It’s okay for me (Amanita velatipes). I learn!

I see you have some doubt.

I must admit, the very yellow ones which I mention below and these robust examples seem like different species to me. But I assume the velatipes species has been sorted out on the basis of molecular data.

Thanks, Claude, John, and Igor…

for helping me to update my concept of velatipes. The prominence of the lined or furrowed cap margin appears to be a variable trait. A large button pictured at Mushroom Expert is another example of a virtual absence of this trait, at least in the early stages of development. I revisited the collection site today and the marginal lines on mature caps were faint at best, with a few examples still rather smooth. I’ll post another observation later today.

Although I believe to have correctly IDed velatipes in the past, these were all much smaller, much yellower woodland specimens. All caps observed, except for young tight buttons were prominently lined on their margins, albeit with short lines. I believe that at least some of the large examples of what I had, in the past, called multisquamosa are actually velatipes. A comment ret had once made regarding the length/prominence of striations on multisquamosa seems to imply that length of striations is very helpful in distinguishing between velatipes and multisquamosa.

See notes for recently added data as per this obs.

In Quebec, Amanita velatipes comes with furrowed margin and a toothed ring and ample; grows under the oaks (Quercus) and caryers (Carya).

Thanks Judi.

I couldn’t have wanted these guys to pose any better that they did. A really beautiful fruiting. I’m headed out the door in a few minutes to visit some good bolete spots, including this location.

Looks like I’m probably incorrect in my original assessment of this collection. Part of leaning all the mushrooms. As has often been said, “Mushrooms are humbling.” With knowledgeable folks here at MO willing to discuss, one easily makes excellent adjustments. I suspect the end result here will be that I refine my own concept of Amanita velatipes.

this is a beautiful set of photos.

Looking at the Amanita website account of canescens…

I see that one character to be expected with this species is orangish deposits on the lower stipe, which are clearly not present on these perfectly formed specimens. So I’m quickly losing confidence in my original proposal.

For years, I’ve seen numerous pantheroid Amanitas at this collections site. I’ve always called them multisquamosa because they consistently lack yellow on the caps. But never have they been this robust. I suppose the unusually large size could be attributed to the 4 inches of rainfall we’ve had over the past week.

I’ll still hopefully collect some mature examples tomorrow… and some fresh King Boletes at the same spot :-)

The large caps…

show no striations. The clustering of large fruit bodies is unusual for Amanita. Canescens is one species that does this. The solid, splitting, napiform basal bulbs do not seem to fit either velatipes or multisquamosa.

The first thing I thought when I saw these was “Look at those overgrown multisquamosa!” They may actually be this species, with striations not yet having formed on the cap margins. I tried to find some spores in a Meltzer’s smash mount of a small piece of gill, with no success. The fbs are too immature.

I’ll return to the collection site tomorrow, and if they haven’t all fallen victim to a lawn mower, I’ll pull a few mature examples and make certain to get a nice thick spore print. So, stay tuned…

… is in subgenus/sect. Lepidella and should have amyloid spores. The gestalt stature of the mushrooms in this obs suggest subgenus/sect. Amanita.
