The spore, even when coloured, may be without septa; then the 

 median septum is formed, next a second septum in one half, and 

 finally the third septum in the other half. 



It differs from the common H. sarmentorum, West., in the 

 sporules being longer and broader, and olivaceous in colour. It 

 was intermixed with Pestalozzia citrina, McAlp. 



45. Macrophoma brunnea, n.sp. 



Perithecia semi-gregarious, dark brown, covered by epidermis, 

 depressed globose, bright yellowish-green by transmitted light; 

 membranaceous, of parenchymatous texture; opening at surface 

 by pore, 200-230 ^. Sporules hyaline, elongated-ellipsoid to f usoid, 

 rounded at both ends, with coarsely granular contents, 21-24 x 

 5-7 /*; basidia hyaline, elongated, variable in length and breadth, 

 average 1 4 x 2-3 /^. 



Sandringham, VictoHa; on stems of Lobelia gibbosa, Labill.; 

 Dec, 1902, and Jan., 1903 (C. French, Jr.). 



It differs from J/", hueffelii (B. k C), Berl. k Vogl., found on 

 the living stems of Lobelia, in which the perithecia are globose 

 and at length free, and the oblong sporules 16-17 jx long. The 

 perithecia are brown in colour when closely inspected, and the 

 apical pore may enlarge considerably owing to the disruption of 

 the surrounding tissue. 



46. Massarinula phyllodiorum, n.sp. 



Spots on both surfaces, numerous, slightly raised, more or less 

 orbicular, often confluent, pallid or light brown, with distinct 

 darker margin. Perithecia few, black, at first immersed, then 

 erumpent, globose, subcarbonaceous, with apical pore, up to \ mm. 

 diam. Asci clavate to saccate, subsessile, 8-spored, 120-140 x 

 30-50 }x. Sporidia distichous or conglobate, colourless, lanceolate, 

 1 -septate and slightly constricted at septum, straight or slightl}^ 

 curved, 54-64 x 13-16 /iz. Paraphyses very copious, agglutinated, 

 apparently filiform, broken up into small segments.
