Capitate hyphopodia alternate, distant, usually about 120/x apart, 

 cylindrical, 20 x 17/x, often irregular or curved, the basal cell S-S/a 

 long, Mucronate hyphopodia opposite, bottle-shaped, about 24/* long. 

 Perithecial setae none. Mycelial setae very few, scattered, straight or 

 slightly curved, 1000,tt long, dark throughout. Tip obtuse to acute. 



Perithecia 150 to IGOju,, smooth, subtended when young by an areola

Guayanilla, July 14, '15, 3541 (type). 



This is closely related to M. amphitriclia, M. amhigua and M. coral- 

 Una, differing from the last two in spore size ; differing from the first, 

 in abundance, length and color of setae, and in character of capitate 

 hyphopodia and mycelium.

Maricao, July, 19, '15, 8818. 



These specimens conform perfectly with type material kindly sup- 

 plied by Dr. Spegazzini. 



The most distinctive characters are the regularly shaped, capitate 

 hyphopodia and the black, truncate setae. 



71a. Meliola tabernaemontanae. var. porsteroniae var. nov. 



The specimens on Forsteronia agree with the type quite closely, 

 but present constant differences in the setae and capitate hyphopodia 

 as follows : The setae are long, about 700/t, and taper to an acute apex. 

 The capitate hyphopodia are larger and more angular than in the type.
