Observation 55592: Macowanites Kalchbr. nom. inval. (Site ID) (Russula)

When: 2010-10-15

Collection location: Orangeburg, Rockland Co., New York, USA [Click for map]

Who: damon brunette (damonbrunette)

No specimen available

This one came up at an ID session in NYC. The gills are VERY distintive on this one, so i thought it would be easy. The closest i came up with is Hygrophorus nitiosus, not nitratus. It was listed in an old hygrophorus book.. cant remember the name right now, as having a nitrous smell, and being cross-veined, which this had.
But then another member of the club came across the KUO post of Arcangeliella desjardinii. Its gills look EXACTLY the same, but has no odor and is a west variety so far as we know.
Any ideas?

But I do not know these mostly western North American species. Debbie’s posting. http://mushroomobserver.org/7665?q=2Oiq shows latex. Yours does not so I would lean toward Macowanites. Without a specimen, we will probably never know for sure.

Thanks darv

Yes this mushroom was past its prime, so maybe i was trying too hard to make the odor match a description. Id go with the first one, even though there was no latex. Still wondering if Walt has seen this on this side of mountains.

milk or not

Arcangeliella if it has latex; Macowanites if no latex.
The odor might be from AGE, it looks past it’s prime.

Seems like something Walt will know..
