Notes: > A family of three basidiomes growing on the side of the Red Trail near Bertha’s canal in the typical pine-oak barrens. The duo in the first pic were growing next to each other; the third specimen was found two feet away.
> All had bulbs shallowly buried in soil under needle duff.
> The largest fruiting body (the only one collected and preserved) dropped spores
> Cap = 6.3 cm in diameter; overall height = 7.5 cm; bulb = 2 cm at widest point; stipe = 1.5 cm at widest point (near the apex)
> The spore shape as seen at x400 and the presence of “terrace-like or disc-like rings at bottom of stipe or upper part of bulb” strongly suggest A. scalaris
Spores are amyloid in Melzer’s;
[21/1/1]: L x W = 12.5-16.3 (-17.7) x (4.2-) 4.4-5.6 μm;
L x W = 14.6 × 4.7 μm;
Q = (2.50-) 2.70-3.50 (-3.68), cylindrical to bacilliform, with 2/3 of the measured spores having Q value of 3.0 and above; Q = 3.09

That data and the rings around the stem base fit the concept I have of this taxon. I hope that we can get DNA as well.
This material has been received and accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.
From my point of view this is a very good find.
The original site at which I collected “scalaris” is in Jamesburg Municipal Park near Helmetta Pond. Much of that site has been destroyed by illegal off-road vehicle traffic…including the place from which I first obtained collections of this species.
I do think that your material is extremely similar to the collections I made in Jamesburg.
If any or your material is available for study, I would like to examine it.
