=Pilosace=. Volva and ring both absent.

B. _Gills attached to stem._ (Quite free from stem in some species of _Coprinus_.)

+ _Stem with a distinct membranous ring._

=Stropharia=. Gills adnate dark brown or purplish.

=Anellaria=. Gills adnexed, grey and clouded with the black spores.

++ _Ring very imperfect or absent; gills decurrent._

=Gomphidius=. Gills subgelatinous.

+++ _Gills not decurrent, not adhering laterally when young, not deliquescent._

=Hypholoma=. Gills sinuate, dark brown or blackish-purple; veil often hanging in fragments from edge of pileus.

=Panaeolus=. Edge of pileus extending beyond the gills, pileus not striate.

=Psathyrella=. Pileus sulcate or striate.

=Psathyra=. Stem fragile; edge of pileus straight when young.

=Psilocybe=. Stem tough; edge of pileus incurved when young.

++++ _Gills adhering laterally when young, deliquescing at maturity._

=Coprinus=. Ring and volva present in some species, ring alone others, both absent in others; gills adnate, adnexed or free.

=Montagnites=. Volva present, buried in the ground.

CHITONIA, Fr.

=rubriceps=, Cke. and Ma.s.s. P. 2-3 cm. campan. then exp. umb.

reddish-brown; g. free, purplish-brown; s. 6-7 cm. hollow, paler than p., volva large, free edge torn; sp. 12 6.

Introduced along with living plants into Kew Gardens.

[=coprinus=, Fr. (= _Ag. involucratus_, Mont.) P. fleshy, convex, viscid, yellowish, sometimes floccosely scaly from fragments of volva; g. free, smoky-black; s. fistulose, naked, whitish, volva very small.

Unless the small volva is noticed, this fungus will be considered as a sp. of _Coprinus_.

AGARICUS, L.

A. EDULES. _Large, fleshy._

=augustus=, Fr. P. 8-14 cm. globose then exp. very obtuse, disc even, rest fibrillosely-scaly, pale yellow-brown; g. crowded, narrow, fuscous, remote from stem; s. 8-14 cm. solid, ring superior, large, areolately squamulose below; sp. 6 3.5. Edible.
