When: 2013-07-05

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

Who: pete (petepann)

Specimen available

Cap(Mature) 88.9 mm. Convex to plane
Smooth, dry texture
margins curving slightly inward and striate.
White when fresh dulling to off-white overnight with darkening center.
“Pacodermish” wrinkles forming from center outwards overnight

Gills crowded, unequal and Free from stem. Indistinct “collar”?
Long gills-25.4 mm Short gills- alternating from 4 – 12mm
White when fresh, dulling to off white to tan overnight.
Spore printing started this morning. So far no yield.

Stipe 165 mm. × 12.7mm (from cap bottom to bulb top.)
white, smooth exterior dulling to tan overnight.
White Silky substance where stem meets cap.(I am guessing Cortina remnants?)
Solid interior. White when fresh, dulling to tannish overnight
No apparent bruising or staining
Elongated deep rooting bulb 51 × 25.4 mm. tapering toward bottom.
Solid to somewhat fibrous toward center.
Uniformly white when cross cut fresh dulling to off white with exposure.
Slight “mushroomy” scent after cross cutting bulb. Very pleasant, sweet aroma.
Found growing in pine thicket, with a couple Oaks not TOO far away.(My apologies for the terrible habitat photos. Storm was upon me and was rushing to get equipment put away.)


Gills a bit off color from overnight storage
Embarrasing shot
Terrible. just terrible
Gills free to what looks like a very faint “collar”

With age gills often become remote (very, very free). There is another factor in the case of the species suffering from the yellowing syndrome. This syndrome changes the thickness of the gills often significantly. Bas noted this and provisionally described a species A. crassifolia based in part on yellow staining and thicke gills. He mentions that he thought it might be a diseased specimen of A. subsolitaria. I have found collections suggesting that the latter description is probably the correct one.

So in the case of the yellow specimen the gills are altered by an unknown organism invading and altering the fruiting body; and, in the case of the present specimen, age (cap expansion and stipe shrinkage) has created remote gills.

Very best,


Cap margin DOES hang past gills.

But once again.. Gill attachment VERY free on this one, whereas they are attached to stem on “yellowing species” Also this one not yellowing at all. It is extremely distinct in the other. Does maturity of mushroom effect gill attachment and staining? Maybe?

Does the surface/skin of the cap extend beyond the ends of the gills?

Like a free flap?

The reason this comes up is that a yellowing specimens of a deeply rooting species of Amanita sect. Lepidella has been posted by you here:


It strikes me that the “yellowing syndrome” specimen and this one might be the same species.

Very best,

THATS what I was looking for! I remember you referring to that name in an email last night but I could not for the life of me find that particular conversation in my saved file. And I know good and well I saved it. I was getting very frustrated today with things going missing in this computer today. Also, a dehydrator is in the works. So I should be able to start sending samples to you soon. And yes, bulb did have a curvature to it. I have one more specimen that I need to finish documentation for and post. Do all the overly long bulbs insinuate Lepidella? You may recall the specimen I am speaking of. It has the Cortina type veil. I will have it posted shortly. It would be nice to be able to post it with the proper name the first time.

Hello again, Pete.

I did not miss the fact that you broke up the measurement of the mushroom length into three parts: cap thickness over stipe, thence to the top of the bulb, thence to the base of the bulb.

Good goin’.

Very best,


Pete, I think this could be an Amanita.

The wrinkling is from in site drying. The bunch of gills that are brown indicates that a sector of the cap is decaying.

The solid stem and the relatively long-rooting bulb suggest that this species could be a species of section Lepidella.

Did the bulb seem to kick off to one side?

Very best,

Not sure about the “earle”. Site added that in

I researched this till I was cross eyed. I gotta hand it over and move on.
