The crux of the matter

Ah, when I was young and innocent – about two months ago – I thought gross morphology was sufficient. This website’s contributors (and books) are contributing greatly to improving my observations. Ravenhawk is right – I obviously did not provide enough information for a definitive identification. I am getting better, and appreciate your indulgence.

And as picker, I have to agree that these exemplars were not crumbly like the standard Russula in this area. I would happily accept H. russula and let the parade move on.

Thanks to all for helping me along the way.

I have easily broken the Stem of H. russula by twisting it. That is an interpretation issue, if it bends or snaps with enough pressure you can get any gilled mushroom to snap at he stem. Did it crumble? Russula as you know have very brittle stems and cap. On way i like to determine if its a Russula is to throw it at my mushroom hunting partners and it it disintegrates into a 1000 or so tiny pieces upon impact it is a Russula. If it it bounces off and falls into several pieces then its something else. But Seriously the gill detachment is about right for H russula and you have to give some credit to Walt an Noah for being somewhat of experts on eastern species of mushrooms,THEY ARE. I have found and abundance of H russula myself in October all growing in arches and fairy rings and all being a bit variable from. each other. In West Virgina which happens to be pretty close to Tenn the Russula population is greatly diminished by this time of year but the H russula are some what abundant. To Be honest we really do not have enough info to make a 100 % ID but I always like to read good discussions on this sight when it come to ID"S
Jim i would recommend that in the future,When you hunt the shrooms that you make note of the types of tress There growing with, texture. taste. (a little nimble wont hurt you) smell. Take your pics at all angles and upside down and if you have an abundance of shrooms in your observation take a pic of all the different forms that they are in.

The stipe was brittle.

That squarely puts it in Russulales.

Hygrophorus and most likely H. russula. The gills and gill attachment are wrong for russula, also the “dew drops” on the stipe are typical of Hygrophorus. H. russula is a variable species, it’s also the same thing around the world, European, Asian and North American… a rarity among ECM fungi.

I don’t mind the tennis match, but could those who change the name offer a reason other than “recognized” or “it fits”. As I pointed out below a ways, the current exemplar does not “fit” the images of H. russula on this web-site. So some other citation would be helpful to those who are trying to learn through this process.

Hygrophorus russsula fits.

Since the stem snapped like chalk I think it is Russula rather than Hygrophorus.

The stipe snapped of with an easy twisting motion – it didn’t try to bend and resist.

Could you bend the stipe or did it snap?

My earlier comment left out a “not” in that this specimen does “not” resemble the illustrations on this site for H.russula in cap shape, gill coloration or stipe morphology. The “not” is the important word here.

OTOH, the present exemplar does resemble the illustration for H. russula in the Italian S&S guide by Pacioni more closely than the illustrations here.

Sorry – I can’t comment on the brittle vs. crumbly issue with conviction. I recall it being relatively sturdy.

If it’s brittle
By: Paul Derbyshire (Twizzler)

it’s Russula, otherwise possibly H. russula.

No, they did not ‘bleed’ – most likely they are not Lactarius.

I lean towards Russula. Hygrophorus russula does not make a good fit because this fungi’s cap shape, gill attachment and coloration, or stipe morphology does not resemble the imges of H. russula on this site. (See 60768, 29042, 59777, and 34938, for examples) [edited to include the ‘does not’]
