squamules ; white. V. free from the stem, except at the 
base, sheathing, fragile, almost completely buried in the 
ground, brownish. Very common amongst grass in woods 
and by roadsides, etc., from June to Nov. Usually solitary. 
Persoon divided vaginata into two distinct species: the 
grey form ( livida ), and the brown one ( spadicea ). One 
appears earlier in the season than the other. Dr. Plow- 
right remarks {Brit. My col. Soc. Trans., vol. i., p. 40) that, 
in addition to the above differences, “ in the reddish-brown 
form {spadicea) there is a second volva inside the outer; in 
the grey form {livida) there are folds or wrinkles of con¬ 
siderable size in the inner surface of the volva.” There is 
also a pure white form, Greville’s Agaricus nivalis.
