Ad folia viva Randiae aculeatae L. in insula St. Jan Indiae 
occidentalis. (Leg. F. Boergesen). 
Our diagnose of this fungus is originally founded upon specimina 
collected by C. Raunkiær and contains only microscopical characters, 
as the macroscopical appearance of the fungus was found to be 
nearly congruent with that of the type-species (efr. the description: 
Hedw. 1897 pag. 371). The material collected by Børgesen, 
however, also macroscopically differs from Rehm's description, and 
our examination of the original specimen of Phyllachora Randiae 
Rehm") states this difference to be very conspicuous. 
After this we have preferred to extend our original diagnose, 
as more as a conidial stage of the fungus in the meantime has 
been found by us.
