Gloeosporium ochraceum 



Causing large arid spots of irregular shape, especially upon 

 the ends of the leaves, alutaceous, with a dark brown border : 

 acervuli amphigenous, raising the epidermis in dark pustules be- 

 coming erumpent : conidia ochraceous in the mass, ovate, some-

 partment of Agriculture, January, 1900, F. W. P. 



It will be observed that while the general appearance produced 

 by the presence of Gloeosporium ochraceum on Cinnamomum aro- 

 maticum is very similar to that of Gloeosporium cassiae on Cinna- 

 momum cassia, they differ widely in microscopic details. 



Gloeosporium oleae 



Spots white, arid, with an inconspicuous brown border, large, 

 sometimes occupying about one-fifth of the leafs surface : acervuli 

 epiphyllous, numerous, long, covered by the epidermis, erumpent, 

 dark, almost black : conidia oblong or ovate-oblong, sometimes 

 slightly inequilateral, often bi-guttulate, 9-15 X4-5 fi.

Colletotrichum setosum 



Spots large, irregular, arid, yellowish-white, with purple bor- 

 der : acervuli amphigenous, not erumpent, numerous, minute, 25—
