Observation 98296: Amanita “sp-34” Tulloss crypt. temp.

When: 2012-06-25

Collection location: Hunlock Creek, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

Same exact location as the linked obs made last year.


I believe these are the same species.

Newly emerged specimens. I carefully checked the spot yesterday and there were none of these at that time. 0.5" rainfall last night brought them on.

Bright yellow color on disc and whitish grainy deposits on caps. Basal bulb rather abrupt. No ring or remnant of a ring on stipe of any specimen in this collection. Volval deposits variably distributed on basal bulbs. A few of the photos show a piece of material that dislodged from the very bottom of one stipe…. positioned next to the mushroom from which it came.

Accessioned today. Since I’m looking at a lot of your posts all at once, I think that his is quite like Amanita sp-34." I noticed that despite the apparent youth of the material the spores are broadly ellipsoid to ellipsoid when your camera caught them in side view.

Very best,


The link shows an amanita that appears to be a small ringless specimen…

of A. crenulata. My own collections of A. crenulata – all made during autumn – included some specimens that appeared ringless. Apparnetly, A. crenulata has an annulus that is quite fleeting. I have not previously seen such a small – sized example of A. crenulata.

The mushrooms in this obs (98296) never had a ring on the stipe. I have observed this type in the same couple of square yards on my property for a few years now. Perhaps I did not sufficiently point out this consistent trait?

Cap color of A. crenulata is remarkably consistently champaign tan. The ones in my obs (98296) do not show this color.

is that so?

A. crenulata is a robust species…

that I typically find around here in the Sept-Nov time span. The cap color of A. crennulata is quite consistent. I doubt these (this obs) are examples of A. crennualta. A. crenulata has a ringed stipe… at least for young fruit bodies.

Herbert, these little amanitas never show any sign of an annulus.

Also, the mushrooms are always very small, with cap diameters rarely exceeding one inch. The basal structure, although quite abrupt, does not show the consistently well formed “gutter” collar that I associate with subsection Pantherinae.
