Observation 175356: Amanita sect. Lepidella sensu Bas

Notes:
> Once again, two separate collections made by the Burghards of what appears to be the same species; both collections were made at or near the North Gate site
> The older/large fruiting body dropped spores
> I removed the partial veil from the other basidiome but unfortunately could not coax it into droppings spores; this one was dried.

Microscopy:
Amyloid in Melzer’s;
[20/1/1]: L x W = (10.9-) 11.2-13.5 x (4.0-) 4.2-4.7 μm
L’ x W’ = 12.4 × 4.4 μm;
Q = (2.47-) 2.62-3.11 (-3.22); Q’ = 2.84; cylindric to bacilliform

The only close fit for the above measurements corresponds to A. scalaris, but the morphology suggests otherwise.
