ID request (possible amanita pantherina)

Habitat: Found growing in grass along the edge of a trail, on a west facing slope. The mushroom was slightly dried when found due to the intense sunlight it was receiving. The mushroom, and several of it's brethren, were growing near the roots of mixed conifer and eucalyptus trees. The mushrooms were found in Northern California, San Francisco area. I spotted about 7 or 8 specimens, growing in clusters of 2 or 3.
Gills: I don't know if the gills were attached (stem broke off during transportation.) I put the stem back where it would have been and there seemed to be a gap between the gills and stem. They are the same creamy white color as the stem. I am working on a spore print now.
Stem: 4.5" long,3/4" diameter, creamy white, slightly scaly at the bottom (possibly veil remnants?) but smooth above the ring, hollow and pithy stem, relatively thick, with vulva
Cap: 4" Diameter, distinctive brown, similar to a dried leaf, almost brass colored in some specimens, creamy white spots that are identical to amanita muscaria specimens I have seen, they range in shape from rounded polygons in the center of the cap to flatter, more horizontal spots which run parallel to the edge of the cap. The texture is dry and smooth, other than the white bumps. This specimen is a flattened hemisphere, convex. Younger samples were more spherical. There is a sort of lip running around the edge of the gills, they dont extend all the way to the edge of the cap.
Spore print color: spore print in progress
Bruising: The flesh has darkened from a creamy white to a more brown, oxidized look, on the stem. like an apple which has been sliced 15 minutes ago.
Other information: The mushroom has a very mild smell, possibly due to it being kinda dry. The smell reminds me of amanita muscaria. It smells mild, sweet, fungal, with a hint of rich meaty chicken. It smells like it would be a fairly tasty mushroom, with hints of the forest and decaying vegetative matter. The smell is not offensive, no hints of ammonia or fish.
I have some pics, hopefully I can get them up for viewing.

I have more pics, if you guys need them.

I'd have to agree with pantherina because the only other similar looking specie in that area I can think of is the amanita brunnescens which usually has discoloration and or an abnormality at the end of the stem. Nice find I love hunting amanitas, they're all over New England. Too bad they're both poisonous :/

I agree that it's a panther. The only other thing that would look like that would be a blusher, which in california would be Amanita novinupta, but that should have noticeable blushing.

I can't really speak for the new england blusher (which is a brunnescens) but the one on the west coast (amanita novinupta) is edible when cooked and delicious - not poisonous. The european blusher is also edible.

It is Amanita pantherina.

Ah yes I forgot the west coast get the novinupta, I stay away from the amanita brunnescens edibility wise in general. Thanks for the blusher confirmation, I only seem to find the poisonous amanitas around here especially those nasty death caps and angels!

That is really wonderful, thanks for the input everybody. I have been hunting for muscarias unsuccessfully for much of the winter, and I found quite a few of these today when I wasn't even looking! I hope you all are right about the ID, if so, I might be able to get a years supply of amanitas relatively easily. From what I understand, these mushrooms are much more potent than muscarias, so a mushroom this big could yield several doses. I am hesitant to bioassay this sample yet, and if I ever decide to I will be very careful. There are some articles on the internet speculating that pantherina may have cross bred with other local amanitas which contain kidney-destroying toxins. This seems pretty unlikely, at least with this specimen, because the hybrids were supposed to be yellow, and may have had other morphological differences.

No they don't do that.

OK, thats good to know. It seems like there is a lot of misinformation about this mushroom out there. Some people claim that amanita pantherina doesn't even grow on the west coast of America, only in Europe. I'm much more inclined to believe the sources I saw that said that it is naturalized here, and common in parks (which is where I found them.)
Thanks a lot!

I found Amanita pantherina in California yesterday. Maybe it is different than the european taxon but no one has published any pantherina like species from the west coast yet so I am going to call it that.
Pictures will be on mushroomobserver.org soon.

I found more of these today, but I don't know if they are the same. The other specimen I had is fully dry now so it's hard to do a comparison. I'm wondering If the one's I found today are gemmata? The warts are not raised, they look more like spots of fuzzy white stuff rather than bumps. They don't rub off, at least when dry. There are tons of these, growing in eucalyptus woods at a park. The younger ones have raised bumps, whereas the older flatter specimens seem to just have flat white spots. These are actually an almost metallic golden brown color on the caps, very beautiful.

Those are also Amanita pantherina.

ok, thanks! I don't know if it matters, but I was able to wash the white spots off of the cap of the second specimen with a little water and some light rubbing. The first specimen appears to actually have the raised warts, not the powdery, fuzzy white spots. I was reading about a species called amanita ameripantherina, which seems pretty similar to this one, and is known to grow in my area. The spots on ameripantherina wash off, and look less like warts. I read about one case of ameripantherina poisoning, but the didn't say if it was a case of muscarine intoxication, or actual amanitoxins. The person lived, and said the mushroom was very tasty. I'm still very hesitant to ingest either of these finds.
Also, these only have one vulva cup, I read that true pantherinas have a double vulva ring?
Thanks again for the input!

I think the scales on the caps of Amanitas wash off all the species that bear them.
