Observation 141823: Amanita sect. Vaginatae sensu Zhu L. Yang

Notes:
A single specimen growing in grassy soil under hardwoods (these woods are mostly oak with some hickory and beech).

The basidiocarp’s apparent height 17.5 cm (the stipe is curvy, so it’s actually taller).

The cap is convex (not fully expanded), 6.5 × 5.7 cm in diameter, medium brown (no gray shades) with a slightly darker umbo region (~2 cm in diameter). The cap surface is dry, glabrous and somewhat shiny; no volval patches were observed; the striations are pronounced and are 1.5 long.

The gills are off-white and appear to bruise brown on the blade edge at the cap margin.

The stipe is exannulate, at least 17 cm long, narrowing from bottom to top. It’s 0.6 cm in diameter at the apex and 1.6 cm in diameter right above the saccate volva. The surface is a bit scruffy (not pruinose) and tinted brownish. Where the scruffy “veneer” is missing, white flesh is exposed.

The volval sack is whitish, thin, membranous and soft to touch; it’s up to 3 cm tall.

No odor was detected.

Rod, I am including this one in the shipment, too.

I don’t even remember picking his one, while I can still recall collecting things from earlier forays and even the exact locations where I found them.
I am certain I haven’t seen this one there since 2013. Judging from the description of the habitat, it came from the same section of the woods where I make most of my collections at WCSP.
Rod, is this something you would consider adding to your sequencing queue?

Thanks Igor,
