is H. discopoda. There is also another specimen, no 
date or number, originally about 6 inches in diameter, 
half from Herb. Cooke and half from Herb. Berkeley ; 
my notes on this example have been mislaid. 
524. Hexagonia durissima B. & Br. 
— Hexagonia sulcata Berk. 
This species was described from Gardner’s collection, 
and is probably the same as Hexagonia durissima. 
Lloyd {loc. cit.) states : ‘‘ This strongly-marked species 
is only known from Ceylon. Berkeley published it in 
1847 with a good figure, and sent specimens to both 
Fries and Montagne. That sent to Montagne was 
t5rpically sulcate, but the specimen to Fries was more 
even. Berkeley did not retain a specimen in his own 
herbarium, and when some twenty years later he 
received the smooth form also from Ceylon he described 
it as Hexagonia durissima. It is the same as the 
specimen of sulcata he sent Fries. Whether or not it is 
the same species as sulcata I do not know, but I think 
it probably only a smooth form.” 
Hexagonia durissima is represented in Herb. Kew 
and Herb. Peradeniya. Though there is now no 
specimen of H. sulcata in ^ Herb. Kew, it is clear that 
Berkeley retained one for some time, for there is a 
specimen in the British Museum which he gave to 
Phillips. 
525. Hexagonia adnata B. & Br. (610). 
The type in Herb. Kew is merely a fragment in a 
* much damaged condition, and hardly warranted a 
name. It was a large-pored, thick species. Lloyd 
{loc. cit.) regards it as an anomaly of some kind. 
526. Hexagonia pergamenea B. & Br. 
Fide Lloyd, this is a species close to Polystictus 
dermatodes. In my notes I find that I have put it down 
as T. dermatodes, but now think that that determination 
-- may be erroneous. It requires comparison with 
- - - Polyporus zeylanicus Berk, A specimen forwarded to 
me from Annam, determined by Graff as Polystictus
