Buffalo Mountains, Vic. (Walter); on living leaves of Driniys 

 uromatica, F.v.M. 



The diseased portion of the leaf is a light grey on the upper 

 surface and a pale fawn on the under, so that it is distinctly 

 marked off from the ordinary green portion. The conidia are 

 guttulate in the early stages, and there is a tendency to segrega- 

 tion of the protoplasm as if there was spurious septation. On 

 treatment with Schulze's solution they are stained yellowish and 

 sometimes a deep brown, with marked separation of the proto- 

 plasmic contents. 



This species differs from G. magnolice, Passer., in which the 

 conidia are from 8-12 /x long; also from G. haynaldianiLin, Sacc. 

 & Roum., in which they are 12-15 /^ long. 



I have named this species after Mr. C. Walter, of Melbourne, 

 who found it, and who has contributed a number of other species 

 to the fungus-flora of Australia in the course of his extensive 

 •botanical collecting trips. 



31. Helminthosporium gramineum, Rabh. 

 Killara, Yic; on leaves and leaf-sheaths of Barley; Sept., 1902. 



This fungus has only hitherto been observed in Germany and 

 Sweden. It attacks the lower leaves, causing them to wither and 

 become yellow, although it does not seem to produce great injury 

 otherwise. It does not attack cereals other than Barley. 



32. Hendersonia grandispora, n.sp. 



Perithecia densely gregarious, immersed, black, dark brown by 

 transmitted light, globose, membranaceous, 120-140 /x diam., 

 forming black expanded indeterminate patches, more particularly 

 on upper surface of leaves. Sporules numerous, smoky-browDj 

 cylindrical, rounded at both ends, straight but generally slightly 

 curved, 3-5-septate, not constricted at septum, with finely granu- 

 lar contents, 50-60 x 5-6 /x.

 sp.; Sept., 1899.
