For what it’s worth…

I wonder if “A. russuloides” may be the same species as the one currently documented on ret’s website as “section Amanita sp-34”.
http://www.amanitaceae.org/?Amanita+sp-34
I find lots of this type every summer, and it always occurs to me that they look like Russulas. Ret reports this species as having a partial veil, but in my experience (seeing hundreds over the years) I have never observed a pv on this type, and I have closely observed some very new buttons. At any rate, even if there is a fleeting pv on this species, it is easy to believe that it has been recorded as exannulate. Spores on my sp-34 collections have minimum lengths a bit smaller than the 6 mu reported for russuloides. But my estimates of 1.3<Q<1.4 match russuloides. Also, according to the account on ret’s website, russuloides is small (cap diameter about 25 mm).

…is supposed to be exannulate.

I find Amanitas…

that fit the description of praecox well into the summer months. A similar/same type appears in fall. Here’s an example illustrating the apparent uncertainty associated with placing a name on this/these types, obs 114780.

For this observation (139855), Eric reports hemlock in the area. This supports the praecox idea.

Eric some of your russuloides look to me just like your praecox…

…and this goes for many of my personal collections / photos too. Could it be that praecox actually fruits spring AND fall? Does anyone know? I’ve tested KOH on russuloides and it’s + but I wonder if A praecox is also. Maybe I should look at RET’s website.

Thans Eric,

that this observation is the same entity as:

http://mushroomobserver.org/139475?q=1MrEK

http://mushroomobserver.org/138651?q=1MrEK

http://mushroomobserver.org/106095?q=1MrEK

as they were all found along the same short stretch of trail featuring beech and hemlock with pine, oak and more mixed in. I’ve found what I’m sure is A. velatipes and I’m not sure these are it. I’m not sure how much the frequent heavy rains is affecting the morphology. With more moisture present increasing the rate of hydraulic expansion theoretically could change where and how the annulus separates and obviously can erode cap color and other features. These tend to be on the small side of the size range for A. velatipes.

Thanks Christian.

I rather like that proposal. I think the caps are very reminiscent of Russula. I’ve been wanting to call these A. velatipes but the annulus position and cap shape and color and the volva don’t quite line up.
