Cooke (Journal of Botany, XXI., p. 109) listed “ Sphærella 
Oxalidis Kirsch, in Lotos, 1856, 203 ; Berkeley and Br., Ceylon 
Fungi, 1122,” and added : “ This is referred to Læstadia 
Oxalidis (1635) by Saccardo ; but it is quite a different species, 
as will be evident from a comparison of the diagnosis in 
Lotos, and the description 1635. It approaches more closely 
to Sphærella depazeæformis, 1984. Whether all these may be 
forms of one species may be matter of opinion.” 
The Ceylon fungus produces membranous, circular, brown- 
ish-white spots, up to 2 mm. diameter. The perithecia are 
clustered in the centre of the spot, amphigenous, usually 
hypophyllous, black, about 75 ^ diameter, sub-epidermal, 
prominent. The asci are oval, or oblong-oval, sometimes 
attenuated upwards, with a short pedicel, 30-36 x 8 The 
spores are biseriate, narrow-oval or subcymbiform, straight 
or sometimes curved, one-septate, not constricted, hyaline, 
10-11 X 2*5 It is certainly a Sphærella. 
Læstadia Oxalidis (Rabh.) Sacc. is said to have asci 32-36 
X 8 sessile, lanceolate ; spores fusiform, ventricose, 14 x 
4 [K. Sphærella depazeæformis (Auersw.) Ces. et de Not. has 
perithecia 40-46 diameter ; asci ovate, attenuated below, 
34-36 X 8 ^ ; and spores fusiform-oblong, straight, one- 
septate, 8-10 X 2-3 [L. 
From the dimensions of the spores it would appear that the 
Ceylon species is near Sphærella depazeæformis, though the 
shape of the spores appears to be different. The shape of the 
ascus agrees with that described for Læstadia Oxalidis. It 
would seem possible, however, that these two species are the 
same, as Cooke suggested. I have not been able to consult 
the original description of Sphærella Oxalidis Kirsch. 
203.— -Hypoxylon umbrinellum B. & Br. 
This was described in Fungi of Ceylon, 1075, as “ Late 
effusum ; peritheciis minutis ovatis metulæformibusque umbri- 
nellis materie furfuracea vestitis ; ascis linearibus ; sporis 
subellipticis, uniseptatis, demum echinulatis (1111). On dead 
wood with Byssisedæ. Margin of the stroma often barren, as 
in H . ruhiginosum ; *0005 by *00025.” In Saccardo, 
I., p. 729, it was listed, with a query, as Amphisphæria.
