 Stipe thick, stout, with a short root, floccose-scaly, yellowish ; 

 the annulus membranaceous, persistent. Lamellae rather broad,

 long, 5-9 X 3-5 mic. 



Growing on the ground ; Ohio, M. E. Hard. Pileus 6-9 cm. 

 in diameter; stipe 10 cm. high, 10-15 mm. thick. 



II. OCREATAE. The Hhrillae of the surface of the pileus

Pileus fleshy, ovoid then convex and expanded, obtuse or 

 subumbonate; the flesh thin, white, fragile; the dermis radiately 

 fibrillouse, its surface at first densely scaly-squarrose, the brown 

 or blackish tufts soon disappear, leaving a smooth umber cor- 

 tex, paler toward the margin. Stipe tapering upward from a 

 solid base, hollow above, below the annulus clothed with brown 

 squarrose scales, above white-mealy ; annulus membranaceous, 

 persistent, whitish with a brown border. Lamellae rather broad, 

 ventricose, at first argillaceous, at length pale umber ; spores pur-
