IV. Volva and ring absent. Veil very evident--at least in a young state--as a felty coating, which breaks up during expansion of the pileus into patches, cottony, squamulose, fibrillose or mealy. Not glistening nor micaceous. p. 231.

V. Volva and ring absent. Pileus covered with glistening micaceous particles when young. p. 236.

I. Volva distinct, with a free margin; ring present or absent.

* Large; pileus more than 2 cm. high and wide.

+ Stem white.

=sterquilinus=, Fr. P. 5-7 cm. high, coarsely sulcate, silvery grey, disc tawny with squarrose squamules; g. free; s. 9-15 cm. white, dark when bruised; volva with free margin, sometimes a ring on stem; sp. 18-20 x 11-12.
