The spots produced on C. sylvestris are much smaller than 
on C. ramiflora, usually only 1-2 mm. in diameter. These on 
C. guianensis are intermediate in size. 
Cercospora thouiniae sp. nov. 
Spot indefinite diffuse, the diseased area showing above 
merely slightly discolored, below marked only by the ferru- 
ginous fungus. Conidiophores hypophyllous, abundant, long, 
lax, ferruginous smooth, crooked, slightly darker than the 
spores. Conidia, long, narrow, 58-72x5-7 », usually clavate, 
many-septate. 
On Thoutnia striata, Maricao, 751. 
Cercospora bernardiae sp. nov. 
Spots small, circular, 1-3 mm. in diameter. Yellow above, 
pale below, definite. Conidiophores epiphyllous in dense clust- 
ers, almost tubercular, short, about 35 » long, pale yellow. 
Conidia linear 51-68x7 p, obtuse, 3-many septate; very faintly 
straw tinted. 
On Bernardia bernardia, Guanica, 355a. 
The fungus is especially interesting since its general aspect 
is not that of a Cercospora and on account of its almost tuber- 
cular habit. 
Cercospora mikaniacola sp. 
Spot circular, small, 1-2 mm. in diameter, or by concentric 
enlargement, 5-10 mm. in diameter, sordid white in center, 
dark bordered, definite. Conidiophores hypophyllous, cespi- 
tose, fascicles of many conidiophores, or often solitary. Co-
