spore deposit? They look so much like aeruginea… Any macrochemical info – how quickly did it react with Guaiac? Did you peel the cuticle? I will resist making species guesses until I have all critical information available. Do you have other pictures of these – they should be darker greenish in general. Any slides with spores, or the dried material, by any chance? This is not an easy group to decipher at all. Did the gills fork a lot – Russula variata is in that range too.

I don’t think so…

My understanding of R. aeruginea is that it is yellow spored, and these were white. There was no birch around, and I found these in several spots, always near oak (I think white oak), although in a stretch I think there might have white pine, perhaps 100 feet away? That might be a stretch… Certainly no birch.

This one looks like Rususla aeruginea. Did you see Birches near by? This is a peculiar Russula that grows with Betula, or in montane areas with Fir (Abies). I think I’ve beaten that species to death here:

There are other greenish Russulas in that group. All mild with rather limited spore ornamentation.

Just getting these things posted, and already need more info… I’ve got to get to work now, and I’ll post more later…
