Observation 138818: Amanita velatipes G.F. Atk.

Notes:
Ground color on cap is somewhat brassy. Growing in grassy area amongst planted hardwood trees which I believe are not native to our area… one type of beech and another that i don’t know.

No they are far from all sampled. I’m working on an arrangement to have that done now. What we want to do is look devise a sample scheme that will cover all the counties for which I have at least one collection of A. velatipes, A. multisquamosa, and Amanita sp-AZ07 (another distinct species that is mistaken for multisquamosa in the western states of the US). There will be more news on this soon…I hope.

The total number of collections is over 100. I think under 10% are sampled. I’ve not been working on section Amanita for several years as you know.

Very best,

Rod

Among the velatipes seen on WAC…

the prominent “gutter” comprising the upper margin of the “rolled sock” is seen on fruit bodies in photos #2, #4.

In photo #1, I see one fruit body with prominent “gutter”. On another, the margin appears to be ripped apart with material deposited higher up on the stipe.

Photo #3 shows two young fruit bodies with basal structure somewhat ambiguous.

So, it appears the consistency of the “gutter” margin of the “rolled sock” volva (or lack thereof) on the “funnel veil” Amanitas may be a dubious correlation to taxon.

I’m wondering if all of the ones pictured on WAO had been sequenced…? Photo #1 shows the pale yellow cap color (and on the left, a white margin) that now brings to my mind subvelatipes.

I’m not sure if that difference hold up.

I’ll have to watch for it.

What do think of the rolled socks on the pictures posted for velatipes in WAO?

Very best,

Rod

I feel like I’m finally…

straightening out my concept of velatipes, now that we have the name subvelatipes as a potential option for the relatively small/slender/pale ones. I think another difference between velatipes and subvelatipes may be that the latter tends to have a more prominent margin atop the “rolled sock” volva.

Here is a case of velatipes with a brown disc on the cap.

Identified by nrITS gene sequence.

Thanks for sending the material, David.

The cap is robust and lacks long marginal striations seen in mutlisquamosa and subvelatipes.

“Great Funnel-Veil Amanita” might be a good English name for velatipes.

Very best,

Rod

I’m used to seeing long marginal striations on A. multisquamosa.

I remember seeing your pictures of very robust A. multisquamosa-like specimens; and, you’re correct about the coloring of the cap (although Jenkins maintained that the yellowish tint that we normally see on velatipes was not always present in his experience.

I’m afraid this leaves us in an unsatisfactory position for the moment.

I hope that we can progress on this point within the next few years.

Very best,

Rod

Thanks Bob, Naomi, and Rod.

This one really fooled me! Actually, looking at this again, it reminds me of a type of large panther that I have called Amanita multisquamosa, and which I have also collected at Moon Lake. The color of this type seems unusual for A. velatipes. Color, as seen in photos, is quite accurate.

This material has been received and accessioned into Rod’s herbarium. Rod looked at the specimen under the scope and found no clamps attachments, in addition the shape of the younger specimen (in your photo) and the rolled sock volva are reminiscent of A. velatipes. This specimen appears pantheroid.

The larger one showed no annulus.

Although one may argue the annulus may have fallen off, this is not a typical muscaria trait.

These are large robust mushrooms. My take on the basal structure is that the bulb seen in the photo had not yet fully developed to the point where the concentric rings (associated with muscaria types) were evident.

But I agree Bob, about these looking like a pantheroid type.

The larger one is dehydrating and I’ll eventually mail it to Rod.

Thanks for posting the comment… a reminder for me to stop on my way home from work tomorrow and see what has developed with these.

an annulus present? What was the size? These don’t strike me as being A. muscaria. They kind of remind me of A. multisquamosa or velatipes.
