525] MELIOLA IN PORTO RICO — STEVENS 57

Manati, Nov. 5, '13, 4285. 

 On Myrcia deflexa (Poir) P. 



El Alto de la Bandera, July 14, '15, 8268, 8268, 8672. 



This collection is heavily overgrown by parasites and the determina- 

 tion is therefore not fully reliable. The typical setae were not seen but 

 the character of the mycelium and capitate hyphopodia were those 

 of M. helleri.

In many cases the colonies, particularly epiphyllous colonies, lack 

 the usual velvety appearance, have few setae, a loose mycelium instead 

 of the dense mycelium, and lack the numerous hairs that characterize the 

 large black hypophyllous blotches. The forking of the setae seems to be 

 the exception rather than the rule.
