The first number on the announced scientific program was a 

 paper by Dr. J. K. Small on "Exploration of Cape Sable, Flor- 

 ida." The speaker gave a brief description of the locality ex- 

 plored and exhibited a large number of photographs of the vege- 

 tation of this region. 



The second paper was presented by Dr. E. W. Olive on " Porto 

 Rican Rusts." The speaker's abstract follows: 



"Professor Arthur's recent list of the 'Uredinales of Porto 

 Rico' (Mycologia, 7: 168, 227, 315; 8: 16) based largely on the 

 collections of F. L. Stevens in 1912-14, and again during the 

 summer of 1915, enumerates a total of 135 from the Island, of 

 which Dr. Stevens collected 122. During a recent collection 

 trip to Porto Rico, lasting from Feb. 23 to April 26, 1916, Pro- 

 fessor Whetzel of Cornell and Dr. Oliv^e of the Brooklyn Botanic 

 Garden collected again the majority of the forms found by 

 Stevens, together with a number of species new to Arthur's list 

 as well as some new to science. Among the latter certain Endo- 

 phyllum-like rusts, six or perhaps seven in number, are of special 

 interest. Besides an abundance of dried specimens, considerable 

 fixed material, particularly representatives of the short-cycled 

 rusts, was brought back for microscopic study. 



" Attention was called in particular to the relative abundance of 

 the uredo forms; to the strictly localized distribution of certain 

 rusts; to the apparent absence of serious rust epidemics; and to 

 the comparative scarcity of rust fungi in the primeval forests of 

 Porto Rico." 



Dr. W. A. Murrill followed with a paper on "A New Poisonous 

 Mushroom." This new species of Panaeolus is described in the 

 May number of Mycologia. The speaker exhibited dried speci- 

 mens of this fungus and of related forms and water color illustra- 

 tions of fresh specimens of the poisonous species. 



Adjournment followed.
