When: 2013-07-05

Collection location: Rockingham Co, North Carolina, USA [Click for map]

Who: pete (petepann)

Specimen available

Cap 38.1 mm across. Convex. Please refer to photo for color.(This is where my handicap of being colorblind hinders my ability to properly identify) Appears greyish green to me. Silky veil remnants on cap and hanging from margin. Veil remnants stuck well to cap surface when dry. Cap surface smooth. No striations visible. Margin curved slightly inward

Gills white, crowded, unequal and adnexed.
Long gills 19mm. Short 3-9mm. tapered

Stem 88.9mm x 6.35 mm. Uniform width from top of bulb to cap.
Covered in veil remnants that. fall away easily during handling. Under that lies a very smooth, creamy white stem. Solid center from cap to bottom of bulb.
Bulb 50.8mm x 19.5 mm. at thickest point. Generously Tapered to a pointed tip.“Spear shaped” Flesh white and solid through and through.
No bruising or staining present anywhere on specimen.
Very mild Mushroom scent emanating from cross cut section only.
Growing in Pine thicket. Oaks present but not extremely close. Pines dominant.
Spore print started this morning. No yield at this point.

This specimen identifies VERY close to Amanita magniradix with a few exceptions that still leave me undecided.

In the photographs, the cap is far from fully expanded.

Hence, the gills may not have fully separated from the stipe (to which they were connected by tightly packed hyphae and chains of inflated cells during development in the primordium).

We can only use the images as clues. Images can’t always provide a certainty of ID.

Very best,


What about gill connection?

Gills seem to be free from stem on Amanita onusta. They are attached on my specimen. Not trying to second guess you, by NO means. Just trying to understand. Are gill structures not an important key here?

It appears there are recurved scales near the top of the bulb…

in the second photo.

Very best,


Since the rooting bulb clearly comes to a well-defined end,…

we can eliminate A. magniradix in this case.

There looks like there is some gray, fine, powedery material on the cap. At least it is not white powder. That seems to fit your notes at least somewhat. I’m sure that the rain did a number on the cap’s volval remnants. But if they were gray then that eliminates A. rhopalopus.

It looks like the upper part of the bulb may have had a curved back scale or two in one of the pictures or at least dirty short lines in others.

If those last observations are close to accurate (and given the size measurements), then this could be Amanita onusta.

Very best,


Second Guessing Myself…

At the beginning of my identification research, I chose these latter three specimens because I thought they were the same species due to the elongated bulb. But further into the analysis, I gave up on that assumption due to the fact that the bulbs were the ONLY similarity of the three. Even the bulbs had their differences. So it really blows my mind, that when it all came full circle, they WERE all related. I have so much to learn. SO much to learn.
