la Bandera, 8273, 7559, Coamo 605. On Inga vera Maricao, 
762. It differs decidedly from Zukalia fusispora Pat. as de- 
scribed on Inga. 
It is often overgrown by a fungus which has a fine white 
mycelium which weaves into a close mat forming white spots 
from a few millimeters to a centimeter or more in diameter. 
Perisporium bromeliue sp. nov. 
Spots hypophyllous, smoky, 1-2 cm. in diameter. Myceitum 
superficial, abundant, brown-black, septate, sparsely branched, 
Perithecia irregular, globose, 110-120 », no ostiole. Asci ovate 
fasciculate from base of perithecium, numerous, 50-58x20 p, 4- 
spored, no paraphyses. 
Spores fusiform, straw-colored, irregularly 0, 1, 2 or 3-sep- 
tate, 30x8-10 uw, not constricted at the septa.

This is very common on the host in all parts of the island. 
The smoky blotches are so usual as to seem to belong to the 
plant. The perithecia are almost exclusively found in the fur- 
rows or grooves between the heavy veins. 
This fungus in its perithecium clearly shows its relationship 
to the Perisporiales, but within that order its position is much 
less certain. The spores vary much in septation, being from 1 
to 4-celled in spores which are fully mature. In the Phaeos- 
porae there is a general resemblance to Cephalotheca but the 
ascus structure is not that characteristic of that genus. In the 
Phaeophragmiae where the fungus evidently belongs, it differs 
distinctly from Meliola in many respects, especially in character 
of mycelium and spores: From Schenckiella in spore charac- 
ters: from Perisporina in mycelial and spore characters. Its 
agreement seems to be most close with Perisporium from the 
description of which it differs in its 4-spored ascus. Notwith- 
standing this difference, however, it seems best to place the 
species in Perisporium.
