Observation 68142: Amanita submaculata Peck
When: 2011-05-21
Herbarium specimen reported

Notes: Growing alone, from soil, in mixed woods
Some large Quercus alba were nearby as well as some Pinus taeda

9.8cm broad, Convex, umbonate, dark brown in center fading to a brownish cream? (I really suck at describing color), it was “tacky” to the touch

White to cream, crowded, free

12cm long, Apex: 1.8cm wide, Base: 2.3cm wide, club shaped, white, three rings? on the soft white bulbous base, superior white membranous skirt-like partial veil, solid
Brown hues in the middle area of the stipe

Somewhat fishy, maybe like shellfish.

Specimen in personal herbarium.


the specimen was found in the lower center of the photo…The large Quercus alba were off to the right

Recognized by sight

Recognized by sight: the dark coloration on the stipe also matched the photo on Rod’s website. I think we could have a match!
Based on chemical features: odor is a very subjective thing…and a lot of older amanitas smell fishy.

I think I have only a portion of this specimen left. Friggin’ bugs ate the center portion of my specimen’s gills. Bummer. But I think there are still some areas that I can make cuts from. Summer is always bad for larvae getting to my specimens before they dry. That’s why I’m glad fall is here…well it’s kind of here. haha
I still need to measure the spores. I take forever to do these things and will more than likely do a lot more micro-work in the winter when fewer mushrooms are to be found.

an amyloid rxn….

removes this from the possibility of being in section Amanita (with those rings and a bulb), and is further evidence that it could be A. submaculata, in section Validae.

I’ll just bet that Rod would love to see your curious amanita…and compare it to a possible submaculata that he has also collected.

I dropped some Melzer’s Reagent on the gills and there was an amyloid reaction.

Yes, but those rings are not segregated into warts like these.

On the other hand, I think I have seen warts like the ones in this picture on material from Texas that was collected by David Lewis. He had a photograph of the fresh material that looked rather like Matt’s picture. If I remember correctly, Cristina and/or I went over that material in terms of a few microscopic characters and decided that the collection was probably A. submaculata.



I’m tired after that bible-length excercise regarding amerimuscaria…again…

I’ll just guess that the spores are going to be amyloid.

Let’s see how that turns out.

Very best,


you mention volvar rings in your linked-to description of submaculata Rod…

here’s the quote: “universal veil absent or as one or two thin whitish to gray rings around top of bulb or as loose limb against stipe or loose patches easily overlooked in substrate, more membranous and more likely to be collected attached to specimen than in the volva of (e.g.) A. flavoconia.”

Interesting specimen…

The radial “hair-like” pattern of pigment on the cap away from the disc is something that’s worth noting when you see it. Also notice that there are little pale “eye-shaped” regions with the width of the “eyes” aligned radially. This is a characteristic of one of the larger brownish gray species in the Validae — namely, A. submaculata Peck.

The smell of this species, however, is usually thought to smell like fruit, or apples, or licorice (anise), or new rubber tires (rarely). The rings of volval material is very unusual for submaculata.

Amanita submaculata has a large, skirt-like partial veil; however, it usually drops from the gills in two stages (thus getting a sort of crease around the whole annulus at its mid-radius) and ends up looking like a colonial period ball gown.



I’m interested to hear more when you look at the spores.

Very best,

I do have a scope.
I’ll put the spores in Melzer’s and check them out under the scope soon. I have a few others to check out before this one, but I’ll get around to it.

Thanks for the tip on determining section Amanita from section Validae Debbie!

got scope?

Meltzers on spore drop or a gill smash mount would tell you if this one is in section Amanita or Validae…

I don’t recognize it, but perhaps some of our eastern amanitologists will…
