Observation 99193: Russula crustosa Peck

When: 2012-06-23

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were found in the Big Sandy Creek Unit.
Spores were in the range of 7.1-9.0 X 5.9-7.1 microns, moderately warted but no significant reticulations.
Taste was mild.
While the caps are fairly distinctive, I’m a little unsure of the ID because while none of the descriptions of this species really mentions a pinkish element, yet, the photos on Mushroom Expert and other places seem to show a similar color pattern, i.e., what looks pinkish to my eye.(?)

Hi Ron,
this is a close relative of Russula crustosa, which I provisionally called R.pallidocrustosa (it should be published next year). Strange as it may seem, this southern species is genetically closer to green species such as R.virescens and R.subgraminicolor than it is to R.crustosa itself. In David’s frontyard, R.pallidocrustosa and R.crustosa grow next to one another.
