and it shows how variable (and similar) amanitas are…in color and aspect.

the color in this specimen has faded and become rather ambiguous, any amanita can show cap striations in age, and an annulus can be easily lost. and you MUST dig up the entire fruit body for important stipe base ID features!
Oddly, you are the third person who has mistaken velosa for pantherina (or vice versa) this week! which strongly illustrates the dangers of novice hunters attempting to eat amanitas…the mushrooms can fool you!!!

Thanks Christian!

It’s funny because I was looking for velosa. I have not ever found it before. When I first saw this I wondered. But because there were not enough markers I discounted it in caution.

A. pantherina

Sorry when I dug it up it broke into pieces so I did not include a picture of the base. I did not think this had all of the correct features of a pantheria, but I was stymied by this observation. We have lots of pantherina’s this color this time of year with the UV remnants washed off. The things that I was somewhat unsure of was the striate margin though this does occur with drying conditions. I also did note the lack of a partial veil and wondered if it had washed off.

It would help if you could explain how you concluded that this is A. pantherina…

We don’t see the typical volval remains around the top of the bulb. We don’t see a partial veil. We don’t see a deep brown color (which is often a clue for the true pantherina (but not always).

Very best,
