Pcrithecia sunk in tlie matrix, with ostiola erumpcnt, ellipsoid 

 or globoid, 150-200/* in diam. and nearly 125 ;u, in height; peri- 

 thecial wall black, psendo-parenchymatous ; ostiola 45-50 ju, long, 

 about 40 /x across; asci clavate-cyHndric, thick-walled above, 

 60-70 X 13-18 ;tt, paraphysate, octosporous ; paraphyses filiform, 

 abundant, forming thick periphysatic tissue; ascospores sub- 

 biseriate, fusoid or ellipsoid, obtuse, minutely granulate, 1&-22

Mostly appears in presence of Macrophoma minuta Berl. the 

 pycnidia of which are surrounded by blackened hyphae commonly 

 known as subiculum. which occur simultaneously with the forma- 

 tion of perithecia of the present species. Symptoms of the two 

 are identical, shown by minute, gregarious, elevated spots covering 

 certain areas of the twigs. As to the evidence of genetic relation- 

 ship between the two. since no ascogenous form of the former 

 species has been reported, the new name is given as above.
