56 FETCH : KEVISIONS OF 



Spores purple-brown, ovate, with a large, blunt, sublateral 

 apiculus, 6-7 x 4yLt. 



Fairly common among grass at Peradeniya, but generally 

 solitar3^ 



Psalliota lasiophrys , B. & Br., is based on an old specimen of 

 this species, somewhat weather-worn. The original specimens 

 and paintings of both species have been examined. 



11.— Psalliota subseruginosa, B. & Br. 



Densely csespitose : pileus hemispherical, obtuse, 2'5-3 cm. 

 broad, or expanded, 4*5 cm. in diameter, sometimes slightly 

 umbonate, pale yellow, or with the centre dull dark green, 

 becoming pale green then yellow outwards : the greater part 

 of the pileus is always yellow : minutely tomentose, the outer 

 layer cracked into»'squarish areolae and showing paler yellow 

 or white between : margin somewhat incurved at first, 

 appendiculate. 



Gills for a long time white, then purple-brown, crowded, 

 free, attenuated behind. 



Stalk up to 9 cm. long, 2-6 mm. thick, equal, shining, 

 white, yellowish at the base, with a few loose fibrils, variously 

 twisted, becoming reddish when handled, stuffed then hollow. 

 The flesh of stalk and pileus titrns reddish when cut. Ring 

 near the top of the stem, Aisually directed upwards, lax, 

 persistent, white or yellow, for white with a yellow edge. 

 Spores pale purple-brown, oval, 5-6 x 3^^*. 



Berkeley incorrectly states that it is " viscidulo," and has 

 adnexed gills, and for this reason Saccardo lists it under 

 Stropharia. No specimens were sent to Berkeley, but 

 the figures (two sets) show free gills in each case, and 

 expanded, almost plane, pilei, with moderately long stalks. 

 Recent large gatherings show that the immature form 

 with long, drawn-up stalks is Berkeley's Lepiota macrocola. 

 Apparently Thwaites collected this with the specimens 

 which Berkeley called Psalliota, for he has marked it " ? var. 

 of 756." 



The figure of Lepiota macrocola shows three specimens out 

 of a dense cluster of twelve, the others being represented by
