I'm not familiar enough with Virginian fungi to even make a guess. But it is
possible that the fungi are like the Podaxales, and have spores on the
interior rather than the exterior. There are several small white
mushroom-like fungi with similar characteristics. But then again your
description sounds an awful lot like some button Lactarius I've run across.
In either case, slicing one specimen will aid dehydration and further the
examination of the interior, if there is one.

You might also send a dried sample to Dr. James Trappe, c/o Forestry Sciences
Lab, 3200 Jefferson Way, Corvallis, OR 97339 for possible identification. If
it is one of the truffle-like fungi, I'm sure he'd be _very_ interested.

My sole experience with Podaxis came from a chance fruiting in a neighbor's
backyard last year. A tiny stalked puffball apparently had been brought into
the yard with fill sand collected near The Dalles, OR. Whether this fungus
was fruiting from organic material or had formed a symbiotic relationship
with some of the herbaceous flowers nearby is a mystery to me, but it was
fruiting in a shallow trench between the grass lawn and the flower bed. None
of these measured over 2cm high, and certainly nowhere even 1cm wide.

And I remember seeing Podaxis pistillaris brought into an OMS Show one year
which approached 20 cm tall, not counting the cap.
