132 AGARICACEÆ Inocybe
Gills usually sinuate, sometimes adnexed, adnate or decurrent,
adhering to the hymenophore, except 602 and 621, at first pale,
changing colour, but not to fuscous-ferruginous. Spores often
angular; pale dull tan, brownish or brown. (F'g- 34-)
All the species, except 644, grow on the ground ; they are
somewhat small ; none are edible, and the majority have a somewhat
nauseous odour.
Inocybe as defined by Fries {Hymenomycetes Europmi, p. 226) has
no genus corresponding wholly with it in structure amongst the
white-, pink-, purple- or black-spored groups. Certain of the fibrous-
pileated species of Tricholoma, Entoloma and Stropharia might,
however, be separated as analogues. Inocybe was formerly included
in the next genus, Hebeloma. Species 598—646
Mr. George Massee, in his monograph of the genus (Annals
of Botany, XVIII. ( 1904), p. 459), has rearranged the species in two
groups, viz. : I. Spores rough, and II. Spores smooth ; these groups he
has again divided into—A. Cystidia present, and B. Cystidia absent,
with minor distinctions as to a whitish or coloured stem and brownish
or olive-tinted gills.
a. Squarroses. Pileus squarrose, somewhat fuscous. Stem scaly,
smooth above, same colour as pileus, solid except 204.
598—607
b. lacerm. Pileus torn into scales or fibres, not split into
cracks. Stem fibrillose, paler than the pileus. 608—619
c. Rimosa:. Pileus longitudinally fibrous, soon cracked, partially
adpressed-scaly. Stem fibrillose, whitish, slightly tinged
with the colour of the pileus. Many become yellow when
old. 620—634
d. Velutince. Pileus not cracked, the cuticle fibrilloso-woven,
becoming even or adpressedly-scaly. Stem shining, smooth,
whitish, mealy above. 635—642
e. Viscidce. Pileus viscid, even. 643—646
a. Squarrosce.
