CEYLON FUNGI.

180. — Diatrype theloides B. & Br. 
This was described by Berkeley and Broome in Fungi of 
Ceylon, 1082, from Thwaites’s 543, as “ Pustula ta, ostiolis 
lævibus in disco parvo erumpente collectis ; sporidiis allan- 
toideis. Pustules closely adnate with the cuticle, which is 
blackened, sometimes merely lifting it up ; sporidia, *0003 
(inches) long.” 
The type specimen in Herb. Kew shows blackened oval 
areas, about 2 mm. diameter, slightly elevated, covered, 
except at the apex, by the radially ruptured epidermis ; other 
areas, not so definitely blackened and more widely split, show 
groups of projecting ostiola. The stroma is immersed in the 
bark, and is about 1*5 mm. diameter ; it consists of a group 
of oval, or globose, perithecia or pycnidia, 0*3-0 *4 mm. 
diameter. The pycnidia have stout, barely projecting 
ostiola ; the ostiola of the perithecia are produced into cylin- 
drical or clavate necks, up to 0 *5 mm. high and 120 ^ diameter, 
which converge to a common centre. Within the cortex 
above and below the fructification, and at a little distance from 
it, is a thin black layer, which encloses the perithecia or 
pycnidia and the cortical tissues in a Valsa -like lenticular 
stroma. This is more evident in the pycnidial stromata, 
over which it forms the blackened areas noted above. 
The wall of the perithecium is cellular and not carbonaceous. 
The pyc nospores are linear, straight or curved, 4-6 X 0*75 
hyaline. The asci are clavate, not long pedicelled, small, 
about 24 X 5 eight-spored. The spores are hyaline, 
cylindric, curved, 6-8 x 2 The fungus is apparently 
Valsa, and will stand as Valsa theloides (B. & Br.). 
181. — Diatrype chlorosarca B. & Br. 
Stromata erumpent, up to 2 mm. diameter, flattened 
pulvinate, almost plane, up to 0*8 mm. thick, minutely fur- 
furaceous becoming glabrous, rarely showing projecting 
perithecial elevations ; ostiola depressed, surrounded by a 
raised ring ; internally greenish -yellow, perithecial walls black, 
brown when mounted. Perithecia globose, 0*4 mm. diameter, 
or flask-shaped, up to 0*7 mm. high, 0*4 mm. diameter, 
6(14)17 (45)
