Has several distinctive features, the most promising is the pliable gills that don’t break like many other Russula species. Rub your fingers across the gills and if they remain intact, you likely have R. cyanoxantha. The next would be iron salts on the stipe.

This one should be easy

I have found it from the button stage to maturity and few times now, it should be fairly recognizable to now, it’s the R. Parvovirescens vs R. Cyanoxantha that I can struggle with even when using the microscope sometimes.

They’re very distinctive and once you come across one, you’ll never have a problem identifying them (except possible confusion with R. parvovirescens).

This is my first time seeing this one in my area. I thought it was an old R. Cyanoxantha at first, then realized it was different. I will taste it next time, usually they are so buggy I don’t even try but I’m curious about this one.
