Observation 145506: Amanita spreta (Peck) Sacc.
When: 2013-09-14
(41.894° -72.296° )

Notes: Three specimens (2+1) growing under pines, with mature oaks in the vicinity. The mushrooms had a limbate volva, an annulus and a lined cap margin at all stages of development, and the presence of all three suggests Amanita sect. Caesarea. I’ve never collected representatives from this section in my home state (NJ), and I don’t know what the distribution limits of this section are in the Northeast.

Macroscopic properties of the largest specimen:

> The fruitbody is 15 cm tall
> The cap is oval-shaped (11 × 9 cm); grayish-brown (darker at the broad umbo, paler toward the edges), with a white patch of the partial veil near the center; the striations are 6-10 mm long; many short gills of varying length were observed
> The stipe is 14.5 cm long, 1.4 cm x 2.2 cm in diameter (apex and just above the volva, respectively); it’s annulate, with a narrow channel running through the entire length (i.e., “hollow”); whitish overall, brownish below the ring and decorated with a snake-skin pattern above the ring; the annulus is thin, membranous and rather delicate; the volva is 2.5 cm tall (from base to the tip of the longer limb), limbate, white, thick-wall, and somewhat friable.

> No odor was detected at the time of collection

…for the ID, Rod. You are correct about the camera flash introducing longer wavelengths of light. The three “red-shifted” pix have already been marked accordingly. The cap color in #084 is very close to that observed by the human eye.

I will be shipping this one along with Nos. 145497 and 145499 to you soon.

Again, the camera seems to be adding a reddish tint to the images.

I think Santiago Sanchez might like to have a sample from this, which I would be glad to forward to him.
