•485] MELIOLA IN PORTO RICO — STEVENS 17 



surrounded by an areola of radiating mycelium, slightly rough, 140/* 

 in diam., spores 4-septate, 41 x 17/*, obtuse, slightly constricted. 

 On unknown dicotyledonous host, Aibonito, July 16, '15, 8470. 



11. Meliola perseae sp. nov. 



Colonies hypophyllous, irregular, black, 2-5 mm. in diam. My- 

 celium very crooked, branching irregularly, opposite, alternate or dicho- 

 tomous, very dark, 9/x thick. 



Capitate hyphopodia alternate or irregular, head cell oval to pyri- 

 form, cuneiform or angular. Mucronate hyphopodia alternate, variable. 

 Mycelial setae none. Perithecial setae none. 



Perithecium lOO-200/i, in diam., black, very rough with large 

 conical projections. Asci evanescent. Spores 4-septate, strongly con- 

 stricted, dark brown, ends rounded, 44 x 24/x. 

 On Persea gratissima Gaertn. Fig. 10. 



Las Marias, July 10, '15, 8212 (type). 



Characterized chiefly by absence of setae and its very irregular 

 mycelium; near to M. calva but differing from it in its rough peri- 

 thecium. 



12. Meliola lagunculariae Earle

 Aug. 11, '15, 9331. Joyuda, 331, '13, 363. 



The type was collected by Heller on the same host Jan. 1900, No. 

 4361a. Another collection was made by Heller at Catano, Jan. 7, '08, 

 No. 6417.

The hyphopodia in these specimens seem quite variable. In No. 

 7472, they are long, especially long in the stalk cell. The capitate 

 hyphopodia do not agree precisely with the figures of Gaillard. They 

 are more commonly obtuse or even truncated ; nor are they quite as long 

 as is called for in Gaillard 's description. Still, in view of the evident 

 variability of these structures in this species, it seems best to regard my 

 collections as M. longipoda.
