196. — Trematosphæria agnocystis (B. & Br.) Cooke. 
This was described by Berkeley and Broome as “ Sphæria 
(Pertusæ) agnocystis B. & Br. Innata, conica, coffeicolor, 
lævissima ; ostiolo papillæformi ; sporidiis biconicis, utrinque 
hyalinis. On dead wood.” In Saccardo, I., 722, it was listed 
as AmpJiisphærîa. Cooke, in Grevillea, XVI., p. 92, referred 
it to Trematosphæria, and gave the spore as three -septate, 
40 X 8 
The type specimens are on a decaying palm frond. The 
perithecia are scattered, conical, with a flat base, almost 
superficial, with the base slightly immersed, up to I mm. 
diameter and 0 ‘5 mm. high, with a thin purple-brown pruinose 
outer layer. The wall is black, carbonaceous, about 0 * 1 mm. 
thick. In some cases it bears a few scattered globose wart= 
like bodies, which are the immature perithecia of a parasitic 
Sphæria. The spores are pale brown, fusoid, three -septate, 
constricted at the median septum, ends obtuse, 33-39 X 5-6 
This species is very near Melanomma Vesuvius, but differs 
in the shape of the peri thee iuni and the smaller, non-inflated 
spores. It must stand as Melanomma agnocystis (B. & Br.). 
197. — Rosellinia plicatula (B. & Br.) Saec. 
This species was described by Berkeley and Broome as 
‘‘ Sphæria (Cæspitosæ) plicatula B. & Br. Fasciculato-con- 
gesta ; peritheciis atris collapsis minute granulatis plicato- 
rugosis ; sporidiis doliiformibus utrinque leviter attenuatis, 
nucleo magno (Nos. 39, 1069). On bark. Asci clavate, sporidia 
biseriate, *0006- ’0008 long by *0004— *0005 (inches). Very 
near Sphæria Pezizula B. & Rav., which has shorter hyaline 
sporidia.” In Saccardo, I., 261, it was included in Rosellinia. 
Thwaites’s 1069 shows superficial, irregularly circular, pul- 
vinate stromata, up to 2*5 mm. diameter and I mm. thick. 
They appear to bear circular, flattened, rugose, discoid peri- 
thecia up to 0*15 mm. diameter, but sections through the 
stroma disprove that interpretation. The substance of the 
stroma is pseudoparenchyma tons, and the perithecia are 
totally immersed ; they are narrow-oval, up to 200 jj. deep 
and 70 ^ dianxeter, with a thin hyaline wall. The superficial 
bodies are immature, but appear to be pycnidia ; they are oval
