Notes:
Growing in mixed woods.
Caps up to 7.5 cm across and somewhat appendiculate.
Gills “cafe au lait” colored.
Spore print white and spores amyloid.
Spores ~ 8.0-10.1 X 4.9-6.0 microns, mostly elongate and smooth.
Q(range) = 1.59-1.79
Q(avg) = 1.67 n=18
Did not detect a distinct odor>
With the tannish gills, A. microlepis seems a possibility but the spores are perhaps too wide(?).

I’ve gone back to accessioning after a couple of weeks of work on setting up a sampling regimen for my herbarium with regard to the Boston Harbor Islands inventory project. The boxes really can build up when I take time off from accessioning.

This material is accessione and is now in the sampling queue.

Very best,

Rod

Looking at the base of the bulb with its prominent limbate volva, perhaps both sect. Phalloideae and subsect. Limbatulae of sect. Lepidella sensu Bas (1969) can be proposed; however, the appendiculate cap margins seem to eliminate the former proposal. It’s interesting that if this species indeed belongs in subsect. Limbatulae, its spore shape is not representative (by and large) of that grouping. A. microlepis appears to have a different UV structure.
