Have you received this material? Have you had any time for a quick assessment? I’m still curious about this one.

not to mention the power of suggestion…

maybe it really is exannulate, too.

we look forward to your comments here, Rod, once you have a chance to examine the material.

(and I certainly haven’t forgotten the Leucoagaricus sp. on MO that we both thought was an Amanita, section lepidella, at least at first glance…).

The study of mushroom taxonomy is a humbling (but also very fun and challenging) pursuit!

OK, so the orangish tint is from the warts only.

Got it. Then we’re probably not dealing with A. levistriata.

This one will be interesting to examine microscopically.

I got fooled thoroughly in the field about two weeks ago in the Pine Barrens. The confusion causing agent was a white species growing (during our continuing drought…the efforts of the recent hurricane visible in my immediate area were PITIFUL) with 80% of the stem buried in the soil and what appeared to be a thin limbate or saccate volva. Remains of an annulus were quite clear. My brain was going down the Lepidella route TOTALLY…because of the habitat, the buried stem, the lack of pigment, a (imagined?) similarity to species of subsect. Limbatulae, and the fact that we had found two A. longipes and not much else in the genus (at the point before we got into the edge of an Atlantic White Cedar bog). The short striate cap margin I had convinced myself was because of the drying of the fruiting body in the sun and dry air.


Well, I finally got it under the scope and really had to re-orient my head because the spores were inamyloid! It turned out to be a white specimen of A. spreta. A thorough and goodly screw-up. Melzer’s Reagent is very useful for an occasional forceful reminder of the value of personal modesty.

So in the present case, I think I’ll just say, at least for the moment, “I dunno what this is.”


The color in the photos is perfect…

if I do say so myself!

Actually, I’m seeing very little red in the photos. I see a pale yellow cap that turn whitish towards the margin. Where the red comes in is the warts on the cap are an orangey color. The material around the rim of the volva is the exact same color and contrasted greatly with the white stem.

Looking at the dried specimen again, it has, as I said before, turned a uniform citron color and only shows orange at the disc where the dense patch of warts still exists. The volva is still the same orange color.

Thanks for the interest everyone!

Rod, I promise you will have the collections I made for you in hand soon. I’m still in the process of of drying and packaging…and collecting. Sometimes I don’t know when to say when.

well, the conjecture is flying…

photographer Bob, were these mushrooms actually as red as your photos depict? The base is particularly so.

Doesn’t seem like a very good match to the yellow predominant Amanita levistriata, tho the comments about the slightly striate cap edge (which I missed in the first go round) and the quite amanita-like bulb edge are good observations.

My first hit was some kinda odd Amanita, but it was Rod’s conjecture on it being a possible Lepiota that had me searching for likely genera within that group.

ID pending, eh?

I went through the

entire “Section Amanita” on the website last night. Levistriata looks like an intresting hypothesis. It has been very hot in NE NA this spring/summer. I have noticed that unusual weather conditions often correlate with unusual fungi. Great to hear the specimen is intact.

Imagine these images with the red tint less saturated…

and look at Chris Matherly’s photos of levistriata on the Amanita Studies site.


Good points, David…

I have been thinking about the volva on the bulb and feeling very uncomfortable about that characteristic. When the diagnosis went (briefly) to Macrolepiota for this observation, I got to feeling that we were heading off in a wrong direction. I’m glad to know that the specimen is coming to me some time in the future.

If it turns out to be an Amanita, which I grant you is a possibility, then I can’t think of what it could be given the source in Oneida County. If this was from the Gulf Coast, I might think it was close to A. levistriata. What would you think of that possibility?

Very best,

(and former Lepiotas) have basal bulbs, but the one seen in this obs appears to show the “rolled sock” volva. Also, sulcate cap margin seems unlikely to be Lepiota.

Thanks Debbie.

Admittedly I have a poor understanding of Lepiota type mushrooms. I find so few of them. I just realized that the only rule I use to separate Lepiota from Amanita is, “Lepiota have dark spots on a light background and Amanita tend to have light spots on a dark background.” Kinda like telling char from a trout. Crude at best, but I guess that makes this a Macrolepiota in my book.

Any advice on easily separating the two genera?

It could have lost the ring…

There doesn’t seem to be an annular zone, nor did I see any remnants hanging from the margin. The day I collected these was quite windy and kinda rainy. They were growing under pine though there may have been some hardwood saplings around.

The gill edges are slightly floccose. The cap has turned a distinct citron color on drying. The presence of such a defined volva and volval material make me think this is definitely an Amanita, but what the hell do I know…

Rod, you will be receiving this specimen along with the other material.

Could it have lost its annulus?

It reminds me a bit of what used to be called Lepiota acutesquamosa. Also, checkout the observations under Lepiota aspera on this site.

Very best,
