700 NEW SOUTH WALES FUNGI 



lets, 5^-7i/x broad. Perithecia membranaceous, generally orbicular, 

 sometimes elongated-oval (260x140 jj.), flattened, composed of 

 radiating transversely divided filaments, with adherent fibrils, 

 brown, vai'iable in size, 56-188 /x in diameter. Jsci ovate, 8- 

 spored, 56-84 x 41-52 fx. Sporidia dark brown, elliptic, uniseptate, 

 slightly con.stricted, 33-37 x 17-19 /x. 



On leaves of Geitonoplesium cymosum, Cunn. July. Murwill- 

 umbah, N.S.W. (Baker, 5). 



The sporidia are at first colourless, then olive-green, and finally 

 of a very dark brown colour. When the asci are treated with 

 potassium-iodide iodine the sporidia, as well as the contents of 

 the inner wall, are a beautiful chestnut-brown, and outside of 

 that a pale green colour.

Epiphyllous. Minute, black, superficial, scattered, velvety 

 spots. Hyphce next to matrix, creeping, colourless, septate, 

 branched, forming a gelatinous network attaching the fungus to

 the bi'own filaments, 2-4 ^i bi'oad. Brown hypha; thick-walled, 

 and sometimes rough, septate, much branched, branches often 

 opposite, 7| /i broad, ultimate branchlets numerous, short, stout, 

 1-2 septate. Appendages simple, dark chestnut, thick-walled, 

 rigid, erect, septate, rounded at apex or usually variously toothed, 

 up to 11 /x broad. Perithecia dark brown, globose, depressed, 

 irregular at margin with a few adherent fibrils, 70-84 /x diameter.

In Meliola bidentata, Cke., the appendages are bidentate at the 



tips, but here thej^ are moi'e numerous and usually forming a 



whorl. As this is a very characteristic feature, it is embodied in 



the specific name.
