Russula sanguinea (sanguinaria)

Debbie, mentioned to me about this collection as I’ve been busy
with the family.

In general Russula requires good notes for starters, and solid
microscopy in most cases for any meaningful identification to
emerge, but in this case I’m 99% sure that this is the most
ordinary species out there – Russula sanguinea with its pinkish
stem. These are abundant under Pinus and they fruit Summer-Fall-
Early Spring if sufficient moisture is present. I see them
fruiting right now in a well watered section of a local
park. This Russula is distinctly acrid and the cuticle does not
peel more than a few millimeters. I have seen some yellow
discoloration occasionally, a well as grayish discolorations too
when bruised, but these are not consistent. What is consistent is
the cream to pale yellow spore deposit. The spores have relatively short
warts (< .6 micron) that are isolated and almost never
form even a partial reticulum.

I have at least 20 more pictures of this spsecies that I will
need to add to my site:

Daniel, R. densifolia and R. dissimulans are many, many miles
away infragenerically — they’re a fundamentally different
species in the Section of the blackening Compactae that may turn
red or pinkish before going dark black/brown.

looks like it has yellowish gills, and maybe colored spores, too…

R. densifolia or R. dissimulans

Using Aurora’s key, one of the above. Only other possibility would be R. nigricans, and this would of necessity have to be a very young, very fresh, very immediate photograph, because R. nigricans stains/bruises red first, then black. Aurora’s key depends on taste: if acrid, then R. densifolia; if mild, R. dissimulans.

curious red staining on stem…does look like a russula.
