Observation 143629: Russula cyanoxantha (Schaeff.) Fr.
When: 2013-07-25
No herbarium specimen

Notes: This species has most of the features of R. variata, except there was no bitter taste; the pilepellis peels easily about halfway to the margin; applying KOH to the cuticule causes the pigments to bleach orangish. Also the key feature for this species is the gills fork close to the margin only. Unfortunately this is not well illustrated in my photo of the gills, but was present in my notes. I should have checked my photos before I delete4d them from my card.

Ah, I see your notes now. In the picture it appears as if there are furcations towards the margin, but that may be an artifact of the blurriness. There is another species in this group that has a lilac color pileus and and furcations at the base, which may be undescribed. I haven’t been able to find any specimens of R. cyanoxantha in Tennessee, but if it occurs in the U.S. then Pennsylvania is not a bad bet. I hope you are able to recollect!

I just voted doubt it concerning your prposal for R. variata, due to the fact that the gills only forked near the margin and R variata gills are forked often from the stipe to midpoint to the margin. I realize that my photos do not show this feature, but my notes when I collected did. I propose to find this again and illustrate the gills in a better manner.
