CEYLON FUNGI. 
345 
In the co-type in Herb. Peradeniya the perithecia are quite 
separate from one another, but crowded together on a 
slight basal layer of mycelium. They are conoid, 0-3 mm. 
diameter, apex papillate, pruinose, dark brown. The 
ostiolum is punctiform, and furnished with periphyses. The 
spores are elliptic to fusoid, ends obtuse, one-septate, not 
constricted, pale brown, with a striate, verrue ose ^wall, 
11-14 X 
The species is evidently Phæonectria, and will stand as 
Phæonectria umhrinella (B. & Br.). 
204. — Hypoxylon niphidium B. & Br. 
The original description of this species, in Fungi of Ceylon, 
1067, is “ Peritheciis prominulis in pulvinulos parvos aggre- 
gatis pulvere niveo conspersis ; sporidiis cymbiformibus 
hyalinis three-septatis (No. 1089). On bark. Sporidia *001 
long by -0003.” In Saccardo it was included under Melo- 
gramma. Berlese, in leones Fungorum, I., p. 50, stated that 
the original specimens were sterile. 
The co-type in Herb. Peradeniya bears mature stromata. 
They are superficial, circular, up to 4 mm. diameter, pulvinate 
or flattened pulvinate, minutely tomentose, with prominent 
ostiola, and apparently pale yellow. The tissue of the stroma 
is rather loose and white. The perithecia are situated at 
varying depths and have thick yellow walls ; the perithecial 
cavity is oval, about 0*35 X 0*25 mm., and the neck is 
up to 1*5 mm. long, totally immersed. The asci are 6-8 ^ in 
diameter, with uniseriate spores. The spores are hyaline, 
fusoid, spinulose, three-septate, slightly constricted, ends 
apiculate or rounded, 30-34 x 6-8 {jl ; sometimes one cell is 
inflated. 
The structure of the stroma is that, of Hyjpocrea. The 
spores resemble those of a Hypomyces, but are three -septate. 
The species agrees very well with Broomella, though the spores 
have only a short apiculus, not the long terminal filament 
figured by Broome for Broomella Vitalbæ (B. & Br.). It may 
therefore stand as Broomella niphidium. It is not, however, 
CO -generic with Broomella Ichnaspidis Zimm.
