conidiophores, hyaline, l-septate, fusoid, acute at each end, 
13-20x214-3 p. 
On Phyllachora peribebuyensis Speg. on Miconia sp., Mar- 
icao, 3610. 
While this fungus bears some resemblance to C. macro- 
sportum Speg., it differs essentially from it in several char- 
acters, particularly in the shape of the spores. 
Diplosporium Bon. 
Diplosporium album Bon var, fungicolum. 
On Parodiella cayapomae, Garman. 
On Cayaponia, Utuado, 4360. | 
Blastotrichum Corda 
Blastotrichum micomae sp. nov. 
Mycelium hyaline, forming white spots on under sides of 
leaves. Spot circular, indefinite, 2-5 mm. in diameter, pale to 
yellow above. Aerial mycelium abundant, creeping and 
branching profusely and irregularly, 3-5 » thick. Erect my- 
celium mainly branching dichotomously, sometimes geniculate. 
Conidia 0-3-septate, falcate, acute, 17-30x3-5 », Associated 
with and probably belonging to Borinquenia, on Micomia laewi- 
gata, Maricao, 4822, Utuado, 6871, 6862, Aguas Buenas 302. 
Separated from previously described species by its parasitic 
habit and its association with Borinquenia. (This is essentially 
a Fusarium without the sporodochium, i.e., having the conidio- 
phores of the Moniliaceae. ) 
Monogrammia gen. nov. 
Conidia on short, branched, hyaline conidiophores, one- 
celled, hyaline, with six lobes all in one plane. 
Monogrammia miconiae. sp. nov. Fig. 9. 
Mycelium hyaline, hypophyllous, in small, 1-5 mm., circular 
spots. Conidiophores short, usually simple; conidia adhering 
in clusters, hyaline, continuous, six-lobed, shaped like a mono- 
gram of the letters H. and I; attached to the conidiophores by
