CEYLON FUNGI. 
341 
The perithecia are not separate, as would be supposed from 
Cooke’s description, but totally immersed in a stroma. The 
stromata are elevated, covered at first by a thin lichen stroma, 
flattened pulvinate, irregularly circular, up to 2 mm. diameter, 
brownish-yellow or orange -yellow ; the surface is smooth, or 
broken and minutely granular, dotted with dark, scattered 
ostiola. The stromata are about 0.4 mm. thick, greenish- 
yellow internally when fresh, orange -yellow in dried specimens ; 
the context is rather loose and granular. The perithecia are 
in a single layer, somewhat distant from one another, and 
occupying nearly the entire thickness of the stroma ; they are 
black, oval, about 0*3 mm. high, 0*2 mm. diameter, with a 
conical ostiolum, which does not project. The asci are 
clavate, thick- walled towards the apex at first, 140-160 X 
12-14 pi. The abundant paraphyses are linear, branched 
above. The spores are fusoid, ends obtuse, greenish hyaline, 
thick-walled, 7-11-septate, 36-50 x 8-9 pi. 
Berkeley and Broome described this species in a footnote, 
a course which they also followed in the case of Platygrapha. 
It is evident that they considered these to be lichens, and, in 
fact, Trypethelium crocosarca B. & Br. is identical with part of 
the Ceylon specimen assigned by Leighton to Trypethelium 
Sprengelii Ach., 196 in Trans. Linn. Soc., XXVII., p. 185, 
It is Trypethelium, not ThyridaHa nor Melogramma. 
199.— -Piptostoma spilotum B. & Br. 
This species was described from Thwaites’ 348 as “ Minutum, 
planum, cito circumcissum ; ascis lanceolatis ; sporidiis 
oblongis curvulis. Sporidia *0025 (inches) long.” Saccardo, 
Sylloge, II., p. 813, places Piptostoma among the “ Genera 
dubia,” but in Sylloge, IX., p. 1054, it is included in Micro- 
thyriacese. 
There is apparently no specimen of Piptostoma spilotum at 
Kew, the British Museum, or Peradeniya. 
200. — Sordaria sarawacensis Ces. 
This species was collected by Beccari, and was recorded by 
Cesati as occurring in both Ceylon and Sarawak. His descrip- 
tion is “ Perithecia ex hyphasmate subie ulum sat tenax
