1911] Davis, — Fleshy Fungi of Stow, Massachusetts 61 
At first sight it reminded me of Amanitopsis strangulata (Fr.) Roze 
in color and size of pileus, and of Lepiota procera Scop. in annulus 
and stem. I quote the following description from Worthington G. 
Smith’s “Synopsis of the British Basidiomycetes,” p. 16: “A. 
cariosa Gill. (from the carious stem). P. soft, even, brown, whitish- 
brown, or dark-grey, unequally clad with thin, nearly white patches 
and clouds. St. fragile, somewhat enlarged below, white, pale umber 
and brown, scaly at base. G. adnate then seceding and free. Sus- 
pected poisonous. Woods. Sept. 4% 5%x8'. Closely allied to 
A. spissa Opiz.” 
The annulus of my plant was fixed, thin and dry. The exact 
description of my plant was drawn from the fresh specimen by Mr. 
L. C. C. Krieger of Cambridge, Mass., who determined the species. 
Mr. Krieger’s notes are as follows: “Collected by Mr. Simon Davis in 
Stow, Massachusetts, August 25, 1910, in a tamarack swamp, at the 
foot of a maple. 
Pileus 8 cm. broad, explanate, elevated at the very dark brown 
disk, paler toward the margin, moist and oily to the touch, smooth 
but covered with numerous, rather flat, grayish or light brownish 
woolly warts. The margin non-striate or very indistinctly short- 
striate. Flesh thick at the disk, thinning out toward the margin, 
dark brownish and watery. 
Lamellae rather broad (9 mm.), tapering toward the stem, attached, 
moderately close, irregularly dimidiate, somewhat eroded on their 
edges, whitish when fresh, later on buff-colored and watery, becoming 
almost fluid and (on the application of moderate artificial heat) 
drying with excessive slowness into an agglutinated dark mass. 
Stem 11 cm. long, terete, 1.9 cm. thick at the abruptly terminating, 
non-bulbous base, tapering toward the apex to a diameter of 9 mm.; 
pale dirty brown, almost white above, darker and more reddish 
brown below. The surface below the annulus covered with brown, 
downward-pointing and very loosely attached fibrillose squamules 
which are more conspicuous near the base; the surface above the 
annulus marked with horizontal zigzag broadish lines, indicating a 
rupture of the cortex. The very base of a brown ochre color, appar- 
ently stuffed, becoming hollow. Flesh watery, flaccid. 
Annulus superior, cream-colored, medium size, spreading; margin 
frayed. 
Volva absent at the base of the stem but present on the surface of 
the pileus, as described above.
