100 AUSTRALIAN FUNGI, 



It differs from //. eucalypti, Cooke k Hark., in which the peri- 

 thecia are collected in orbicular spots, and the 3-septate sporules 

 are only 20 ^ long, 



.')3. Phoma romule.e, n.sp. 



Perithecia minute, black, punctiform, gregarious, erumpent, 

 globose, dark brown by transmitted light, membranaceous, firm, 

 of parenchymatous texture, with distinct mouth, 100-112 /x 

 diam. Sporules hyaline, minute, ellipsoid, i\ x 2-3 /x. 



Armadale, Yic: on leaves of Bomuha hnlhocodiiim, Sebast.; 

 Aug., 1902. 



It differs from P. iridic, Cooke, in the perithecia being erum- 

 pent, and the sporules much shorter. 



This fungus seemed to kill the plant, since the leaves were 

 quite withered except for a small green portion sometimes towards 

 the base, and the plants badly affected had generally lost their 

 hold of the soil. This introduced plant is widely spread around 

 Melbourne, but so far only occasional diseased plants have been 



met with. 



34. Phoma vittadinle, n.sp. 



Perithecia minute, black, punctiform, erumpent, slightly 

 gregarious, globose, membranaceous, tough, with apical pore, 

 100-130 |x diam. Spores hyaline, elliptical to oval, minute, 1- 

 guttulate, stained yellowish-green by Schulze's solution, 4-4J ^ 

 long; basidia slender, hyaline, about same length as spore. 



Malvern, near Melbourne, Vic; on dead or dying branches of 

 Vittadinia australis, Rich.; Sept., 1902. 



It differs from P. herharnm, West., in the smaller and shorter 

 spores, and in being only 1-guttulate. 



35. Septoria bet^j West. 

 Port Fairy, Vic; on leaves of Beta vulgaris, L.; Aug., 1900. 



36. Septoria perforans, n.sp.
