Thwaites 605 ex Herb. Currey and Herb. Cooke ; these 
are chiefly resupinate, but show a marginal dimidiate 
portion. These latter are identical with the part 
marked “ P. zonalis resupinate ” by Bresadola, and 
with the specimens of P. cartilagineus, sub P. zonalis 
and P. cartilagineus. 
Another part of Thwaites 605 is included in Herb. 
Kew under P. dochmius. It contains a resupinate 
piece, matching Bresadola ’s “ P. zonalis resupinate ” 
sub P. epilinteus ; and a specimen said to be young P. 
dochmius. The latter resembles P. dochmius to some 
extent, but is thinner, and appears to have been some- 
what cartilaginous. I have not seen young P. doch- 
mius in this form. This part of Thwaites 605 originally 
contained P. siennæcolor also, but the specimen of the 
latter was removed by Cooke to another cover. 
The part of Thwaites 605 in Herb. Peradeniya con- 
tains one specimen of Polyporus durus, three specimens 
of the form assigned to immature P. dochmius, and one 
specimen of “ P. zonalis resupinate.” 
Thwaites 605 therefore consisted of — 
(1) Polyporus durus. 
(2) Polyporus zonalis. 
(3) A species assumed. to be young F . dochmius. 
(4) A species named P. cartilagineus in its dimidiate 
form, and P. epilinteus in its resupinate form. 
(5) P. siennæcolor. 
The determination of (3) as P. dochmius appears 
doubtful ; no form matching this has been collected 
recently. According to Bresadola’s determination, 
(4) is Polyporus zonalis ; petaloid forms of P. zonalis 
are not uncommon, though not so markedly pseudo- 
stalked as in P. cartilagineus. But Bresadola’s deter- 
mination of P. epilinteus, as resupinate zonalis, appears 
to be correct, and hence P. cartilagineus is P. zonalis.
