CEYLON POLY PORI. 
103 
duplicates, already referred to, are identical with one 
specimen on the sheet of P, vulgaris, Thwaites 369. 
In Herb. Peradeniya is a sheet marked “ 367 and 
369,” which bears sixteen pieces ; nine of these are 
P. hydnophorus, four are “ P. vulgaris,'^ and three are 
“ P. vaporarius.” Another sheet marked “ 367, 369 ” 
bears three pieces of “ P. vulgaris P 
Neither of these names appears to be correctly 
applied. The species assigned to P. vulgaris is identical 
with that named P. interruptus B. & Br., the latter 
being, in Herb. Kew, a younger stage ; it is a pinkish- 
white species, with rigid, thin dissepiments (when fresh). 
The species assigned to P. vaporarius is white, but 
stout, with pores up to 5 mm. deep, and thick, rather 
soft dissepiments (when fresh). 
499. Polyporus callosus Fr. (370). 
In Herb. Kew, Thwaites 370 consists of four pieces 
on one sheet, and a single piece on another sheet which 
seems different ; there is also a piece marked 367, 
P. callosus. 
In Herb. Peradeniya the sheet marked 370 bears 
five pieces, probably all P. callosus, and two pieces of 
another species. Another sheet marked 968, which 
should be Trametes versiformis, bears three pieces of 
P. callosus, and one of P. niphodes. 
Probably not P. callosus, but I have not met with it, 
and do not know it in the fresh state. It is thin, with 
extensive glabrous patches on which the pores are 
barely developed. 
500. Polyporus vinctus Berk. (208). 
Thwaites 208 in Herb. Kew is identical with the 
species which we have for some years been naming 
Poria hypolateritia in Ceylon. It is, I beheve, 
identical with the type specimen of Pona hypolateritia 
Berk, from the Nilgiris, the latter being young and 
poorly developed. Thwaites 208 in Herb. Peradeniya 
is a different species ; it resembles P. hypolateritia 
superficially, but the basal layer is brown.
