374 AUSTRALIAN FUNGI, 



Ardmona, Vic. (Robinson, 284); very common, on both surfaces 

 of the leaf-blades but mostly on outer or lower, and sheaths of 

 Danthonia penicillata, F.v.M., Sept. 1899, and May, 1902. 



This is a true and destructive parasite, causing the leaves to 

 become dried up and brittle. The black elongated pustules 

 arranged in lines give the appearance of 'black rust' and the 

 aeneral resemblance to a rust is heightened by the occurrence of 

 ruddy spots, which is characteristic at the commencement of the 

 development of perithecia. While Z>. penicillata was severely 

 attacked, other species adjacent were quite free. 



2. Camarosporium dolichi, n.sp. 



Perithecia gregarious, erumpent, black, dark golden-brown b}'- 

 transmitted light, globose, membranaceous, with rotund papillate 

 mouth. Sporules olivaceous, oblong, 4-septate, muriform, with 

 median septum very distinct; 16 x 9 /x. 



Armadale, near Melbourne, Vic; on leaflets of Dolichos lablab, 

 L.; July, 1901. 



3. Camarosporium nigricans, n.sp. 



Perithecia very minute, globose, black and golden-brown by 

 transmitted light, numerous, membranaceous, seated superficially 

 on mycelial threads, no apical pore observed, 50-57 /x diam. 

 Sporules olivaceous to golden-brown, elliptical, generally 3-septate 

 and constricted at septa, with occasionally 1-2 longitudinal septa, 

 13-15 X 61 /x. 



Croydon, Vic; on apple twigs; June, 1902. 



It differs from C. mali, Ell. &, Ev., in the much smaller 

 perithecia, and in the sporules not being 5-8 septate; the specific 

 name is indicative of the blackening of the twigs by the fungus. 



4. Capnodium (?) CASUARiN^, n.sp. 



Forming black, soot-like incrustations all over branches and 

 branchlets, not readily separating. Hyphse creeping, septate, 

 branching, fuliginous, firm, thick-walled. Cerato-pycnidia yellow- 

 ish-green to dirty green, very elongated, irregularly shaped.
