The perithecia are superficial, scattered or clustered, up to 
0’4 mm. diameter, black, minutely rugose, with a small 
conical ostiolum. The asci measure 70-80 X 6-7 yi. The 
ascospores are elliptic, with rounded ends, 1-guttulate, pale 
blackish-brown, 8-11 X 3*5-4^. 
132. — Sphæria Janus B. & Br. 
This species was described by Berkeley and Broome in Fungi 
of Ceylon, 1105. The ascospores were said to be like those of 
Sphæria Bombarda. It was listed in Saccardo as Lasiosphæria. 
From the type specimen and recently collected examples 
it is found that the perithecia grow on dead wood, and are 
either scattered or clustered, black, leathery, superficial, with 
a slight basal weft of hyphæ, globose below, conical above, up 
to 0*6 mm. diameter, minutely rugose, longitudinally sulcate 
at the apex. When mounted the pierithecial wall is areolated 
with thinner pale brown lines, and the outer layer appears as 
a series of black polygonal areas united by hyphæ. The asci 
are cylindrico-clavate, with a long tapering pedicel, and 
8-spored ; they measure 250-350 X 12 The spores are 
at first hyaline, elliptic, about 20 X 12 with an apical 
appendage, up to 30 ^ long and 2 ^ diameter, and a basal 
appendage which consists of a thick part, 30-40 X 4 followed 
by a thinner part, up to 36 X 2 When mature the 
ascospores lose their appendages, and are black-brown, 
broadly oval, slightly attenuated at one end and truncate at 
the other, 17-22 X 10-12 pi The fungus is a Bombardia, and 
will stand as Bombardia Janus (B. & Br.). 
133. — Rosellinia Tetradeniæ (B. & Br.) Sacc. 
Sphæria (byssisedæ) Tetradeniæ was described by Berkeley 
and Broome in Fungi of Ceylon, 1094. No Thwaites number 
was quoted. It was included in Saccardo, Syll. Fungorum, I., 
p. 256, as Rosellinia, with the additional information, not in 
the original description, that it grew on branches. 
There is apparently no specimen of Rosellinia Tetradeniæ in 
Herb. Kew or Herb. British Museum. The description is 
“ Mycelio repente e fibris tenellis septatis ; peritheciis globosis 
subliberis ; ascis ovatis, brevibus ; sporidiis oblongo-ellipticis. 
On Tetradenia. Sporidia *0016 long.’'
