The perithecia are black, globose, 0*15-0*2 mm. diameter, 
minutely rugose, shining, with a minute conical ostiolum, at 
first covered with fragments of mycelium, becoming naked ; 
they are crowded, seated on, or partly embedded in, a thin 
purple-brown layer of mycelium. The asci are eight-spored, 
clavate, 90-100 X 10 The spores are cylindric with 
rounded ends, straight or variously curved, three -septate, 
very slightly constricted at the septa, 16-24 X 5 
The septa are scarcely visible, except under a high 
magnification. 
This is a Lasiosphæria, and will stand as Lasiosphæria 
regulina (B. & Br.). 
190. — Lasiosphæria acanthigera (B. & Br.). 
Sphæria {Villosæ) acanthigera B. & Br. was described as 
“ Peritheciis ovatis, sub lente pallide fuse is spinis brevibus 
latis concoloribus vestitis ; sporidiis linearibus curvis. On 
dung. The spines of this species are extremely curious, 
broad at the base, resembling in miniature those of a rose. 
The sporidia, when mature, are probably like those of S. 
hirsuta ; but in the specimens before us they are clearly young.” 
It was included in Saccardo, Sylloge, II., 198, under Lasio- 
sphæria. 
The only specimen in Herb. Kew is part of the type, ex 
Herb. Cooke. In Herb. Peradeniya this species is included 
with Sphæria nigrita, Thwaites 596. The specimens sub 
Lasiosphæria acanthigera in Herb. British Museum, ex Herb. 
Broome, are the conidial fungus, “ Thwaites 576, Dolos- 
bagey,” attributed by Berkeley and Broome to Xylaria 
tentaculata. 
The specimens in Herb. Peradeniya are more mature than 
those in Herb. Kew. The perithecia are ovate, or conical 
above, 0*4 mm. diameter, now black, minutely aculeate. 
The perithecial wall is cellular, and the outer cells are produced 
into short spines, which, as stated by Berkeley and Broome, 
resemble the prickles of a rose. These spines are- broadly 
conical below, with a narrow, conical, acute tip, which is 
curved or falcate ; they are 24-34 ^ broad at the base and 
28-34 [). high. The asci are eight-spored. The spores are at
