102 AUSTRALIAN FUNGI, 



38. Sph^rella antiiistiri^, n.sp. 



Peritliecia minute, black, punctiform, erumpent, gregarious,, 

 generally running lengthwise in lines, globose, membranaceous, 

 with apical pore, on both surfaces of withered portion of leaf 

 but mainly on upper, 100-120 fx diam. Asci oblong to oblong- 

 cylindrical, slightly swollen, then narrowing at base, sessile, with- 

 out paraphyses, 35-45 x 17-21 /n. Sporidia distichous or conglo- 

 bate, hyaline, elongate-elliptical, and tapering slightly towards 

 lower end, 1-septate, not constricted at septum, 14-15 x 4-4 J /a 

 (stained yellowish-green by Schulze's solution). 



Brighton (Sept., 1902), Leongatha, Vic. (Nov., 1902) ; on living 

 leaves of Anthistir^ia australis, K.Br. 



This species differs from S. (jraminicola, Fckl., in which the 

 asci are larger (75 x 12ju) and the sporidia are longer (15-20 x 

 3.J-4J /Li). Also from S. crus-gcdli, E. ik, K., in which the peritliecia 

 are differentl}^ arranged; the asci are considerably longer and the 

 sporidia, although about the same size, are constricted at the 

 septum. 



39. Sph.erella cassyth.e, n.sp. 



Peritliecia minute, punctiform, scattered, black, dark olivaceous 

 by transmitted light, erumpent, membranaceous, depressed-globose, 

 70-90 fj. diam. Asci clavate to elongate-clavate, often tapering 

 into a more or less slender stalk, 8-spored, 32-37 x 9-12 fj.. Sporidia 

 biseriate, hyaline, cylindrical, slightly tapering towards one end, 

 1-septate, not constricted at septum, guttulate, 9 x 3 /x. 



On filiform stems and branches of Cassytha glahella^ R.Br. 



This fungus causes blackening and shrivelling of the parts 

 attacked, and is comparatively rare. 



40. Urocystis colchici (Schlecht.), Rabenh. 



Near Melbourne, Vic; on living leaves of Wurmhea dioica^ 

 F.v.M.; Sept., 1902. 



The plant was in flower when the fungus was obtained and it 

 affected the lower leaves badly, while the upper leaves only 

 showed indications of it.
