NEW OR CRITICAL BRITISH FUNGI.

ago ; this species, however, has a pileus 8-9 in. across, and is a 
true Lepiota, having a persistent ring on the stem. A third 
species — Lepiota molybdites , Meyer — from Brazil also has green 
gills. To be consistent, a new family of the Agaricinese should 
be formed, which would naturally be called Chlorosporce, as truly 
green-spored species cannot with propriety be included in any 
recognized family. The small number of known species with 
green spores seems to stand in the way, yet if spore colour is 
admitted to be of fundamental value, it would appear to be the 
right thing to do. 
Agaricus (Tricholoma) amicus, Fries. 
Pileus 2-3 in. across, somewhat campanulate, then expanded, 
obtuse or slightly gibbous, very regular, even, glabrous, not viscid, 
pale brown, not becoming pale when old ; flesh thin except at the 
disc, rather soft, white, with a tinge of brown under the cuticle ; 
gills rounded behind, without a decurrent tooth, 4-5 lines broad, 
thin, distant, white, sides not veined, persistently white; spores 
elliptical, smooth, 6 x 4 p ; stem about 3 in. long, rather elastic, 
bulbous base up to 1 in. across, remainder cylindrical, equal, about 
half-inch thick, fibrously striate, solid, white.

Agaricus (Tricholoma) ionides, Bull. 
This very beautiful agaric has occurred in abundance among 
short grass in the arboretum, Kew Gardens, after the recent 
heavy rains. 
Agaricus (Clitocybe) molybdocephalus, Bull. 
Pileus 2J-4 in. across, campanulate and broadly gibbous, then 
expanded and the margin spreading ; smooth, even, grey, smoky 
grey, disc ochraceous-tan, becoming paler when dry ; flesh very 
thin except at the disc, soft, white when dry ; gills adnate and 
often with a minute decurrent tooth, rather crowded, more or less 
connected by veins, 5-8 lines broad, intermediate ones numerous, 
plane, margin quite entire, dingy horn-colour, then pallid ; spores 
colourless, globose, with a minute apiculus, 5 /x diameter ; stem 1^- 
5 in. long, up to § in. thick, solid, usually more or less narrowed 
towards the base, pallid, fibrillosely striate, minutely squamulose 
towards the apex.

molybdinus , Fries. Hym. Eur., p. 89. 
Csespitose or solitary. The present interesting addition to our 
flora answers admirably with the figure and description given by 
Bulliard, the only point of difference consisting in the somewhat 
shorter stem in the British specimen. 
On the ground amongst leaves, under beeches.
