453. Polyporus appendiculatus B. &. Br. 
Thwaites’ specimen at Kew consists of fragments 
only ; it appears identical with the Ceylon species 
assigned to P. sulpJiureus and P. lacteus. 
454. Polyporus dissitus B. & Br. (966). 
Part of Thwaites 966 is in Herb. Kew, and the 
remainder in Herb. Peradeniya. In each case the 
specimen is almost entirely resupinate with a slightly 
reflexed margin. Bresadola has appended to the Kew 
specimen the following note : — “ Forma resupinata 
juvenilis Polypori adusti Fr. Structura quoque iden- 
tica.” The fresh specimens, however, do not resemble 
Polyporus adustus. This species is, in my opinion, 
identical with Polyporus secernibilis Berk., but not 
with the Ceylon specimens assigned by Lloyd to P. 
secernibilis. 
455. Polyporus polytropus B. & Br. (604). 
Two specimens from Thwaites 604 are in Herb. 
Peradeniya, and the remainder in Herb. Kew, part 
under P. polytropus and part under P. bicolor Jungh. 
All the specimens are the same species. A note by 
Bresadola on the type specimen in Herb. Kew reads 
“ P. polytropus B. & Br. = P. pruinatus K., 1833 = P. 
anisopilus Lév., 1843 = P. anebus Berk., 1847.” 
456. Polyporus kermes (970). 
The type in Herb. Kew contains three specimens 
without any Thwaites’ number. The specimen returned 
to Ceylon under Thwaites 970 is not P. kermes, but 
Pomes dochmius. In the type specimen of P. kermes 
the upper surface is hard and concentrically zoned. 
Specimens recently collected in Ceylon are soft and 
spongy when fresh, almost completely resupinate, 
with a narrow free margin ; but when dry the fungus 
contracts and the upper surface becomes hard. Judged 
by these recent specimens the apparently free upper 
surface of the type specimens was, when growing, 
closely applied to the substratum. P. kermes, from 
the fresh specimens, is a Polyporus, not a Fomes. To
