Plants unbranched, tufted, very brittle, 4-8 cm. high; smell 

 none; taste marked, pleasant. Clubs white when 5^oung, 

 later pale mouse-grey, tips brown, base whitish, cylindrical 

 or clavate, sometimes furrowed, surface smooth or slightly 

 furrowed, becoming hollow with age, apex blunt or acute. 

 Stem not at all or scarcely distinct from club. Flesh white, 

 the hymenial layer easily peeling off. Internal structure of 

 short cylindrical cells, 30-50 x 10-15 /a, parallel to the long 

 axis of the club; structure in transverse section pseudo- 

 parenchymatous, like that of C. vermicularis. Basidia incon- 

 spicuous, 35 X 6-7 /x; sterigmata 2-4, short. Spores smooth, 

 hyaline, cylindric-ellipsoid or somewhat pip-shaped with 

 minute oblique apiculus, 6-8 x 3-4JU., contents often guttulate 

 or granular. 



Habitat. Amongst grass in fields. Not common. 



This species has the dense tufted habit of C. vermicularis and 

 occurs in similar situations, but is grey in colour. If there is 

 any doubt the much larger spores at once distinguish it.

Plants simple or very rarely branched, densely tufted, 

 connate at the base, 5-8 cm. high, clear canary-yellow; smell 

 none when fresh, taste bitter. Clubs elongated, spindle- 

 shaped, tips acute, often becoming hollow and compressed. 

 Stem not distinct. Flesh whitish, as in C. inaequalis. 

 Internal structure of fine filaments, 4-6yu, thick, more or less 

 interwoven, walls sometimes rough; occasional hyphae with 

 dark yellow contents. Mature basidia hyaline, 35-40 x 6-8/u.; 

 sterigmata 4, slightly curved. Spores globose, smooth, minutely 

 apiculate, 5-7 (-8) ^ in diameter, at first yellow, then colourless. 



Habitat. Amongst grass in the open and in woods. Common. 



Known amongst the simple yellow species by the densely 

 tufted habit, the canary-yellow colour and the bitter taste.
