CEYLON FUNGI. 49 



in having a membranous, glabrous pileus, and gills reticulated 

 behind : it agrees in being white, margin sulcate, stalk pul- 

 verulent and thickened below. 



3.— Lepiota oenopoda, B. & Br. 



Pileus at first acorn-shaped, then conico-canipanulate with 

 an abrupt prominent nipple-shaped umbo, finally plane with 

 the umbo arising perpendicularly, about 3 cm, in diameter, 

 white, umbo sometimes slightly brown, covered except the 

 umbo with minute white scales, silky beneath the scales or 

 when these have been washed off : margin strongly plicato- 

 striate, the plications extending half way to the umbo or 

 further : flesh thin. 



Stalk 4-6 cm. long, 3-6 mm. in diameter, attenuated up- 

 wards, sunk into the hollow umbo, white at first, then pinkish 

 with a powdery bloom, red when old, hollow, the cavity 

 lined with white shining fibrils, flesh pinkish. Ring white, 

 firm, movable, without free margin. 



Gills white, then pinkish, rather broad, somewhat distant, 

 equal, free, rising behind into the hollow umbo. 



Spores oval, somewhat pointed at one extremity, 7-10 

 X 4-6^. 



On the bark of living jak trees. 



The figure of Lepiota oenopoda shows an old specimen with 

 a red stalk and a partially collapsed, conico-campanulate 

 pileus : it is larger than any specimens recently collected. 

 Lepiota adorea, B. & Br., is a young specimen in which the 

 margin of the pileus is just separating from the stalk. Berke- 

 ley and Broome state that oenopoda grew on dead wood, and 

 adorea on the ground. They form one of Thwaites' gather- 

 ings, and were probably all collected at the same time : 

 undoubtedly both grew on wood. 



4.— Volvaria terastia, B. & Br. 



Pileus 11-20 cm. in diameter, broadly campanulate, then 

 almost plane, obtusely umbonate, viscid when first expanded ; 

 centre blackish brown with adpressed tomentum, elsewhere
