REVISIONS OF CEYLON FUNGI. 385 



justified by the Ceylon examples : it would stand almost as 

 well in Hiatula as in Lepiota, though there are so many Ceylon 

 species which link the two genera that a distinct Une can 

 hardly be drawn. 



The descriptions in Massee, British Fungus Flora, state that 

 the flesh is thin, the margin semi-transparent, gills whitish with 

 a yellow tinge ; whole plant white, sulphur yellow or yellow ; 

 disc often brownish ; spores elUptic, 7-8 X 4 /i. 



But the above views of what constitutes Sowerby's Agaricus 

 cepcBstipes are apparently not held in all quarters. F. S. 

 Earle, in BuU. New York Bot. Gard., V., No. 18, p. 448, 

 proposes a new genus, Mastocephalus, taking as the type 

 L. cepcBStipes (Sow.), and gives as characters of the genus, 

 " Pileus fleshy, stipe peronate." But the pileus of L. 

 cepcBstipes, as understood in Ceylon, and apparently also in 

 Europe, is certainly not fleshy, but rather membranous ; and 

 the stalk is mealy, but not peronate. If Lepiota cepcestipes 

 is removed from the genus Lepiota, it can only be transferred 

 to Hiatula.

 No. 20, Journ. Linn. Soc, XI., p. 500. 



Pileus 2*5 to 3 cm. diameter, plane, or repand, radially 

 pHcato-sulcate almost to the centre, which consists of a shghtly 

 convex disc 3 to 5 mm. diameter : disc pale brown or greenish- 

 yellow, smooth ; crests of the ridges clothed Avith sulphur- 

 yellow or greenish-yellow flocci ; between the ridges, hyaline, 

 somewhat transversely wrinkled ; flesh none except in the 

 central disc. 



Stalk 6 to 9 cms. high, attenuated upwards, about 2 mm. 

 diameter at the base, 1 mm. diameter at the apex, very pale 

 greenish-yellow with a few flocci, or white and almost glabrous, 

 sunk into the central disc, hollow, white internally ; ring 

 about two -thirds the length of thefstalk from the base, small, 

 evanescent, yellowish. 



GiUs white, transparent, narrow, equal, nearly all reaching 

 and attached to the central yellow disc surrounding the apex 

 of the stalk. Spores broadly oval with an obtuse papilla at
