Since thiersii sits pretty much on the surface of the ground,…

the broken stem seems like additional evidence of the stipe penetrating the ground…as in longipes. Just thought of that.


Unfortunately no specimen…

and as you can see from the two photos it was not collected really well; cannot see base of stalk or rooting stalk or anything. Harumph.

On the tip of Long Island, A. longipes would be a very significant possibility.

The habitat is correct (pine oak-forest on sandy soil). And A. longipes is very common in this habitat. More over A. thiersii has a well-formed partial veil.

Very best,

Did you have spores or some other material that could support the determination that this is A. thiersii?.

Very best,
