OTHER PORTO RICAN FUNGI. 



Besides my own collection, discussed in the preceding paper 

 by Professor Earle, only two collections of fungi Have been re- 

 ported from the island. The first was made by Carl Schwan- 

 ecke, who resided from 1 847-1 850 at Humacao on the east coast. 

 His fungi were determined by Klotzsch, who enumerated them 

 in Linnaea, 25: 364-366. 1852. 



The second and larger collection was made by P. Sintensis, 

 who spent the years 1 884-1 887 making collections in all parts 

 of the island. The fungi were determined by J. Bresadola, 

 P. Hennings, and P. Magnus. They are listed in Engler Bot. 

 Jahrb. 17: 489-501. 1893. 



The new species in these two collections are here printed 

 in boldface type. The original arrangement of species is fol- 

 lowed in both cases.
