164. — Psalliota erythrospila B. & Br. 
Pileus up to 1*5 cm. diameter, hemispherical, convex or 
conico-convex, or almost plane, purple -red, the cuticle broken 
into minute scales ; margin at first appendiculate. Stalk up 
to 3 cm. high, 1*5 mm. diameter, white, equal, minutely 
tomentose ; ring ascending, white, upper edge purple-red. 
Gills ventricose, rather crowded, free, but close to the stem, 
white, then purple-brown. Spores purple-brown in mass, 
almost hyaline by transmitted light, oval, 6 x 4 pi. 
In Ann. Perad., IV., p. 55, this species was referred to 
Lepiota earochroa B. & Br. That has proved to be incorrect. 
165. — Psalliota arginea B. & Br. 
Pileus broadly conico-campanulate, obtusely umbonate, 
up to 1 cm. diameter, white or grayish -white, the umbo 
becoming pinkish -red, membranous, radially silky striate. 
Stalk up to 2 cm. long, 1 mm. diameter, often flexuose, white, 
shining, powdered, stuffed ; ring small, spreading, persistent. 
Gills pinkish, then pale brown, ventricose, free. Spores pale 
purple-brown in mass, oval, slightly inequilateral, 4 x 2*5 pi. 
On bare ground, Peradeniya. 
166. — Psalliota microcosmus B. & Br. 
Gregarious ; pileus conical, then conico-campanulate, ob- 
tusely umbonate, up to 4 mm. diameter, white, silky with 
short adpressed fibrils ; flesh white, comparatively thick over 
the stalk. Stalk up to 1*3 cm. high, 1 mm. diameter, white, 
minutely fibrillose ; ring near the apex, spreading horizontally, 
rigid ; apex of stem silky striate. Gills pallid, then pale 
purple-brown, crowded, free, but close to the stem, ventricose. 
Spores pale purple-brown, oval, 5 X 2*5 
On bare ground, Peradeniya, with Ps. arginea ; a stouter 
species than the latter, not striate, but perhaps only a smaller, 
more compact form of it. Stains the paper purple when 
pressed. 
167. — Psathyra obtusata Fr. 
Berkeley and Broome recorded, as Psathyra obtusata Fr., 
Thwaites’s 711*, 712, 829, cum iconibus, and as Psathyra
