Ou Spondias mombin L. 



Maricao, April 3, '13, 749. 



Perithecium and appendages quite similar to those of M. tortuosa 

 but distinct from that species in mycelial characters. 



The colonies are usually densely overgrown with parasites which 

 make the characters difficult to determine. The absence of mycelial 

 setae, the presence of the long perithecial setae, the characteristic radia- 

 tion of mycelium from the base of the perithecium, and the character- 

 istically angular capitate hyphopodia are each distinctive.

On Piper medium, Jacq. 



Vega Baja, July 2, '15, 7752. A specimen determined by Earle is 

 also in the Bronx collection. 

 On Piper peltatum L. 



Heller, No. 6388, Dec. 25, 1902, Ponce. The type was on leaves of 

 Piper from Brazil. It has also been reported upon Dickensonia. 



This form agrees with the descriptions except that the spores are a 

 little too small, 37/a, while the description calls for 49-54/x. It is almost 

 always present where the host is found, often covering the leaves with 

 its black coating. 



27. Meliola chamaecristicola sp. nov. 



Colonies epiphyllous, circular, 1-2 mm. in diam. Mycelium black, 

 forming a rather close network, 7jx in diameter. 



Capitate hyphopodia small, alternate, not crowded, 1 per cell, cells 

 about 14 to llfji long, head cell ovoid, 14 x 10/a, the basal cell 3/* long. 

 Mucronate hyphopodia alternate or opposite, bottle-shaped, 14-16 x 6fJL. 

 Mycelial setae none. Perithecial setae few, straight or slightly curved, 

 80 X 4/A. Tip obtuse, dark throughout.
