126 AUSTRALIAN FUNGI, 



towards the base of the stem and not freely exposed to the light. 

 Phoma labiatariwi, Cooke, occurs on dead stems. 



78. Septoria hypochceridis (Allesch.), McAlp. 



Syn. Rhahdospora hypochmridis, Allescher (Hedw., xxxv., 163, 

 1897). 



Spots on both surfaces of leaf, dirty grey to brownish, somewhat 

 round, with purplish margin, usuall}^ about 5 mm. diam. Peri- 

 thecia very minute, black, scattered or gregarious, erumpent, 

 olivaceous by transmitted light, depressed -globose to lenticular, 

 membranaceous, of parenchymatous texture, with apical pore, 

 70-1 00 /i diam. Sporules hyaline, filiform, very slender, straight, 

 curved or slightly flexuous, guttulate, 22-32/x long. 



Armadale, near Melbourne, Vic; on Hypochceris radicata, L.; 

 October, 1903. 



This species was associated with Puccinia hypochoeridis, Oud., 

 which occurred on the same spots. It differs from S. mougeoti, 

 Sacc. k, Roum., occurring on Hieracium, in the nature of the 

 spots, and in the shorter spores. 



It was first determined on the dead stems of this cosmopolitan 

 plant in German}^, and assigned to the genus Rliahdosj^ora by 

 Allescher, but since it occurs on the leaves as well and forms 

 spots, it is a true Septoria. 



79. Sph^rella rubicola, n.sp. 



Perithecia on silvery-grey patches, minute, black, depressed- 

 globose, scarcely erumpent, scattered, dark browm by transmitted 

 light, membranaceous, with relatively large, round, papillate 

 mouth, 140-190/Lt diam. Asci obclavate, shortly stalked, rounded 

 at apex, without paraphyses, 8-spored, 63-70 x 18-21/x. Sporidia 

 generally biseriate, cjlindric-oblong, hyaline, with finely granular 

 contents, 1 -septate, not constricted at septum, rounded at both 

 ends, gradually tapering towards lower end, two cells about 

 equal in length, upper cell broader, 21 x 7/x. 



Arthur's Creek, Vic; on still green and brown branches of 

 Mubus parvifolius, L.; August, 1902.
