DECADES OF FUNGI. 337 
20. Doth. appendiculosa, Mont. and Berk. stromate sub- 
orbieulari plano epiphyllo fusco opaco ambitu breviter et 
minutissime fimbriato; cellulis hemisphericis prominulis ; 
ascis brevibus; sporidiis oblongo-ellipticis basi appendi- 
culatis fuscis, sursum circumscissis. (Tas. XV. A.) 
On living leaves. Java. Zollinger, n. 803. 
Forming epiphyllous, scattered, suborbicular, opake, brown, 
flat spots about half a line broad, mixed with smaller spots, 
which contain a single cell only. Border shortly, but very 
distinctly fringed under the microscope. Cells hemispherical, 
for the most part projecting above the surface of the stroma, 
which is quite superficial, indistinctly perforated. Asci short, 
obtuse, containing eight brown oblong elliptic sporidia, fur- 
nished at the base with a little colourless papilla, in general, 
circumscissile at the apex, though the division sometimes 
takes place nearer to the centre. The fimbriated margin 
consists of branched threads formed of short, generally 
nearly square articulations. 
This species is as to its stroma, an Asteroma; but it 
contains distinct asci, which enclose eight very curious 
Sporidia, resembling in form the seeds of the Buck bean, 
being furnished with an appendage at the base, as in Spheria 
Thyrsus, Berk. In outward form it resembles somewhat 
Dothidea conspurcata, Berk.; but differs in the structure 
of the stroma, and if the minute elliptic bodies observed in 
that species be reproductive, most materially as to the spo- 
ridia, The stroma is so completely superficial, that there is 
no indication of the spots on the under surface of the leaves. 
Both in this and the last species, the fungus is accompanied 
by a species of Phyllocaris, which in Dothidea Zollingeri, 
sometimes overruns the spots. |
