PETCH : 
internally, stuffed, base slightly tomentose with white tomen- 
tum. Gills pink, ventricose, broad (4 mm.), rather distant, 
free. Spores pink, narrow-oval, 7-9 X 4 
On wood, Peradeniya. 
152. — Pluteus glyphidatus B. & Br. 
Pileus campanulate, obtuse, then expanded, umbonate, 
up to 5 cm. diameter, lemon-yellow, thickly covered with 
minute ashy, or gray, close-set warts or points, or streaked 
with ashy fibrils, centre remaining yellow, the remainder 
becoming pinkish ; margin striate ; flesh thin, white. Stalk 
up to 6 cm. high, 4 mm. diameter, pale yellow or white, equal 
or slightly attenuated upwards, glabrous, sometimes powdered, 
tomentose at the base, solid. Gills yellowish, then pink, free, 
distant, edge minutely serrate, broadly ventricose or equal, 
rounded at both ends. Spores Indian red in mass, globose, 
5-7 ^ diameter. 
On decaying palm fronds, Peradeniya. A form occurs 
without any trace of yellow. 
153. — Pluteus escharites B. & Br. 
Pileus up to 3*5 cm. diameter, centre depressed, black- 
brown in the centre, the cuticle elsewhere broken into minute 
black-brown scales, arranged somewhat radially, so that the 
pileus is feebly radially streaked. Ground colour between 
the scales pallid, then pinkish. Stalk white or pallid, sub- 
translucent, up to 3*5 cm. high, 3 mm. diameter, equal or 
slightly expanded upwards, stuffed, then hollow, glabrous 
above, with a few fibrils below, which turn blackish when 
handled, or mealy with minute black granules, base slightly 
white tomentose, often swollen. Gills free, ventricose, 
rounded at both ends, white, then pink. Spores globose, 
5-7 or broadly oval, 5x7^, pink, smooth. Cystidia 
flask-shaped, up to 20 ^ high, 16 [jl diameter below, 6 ^ above, 
scanty. 
Massee (Grevillea, XXI., pp. 77-82) states that the spores 
are elliptic fusiform, very minutely warted, 10 X 6 pi, and 
that cystidia are absent. The co-type in Herb. Peradeniya 
has globose spores 5-7 and flask-shaped cystidia on the
