convexo-expanso, dein late umbonato, carne alba; lamellis stipite 
adnexis, sinuatis, ventricosis, cinereis dein cinnamomeo-brunneis, acie

In sand dunes or sandy places. Type specimens no. 22106, Herb. 
Cornell University, in sand dunes, Grand Haven, Mich., Sept. 23, 
1907, W. T. Wallace, collector. In these specimens the pileus is pale 
ochre, and the stem white, becoming tinged with the color of the pileus. 
No. 18494, in sand, Sodus Point, Wayne Co., N. Y., B. C. WiUiams, 
collector (reed. Nov. 2, 1903); the pileus is wood-brown on the umbo, 
yellowish toward the margin, the margin in some splitting deeply. 
No. 24209, in sandy ground. Six Mile Creek, near Ithaca, N. Y., 
July 17, 1917, J. H. FauU, collector. These specimens are much smaller 
and the pileus walnut-brown to burnt umber (R. 1912). In nos. 
18494 ^i^d 22106, the mycelium binds the sand into a large ball; the 
ball of sand in no. 24209 is much smaller, perhaps because the plants 
are much smaller. 
This species is related to Inocybe bulbosa Pk. but differs in the 
character of the spores, cystidia, and bulb.
