CEYLON FUNGI. 3 



Thwaites had only one specimen. But in Herb. Peradcniya 

 there is, in addition to the other half of the Kew specimen, 

 another complete example, as well as two specimens of 

 Trogia bicolor, all on the same sheet. It would appear that 

 Thwaites made two gatherings, the first consisting of one 

 example only, which he divided, while the second furnished 

 the specimens which were named Trogia bicolor. But he 

 considered them the same species, and placed them on the 

 same sheet in the Peradeniya herbarium. 



Of the specimens in Herb. Peradeniya, the half and one 

 other are dark brown, horny, and slightly translucent, with 

 a texture resembHng that of Stereum elegans ; they are 

 minutely striate. The other two specimens are smaller, less 

 widely expanded, light brown, and not notably horny ; the 

 pileus is striate, when examined with a lens. It would seem 

 probable that these are only younger specimens of Trogia 

 infundibuUformis . 



Trogia infundibuUformis, from fresh specimens, is entirely 

 pale purple, or pale purple-brown, up to 4 cm. high. The 

 pileus is deeply infundibuliform, about 3 cm. diameter, with 

 the margin lobed and decurved, thin, rigid, and somewhat 

 horny, minutely radially striate, with short broken strise, 

 becoming radially sulcate when dry. The gills are distant, 

 sometimes forked, up to 1 mm. broad, decurrent, with an 

 obtuse edge. The stalk is about 1*5 cm. high, and 2 mm. 

 diameter in the middle ; towards the base it expands, the base 

 being 4 mm. in diameter, and surrounded by a white fibrillose 

 ring, 1 • 5 mm. broad. The exterior of the stalk is pruinose, and 

 its wall is horny, like the pileus ; the interior is white, stuffed, 

 becoming hollow. The wall of the stalk is a continuation of 

 the pileus, and the hollow is filled with loose, white tissue, 

 which ascends for a short distance over the base of the funnel ; 

 the upper surface of the pileus is not continued across the top 

 of the stalk. There is consequently no true stalk. 



216. — Hydnum polymorphum B. & Br. 



Thwaites 178 was a Hydnum. Berkeley and Broome 



divided the specimen into two parts, one of which they 



named Hydnum (Apus) jiolymorphhim B. & Br., and the other 



Hydnum {Resupinati) versicolor B. & Br. The specimen was
