494. Polyporus fuligo B. &. Br. (967). 
Type, Thwaites 967, in Herb. Kew, is marked “ cf. 
with 261.” It is on a palm, like P. Ravenalæ, but has 
much smaller pores, and tends to break up in dr 3 dng. 
It is apparently only a small-pored form of P. Rave- 
nalæ, — pores 50-80 ^ diameter, instead of 100-200 ^ as 
in the common form. Collected by von Höhnel at 
Peradeniya, and recorded by Bresadola (loc. cit.). 
495. Polyporus aneirinus Fr. (371). 
The Ceylon specimen, Thwaites 371, in Herb. Kew, 
is quite unidentifiable. It consists of five small patches, 
chiefly earth and sand, glued on paper. 
496. Polyporus Vaillantii Fr. (161). 
Thwaites 161 is represented in Herb. .Kew and 
Herb. Peradeniya. The Ceylon specimens have the 
habit of the European species, but have pores up to 
3 mm. long and O’ 1-0*2 mm. diameter, developed over 
nearly the whole surfare ; no cords of mycelium are 
evident, except those spreading from the margin of a 
patch. It is most probably not identical with the 
European species. As noted by Thwaites, it grows 
on the ground or on very rotten wood. 
497. Polyporus vaporarius Fr. (367, 369). 
498. Polyporus vulgaris Fr. (367, 369 in part). 
Thwaites 367 and 369 provided P. vajporarius Fr., 
P. vulgaris Fr., P. hydnophorus B. &. Br., and P. fulvus 
Fr. As is usual in such cases in Herb. Berkeley, the 
various species were not completely separated, especially 
in the duplicates, nor were the different Thwaites’ 
numbers kept distinct. The specimens included under 
P. fulvus Fr. at Kew are identical with those 
under P. hydnophorus B. & Br. ; this is a good 
species. 
Under P. vaporarius, in Herb. Kew, are Thwaites 133, 
and one piece marked 367, 369 ; there is also another 
piece, unnumbered, and a packet of duplicates. Under 
P. vulgaris, in Herb. Kew, are Thwaites 367, 369 
mixed, and Thwaites 369 separate. The “ vaporarius ”
