Recognized by sight: one of two good possibilities. boudieri is more stocky than gracilior, but not always.

Recognized by sight: oak habitat fits, but warts are flattened not conical. morph varies, tho.
could be either boudieri or gracilior. The Galli book shows both stocky and thin A. gracilior.

http://mushroomobserver.org/134101?q=1M5V7 I would tend to A. gracilior, could be the warts be considered “conical to subconical” as in http://www.amanitaceae.org/?Amanita%20gracilior ? About the season I would consider a extension of Autumn since I felt a extended Autumn season on the rest of my observations this year (we had a warm and rainy winter). The doubt is about the not so thin stem and the warts. This was found near Quercus suber, with presence of Cistus salvifolius and pines nearby as well as oaks. This one near civilization, the other observation, far from it. Weirdly, the other was “covered with adnate, subtomentose-subfelted to pulverulent-subtomentose, white, volval layer, sometimes decorated with small, pustular warts” but the stem was thin!

Or, possibly, A. boudieri.

According to Neville and Poumarat, the two can be separated by the seasons in which they fruit.

They also can be separated microscopically.

Very best,


Amanita gracilior?

has their own time and availability. I’m sure you did your best and the only thing that I need is to thank you Rod, for your sympathy.

Thanks for posting the addtional cap images.

I think they really help. Maybe A. solitaria would be a possibilitiy. Note form of warts on some of the caps here


and also note the partial rings of volval material on the top of the bulb in Dr. Bas’s drawings of the species (first “bubblegum card image” on the brief tab at the above URL).

Thanks again. I’m sorry that it took me five days to get back here.

Very best,


Thank you Rod :)

Here are more cap photos. Sorry, but I am still reading the camera manual to see if I understand your suggestions (I never looked at it rs). Tell me if you need more details. I’ll send the email, thanks again.

David, thanks for calling my attention to this posting.

I agree that this mushroom probably belongs in Amanita section Lepidella.

It’s too bad that we can’t see the whole surface of the cap clearly in the first photograph.

Amanita strobiliformis often has distinctive universal veil remnants on the cap. Amanita silvicola is, unfortunately, limited to southwestern Canada and the Pacific coastal states of the “lower 48 states” of the U.S.

Elsa, if your camera can be set to a fixed lens opening (f-stop) that is f16 or maybe higher, I would suggest trying a slow exposure speed (automated if possible) at the tiniest lens opening you can get. This will help you maximize the depth of field and more of the mushroom will be simultaneously in focus.

If you contact me through < http://www.amanitaceae.org?Contact+us >, then I will be able to send a PDF to your email address that you may find of interest with regard to collecting, photographing, and describing amanitas.

Very best,

Rod Tulloss

It would be fine yes…

I have no hit in any correct ID.

Elsa, the combination…

of non-striate appendiculate cap margin, white color, annulus, robust stature, and warty cap surface suggested section Lepidella. A quick check of the Phillips field guide and Dr. Tulloss’ Amanita Studies website produced a few reasonable possibilities. The website mentions, about A. silvicola, “The bulb may lose its abrupt character with age and become closer to clavate without a distinct margin.”

But I think your A. strobiliformis idea seems better than A. silvicola.

Aside from what I learn from the literature, and from interacting here at MO, what I know about mushrooms comes mostly from collecting here in eastern North America. I have not ever IDed silvicola. But sometimes a second-hand-guess may help move along a discussion in a productive direction.

maybe you will get some answer from him? for my part all I can say is, that this is a nice amanita and a nice find!

Interesting site…

I saw an Amanita strobiliformis that could match, what do you think Dave? http://www.amanitaceae.org/?Amanita+strobiliformis

I see two differences
By: Elsa (pinknailsgirl)
2013-01-28 16:35:52 CST (-0600)

First is the ring, in obs. is smooth, in Silvícola is some kind of floccose. And the “the large basal bulb encased in the remains of the volva which creates a trough around the stem” that is Rogersmushrooms description of A. Citrina, with the variant alba being all white. I don’t see that trough on A. silvicola. I didn’t know A. silvicola (I don’t know either if it exists in Europe).

The difference between A. citrina and this, is the ring… it’s not skirt like, and the basal bulb is not so abrupt.
