CEYLON FUNGI. 9 



yellow-brown, with granular contents, and filled with large 

 brown granules when old, not septate, exparded at the axils. 

 The sporangia, or asci, are oval, hyaline or pale yellowish, 

 becoming pale yellow-brown, thick-waL'ed, with granular 

 contents, terminal, 90-120 X 64-80 (x. Thwaites's specimen 

 agrees completely with this. It appears to be undoubtedly 

 Endogone. 



The specimen of Endogone fragilis in Herb. Peradeniya 

 (Thwaites 964) is a fragment only. The denser outer layer, if 

 ever present, has been broken off, and it is now a small 

 crumbling mass, about 4 mm. in diameter. Its asci are 

 chiefly subglobose, 50-64 X 48-55 [i., with some oval, 50-80 \k 

 long, and its hyphae are only up to 10 li. diameter. It is certainly 

 Endogone, and probably only a young state of Endogone Julva 



220.— Broomella niphidium (B. & Br.) Cooke. 



This species, re-described in Ann. Perad., VI., p. 345, waa 

 transferred to Broomella by Cooke inGrevillea, XII., p. 105. 

 This had been overlooked, probably because, by a printer's 

 error, the name is there given as Broomella nephidium. 



221. — Rhytisma maculosum B. & Br. 



This was described by Berkeley and Broome from Thwaites 

 426, on leaves of Sterculia (Pterygota) alata, and Thwaites 497, 

 on leaves of Cansjera Rheedii. Both collections are represented 

 in Herb. Kew and Herb. Peradeniya. A few lines later they 

 described Rhytisma Pterygotse, on leaves of Pterygota alata, 

 Peradeniya, April, 1866. Both these were transferred to 

 Marchalia by Saccardo. 



The Kew specimens of these two species have been examined 

 by von Hohnel, who found that Thwaites 426 was identical 

 with the specimen gathered in April, 1866 (IMitt. IX., pp. 48, 

 49 ; X., p. 37). He established on it a new genus, Dothidas- 

 teroma, with the single species Dothidasteroma Pterygotae, 

 subsequently changed, when the identity of the two species 

 was discovered, to Dothidasteroma maculosum. Von Hohnel's 

 genus is accepted by Theissen and Sydow in their revision of 

 the Dothideales, Ann. Myc, XIII. (1915). The host plant is 

 Sterculia Thwaitesii Mast.
