Pileus campanulate, then expanded, fibrillose, tawny, wholly clad 
with large, closely adpressed, darker scales (8-9 c.m. diam), stem 
solid, pale, fibrillose (8 c.m. long, 1-J c.m. thick), almost equal, 
flesh dirty whitish, darker at base and vertex ; gills broad, nearly 
straight (10-12 m.m.), rounded behind, adnexed, greyish, then

On the ground. Castle Howard. 
Xnocybe subrimosa, Karst. 
Pileus 2-3 c.m. across, conical, campanulate, then expanded, with 
a prominent conical umbo, margin often undulate, even, glabrous, 
the cuticle becoming broken up into longitudinal fibrils, then 
cracked, bay or pale rusty-ochraceous ; gills very much attenuated 
behind, free or slightly adnexed, rather ventricose, white, then pale 
tan, at length brownish ; basidia clavate, 30-42 x 14 /x ; cystidea 
fusoid, apex at first muriculate, 65-95 x 14-20 /x ; spores subglo- 
bose, unequally stellately spiny, pale yellowish, 13-14 x 10-11 /x

Clypeus subrimosus, Karsten Meddl. ad Soc. pro Fauna et Flora 
Fennica, 1888-1891, p. 38 ; Coolce Illus. pi. 402 (called Inocybe scabella). 
Amongst grass. 
Flesh white, inodorous and insipid. 
Entoloma Cookei, Ch. Rich. Descr. et dess. p. 559, t. 3, / 10-11. 
Agar (Plutens) phlebophorus, Ditm., var. reticnlatus, Cooke Kdbk. p. 
118, Cooke Illus. pi. 422 b. 
The variety of P. phlebophora described by Cooke certainly has 
adnexed gills, and cannot therefore be a Pluteus , notwithstanding 
the fact that it grows on wood, and must henceforth be known as 
Pntoloma Cookei ; a species readily distinguished by having the 
pileus, 1-2 in. across, of a salmon colour or reddish-orange, and 
ornamented with pale raised ribs, anastomosing to form a network ; 
stem about lin. long ; spores globose, minutely echinulate, 8 /x 
diam., cystidia absent.
