the brown form is unpalatable.

=strangulata=, Fr. P. 8-10 cm. soon plane, livid-bay or grey, with
patches of the volva, margin striate; g. free, white; s. 10-14 cm.
stout, thinner upwards, pale, volva breaking up and forming 2-4
ring-like ridges on the stem; sp. 9-15 x 7.

Perhaps a vigorous form of _A. vaginata_.

[=urceolata=, Viv. P. thin, hemispher. then slightly depr. umb. viscid,

naked, volva urceolate.

with broad crowded warts or scales; g. free, white, edge darker,
crenulate; s. conical, everywhere floccosely scaly, white or greyish;
volva broken up into fragments; sp. glob. 11-12.

Differs from _A. vaginata_ in smaller size and imperfect volva.

[=praetoria=, Paul. P. thin, campan. then exp. naked, pectinately
sulcate, maroon or brownish; g. annulato-adnexed; s. ventricose, volva
large, lax.

=lenticularis=, Fr. P. 7-10 cm. globose, then convex, even, naked,
reddish-tan; g. free, crowded, pallid; s. 10-14 cm. subbulbous, white,
ring large; sp. ----.

[=Godeyi=, Gillet. P. pale honey-colour, naked, striate; g. free,

deciduous, darker wart-like squamules, near margin even and silky; g.
white; s. conical, base white-squamulose.

[=gemmata=, Paul. Exp. vermilion with angular warts; g. pure white; s.
solid, bulbous, whitish, no distinct volva.

=adnata=, W. G. Sm. P. 6-8 cm. yellowish-buff with patches of the volva;

&c.; g. free, white; s. solid, slightly thinner upwards, edge of volva

tinged brown; p. exp. glabrous, whitish, often with angular umber warts;
g. almost free, whitish; s. cylindr. whitish; sp. subg. 5-7.
