TEICHOLOMA. 



VI. Spongiosa. 



Pilens compact then spongy, obtuse, even, glabrous, moist 

 but not hygropbanous. 



Pirm, appearing in the autumn, in troops. Stem stout, 

 base usually incrassated, spongy-fibrous. GiUs at length 

 spuriously decurrent, but sinuate, a character by which the- 

 species are readily distinguished from Clitocyhe. 



* Gills not discoloured. 

 ** Gills discoloured. 



Gills readily separating from the pilaus in T. cinerascens and 

 some others. 



VII. Htgrophana. 



PUeus thin, somewhat umbonate, flesh at length soft,- 

 hygrophanous. 



Stem not rooting, containing a pith, entirely fibrillose. 

 Pileus unequally fleshy, hence more or less umbonate, very 

 thin towards the margin. Colour of the pileus, both when 

 moist and dry, very variable in the same species. Fleslx/ 

 moist, wateiy ; at first compact, then soft ; gills thin, not 

 broad. 



Pileus sometimes pulverulent, but this is abnormal, and 

 due to the persistence of the veil during dry weather. 

 Closely allied to the group Spongiosa, but tending towards- 

 Gollyhia rather than Clitocyhe. 



* GUIs whitish, not spotted. 



** Gills more or less violet, grey, or smoky. 



Series A. 



I. LIMACINA. 



* Gills not discoloured. 



Tricholoma equestre. Linn. 



Pileus 3-5 in. across, flesh thick, firm, white; convex- 

 then expanded, obtuse or sometimes more or less gibbons, 

 often wavy, discoid, viscid, squamulose, yellow usually with 

 a rufous tinge, disc darker, often greenish late in the season,
