560 AUSTRALIAN FUNGI, 



contents, 24-31 x 3-3 h /x, average 28 x 3 /x; basidia very slender, 

 curved, 7-10 ^ long. 



Sandringham, Victoria; on stems of Lobelia gibbosa, LabilL; 

 Jan., 1903. 



It differs from SejUoria lobelice, Peck, in the absence of spots, 

 and the sporules there are 1 7-25 ^ long. Also from R. camimnuloi, 

 Fautr., in which the sporules are 40-60 x'2 fx. 



55. Septoria australle, n.sp. 



Spots on both surfaces, orbicular to irregular, at first ruddy- 

 brown and indefinite, then definite w^ith milk-white centre and 

 dark brown margin. Perithecia black, crowded, punctiform, 

 slightly erumpent, lenticular, membranaceous, with round papil- 

 late apical pore, 80-100 x 120-140 ^. Sporules hyaline, straight, 

 curved or flexuous, very slender, generally 3-septate, 30-45 x 0*75- 

 1 /i, average 35-40 /m in length. 



Kiewa Valley, Victoria; on Viola betonicifolia,Sin.; Xov., 1902 

 (Robinson). 



This is a very distinct species, and differs from the others 

 found on Viola as follows : — In S. violce, West., the perithecia are 

 epiphjdlous, and the spores are 20-30 x I fx. In S. violicola, Sacc, 

 the perithecia are also epiphyllous, and the spores are compara- 

 tively stout, being 24 x 7-8 /z. In S. hyalina, Ell. ct Ev., the w^hite 

 spots have a purple margin, and the non-septate spores are 20- 

 40 X 1 /x. 



56. Septoria confluens, n.sp. 



Spots greyish-white to grey, and occupying large portions of 

 leaf, or without distinct spots. Perithecia black, crowded, and 

 often confluent, globose to lenticular, dark brown by transmitted 

 light, membranaceous, fragile, with apical pore, 140-175 ^l. 

 Sporules hyaline, straight, sinuous or curved, 2-3 septate, generally 

 2-septate, not constricted at septa, rounded at both ends, or some- 

 what pointed at one or both ends, with granular contents, average 

 52-56 X 3J-4 ^,but may vary in length from 42 to 63 ix. 



Sandringham, Victoria; on fading and faded leaves of Mesem-
