By D. McAlpine. 
( Communicated by J. H. Maiden.) 
(Plate xxxi. , figs. 1-5 of the upper division of the Plate.) 
Spot-like, sooty patches on leaf-stalks, stalklets, and upper and 
undersurface of leaflets, usually separate, occasionally run 
together. 
Mycelium chestnut-brown and hyphae thick-walled, septate, 
branched, 7 /x broad, with short, stout, ultimate branchlets. 
Appendages dark chestnut, thick-walled, rigid, erect, bluntly 
pointed and septate, the septa not always distinctly seen on 
account of the thickness of the walls. 
Perithecia black, globose, slightly warted, about 200 p in dia. 
Asci roughly fig-shaped, two-spored, transparent. 
Sporidia grub-like, usually 4-septate, constricted, chestnut-brown, 
37-45 x 14-17/x. 
On leaves of Dysoxylon rujum, Benth., from Richmond River, 
New South Wales (Maiden). 
The sporidia of this specimen are rather shorter and stouter 
than the normal, but otherwise the characters agree with those 
of the above species. 
This species is new for New South Wales.
