Observation 15563: Russula Pers.

When: 2008-09-22

Collection location: Boone Co., Missouri, USA [Click for map]

Who: MOFunGuy (jrapp)

No specimen available

I’m working on the ID for this mushroom that I think is a Russula. It was found September 22, 2008 in a Central Missouri mixed hardwood area. The cap is pretty distinctive with a fawn, brown color which is cracked with lighter areas showing thru. The gills and stem are off-white or a very light tan. Russula ballouii is the closest I’ve come to ID’ing it (Phillips pgs. 126-7), but I haven’t found any description or image that shows the cracked brown color that this one has.

All ID help is much appreciated !

which makes it NOT ballouii, alas, altho the cracked brown cap did fit.

real hard to do mere photo IDs on russulas I hear…goodness knows I don’t have much success with it.

seems like a fine match with descriptions as well as most pictures on the web:

russulas take a bit more work to ID than just cap color or weathering…

too late for this one, but next time…

taste it (mild? acrid? strongly acrid? latently acrid?).
get a fresh spore print (don’t refrigerate first, it will kill the sporulation process); russulas have a spectrum of spore colors, from white to dark ochre. “they” are just kidding when they call this a “white-spored” mushroom.

find a good, local key (this is the hardest part).

good luck!
