Text of accompanying letter:

St. Louis Mo. July 14th 1899

Mr. C. G. Lloyd,
My Dear sir:—
Your prompt response, and further offer to kindly aid in my
efforts to know our fungi, requires & has my hearty thanks. Reading
your description, I have now no doubt of the correctness of your iden-
tification. Today I found 2 specimens of another Lepiota new to me.
Reading your descriptions, I believe I know it. is not the long root an
important characteristic? I enclose an of-hand section. I was much
delighted finding this — appeared so entirely strange with its dark
pyramidal erect scales. Should you have doubt of my identification, I
shall have to send a specimen. I think Lepiotas are not plentiful in
our vicinity. Is the above (the L. acutesquamosa) edible? It has a
rather strong odor.

Yours very truly,
N.M. Glatfelter M.D.

No sample number on drawing or letter, but the date
matches the letter, in which he says,“…Today I found…”

This appears to be very much like A. onusta

Left side:
Ground surface (marked by line — ph)
Markedly squarrose above the bulb

Right side:
Specimen old, scales very dark umber. Scales on stem same color.
Ring lost – but there is a white flocculent band around stem. The
section gives idea of size, & the remarkable long extension below
the surface of the ground. I did not get the lower part but only the
part shown here. Found two specimens in low ground in woods. —
new to me. From your description (Lloyd – ph), take it as
L. acutesquamosa. Both specimens have the long root.
