CEYLON FUNGI.

201. — Sphærella Rottleræ (B. & Br.) Sacc. 
Berkeley and Broome described this species as “ SpJiæria 
(Depazea) Rottleræ B. & Br. Epiphylla, e macula umbrina 
pallida oriunda, orbicularis, nivea, limitata ; peritheciis a tris.” 
It was said to occur on leaves of Rottlera quadricocca Boxb., 
evidently an error for Rottlera tetracocca Roxb., a plant now 
known as Mallotus albus Muell.-Arg. It was included in 
Saccardo, Sylloge, I., p. 536, as Sphærella Rottleræ. Cooke 
did not refer to it in his “ Sphærella and its allies ” (Jour. 
Bot., 1883). 
In the type specimen, Thwaites’s 1228 in Herb. Kew, the 
leaves bear circular, white spots, about 2*5 mm. diameter, 
surrounded by a broad, diffuse, purplish zone. The pycnidia 
are clustered in the centre of the spot, and are epiphyllous, 
subepidermal, black, about 0-15 mm. diameter. They do 
not contain asci, but oval, or subglobose, hyaline, continuous, 
obtuse pycnospores, 7-12 X 7-8 pi. 
As Berkeley and Broome did not record any measurement 
or description of the spores, it is uncertain whether the form 
described above is the species seen by them. It is quite 
possible that perithecia may occur on some of the spots. 
But as far as examination of the type shows, the fungus is a 
Phyllosticta and must be known as Phyllosticta Rottleræ 
(B & Br.)! 
The type in Herb. Kew is Thwaites’s 1228. Under 1142, 
Asterina nubecula B. & Br., in the Fungi of Ceylon, Berkeley 
and Broome noted : “ There is also a species on Rottlera tinctoria 
with depressed perithecia situated on snow-white spots, but 
unfortunately without fruit.” This description fits Thwaites’s 
1228. The leaf in Thw. 1228 is that of Mallotus albus (Rot- 
tlera tetracocca). 
202. — Sphæria (Depazea) Oxalidis Kirsch. 
Under this name Berkeley and Broome placed Thwaites’s 
486, in Fungi of Ceylon, 1122. It occurred on Oxalis corni- 
culata. They stated that the asci were broader at the base, 
37 '5 ^ long, 10 ^ broad, and the spores 10-12*5 ^ long, with 
from one to three nuclei. In Saccardo, I., p. 429, the Ceylon 
record was included under Læstadia Oxalidis (Rabh.) Sacc.
