52 FETCH : REVISIONS OF 



the colour and striate margin of the pileus, and the pointed 

 lower extremity of the volva, this appears to be an immature 

 specimen of the species which Berkeley and Broome referred 

 to Amanita vaginata. 



7.— Entoloma amethysteum (B. & Br.), Fetch. 



This fairly common species was sent to England by Gardner 

 (No. 31) and Thwaites (No. 203). Gardner's specimens were 

 named Tricholoma nudum, Bull. : Thwaites' were divided 

 into Tricholoma nudum, Bull., Clitocybe iopepla, B. & Br., and 

 Cliiocybe laccata, Scop., var. , amethystea, B. & Br. It occurs in 

 large numbers on rubbish heaps at Peradeniya during wet 

 weather, often densely csespitose. 



Pileus when young broadly conico-campanulate, margin 

 regular, incurved, becoming repand and irregularly lobed 

 when full grown, umbonate, smooth, margin striate when 

 moist, flesh thin : up to 9 cm. in diameter. 



Stalk up to 8 cm. long, 1 cm. in diameter, smooth, sometimes 

 split longitudinally and fibrUlose, tomentose at the base, 

 solid, equal or slightly attenuated upwards, often irregular. 



Gills narrow, rather crowded, attenuated outwards, sinuate, 

 edge irregularly lobed. 



Spores, pink, ovate or subglobose 5-6 x 3-4/^- 



The whole fungus, internally and externally, is at first 

 amethyst : in old specimens the centre of the pileus turns 

 brown, and the stalk is streaked with brown : the pileus 

 becomes -ashy-white when dried. 



Two of Berkeley and Broome's species, Tricholoma rubro- 

 cyaneum, B. & Br., and Tricholoma charisterum, B. & Br., 

 bear much resemblance to immature Entoloma amethysteum, 

 but in both cases the stalk is represented as white in the paint- 

 ings, and in this respect they differ from all the numerous 

 immature specimens of the latter which I have seen. 



8.— Flammula dilepis, B. & Br. 



This species is especially common on old coconut stumps. 

 The colour of the immature specimens differs completely from 

 that of the full-grown form, and, although the gills are yellow,
