Alnus sp., Volcan de Agua, Dept. Sacatepequez, March 7, 1916, II, 
569- 
A heteroecious rust more common northward. It occurs also in 
Europe. Only uredinia have been seen among North American col- 
lections. It was also found by Kellerman at San Rafael, Feb. 3, 1907, 
on an undetermined Alnus. 
18. Cerotelium Fici (Cast.) Arth. (on Artocarpaceae). 
Ficus padifolia H. B. K., San Felipe, Dept. Retalhuleu, Jan. 13, 
1917, II, 707. 
Ficus sp., San Antonio Suchitepequez, Feb. 24, 1916, II, 527; 
Retalhuleu, Feb. 26, 1916, II, 536. 
The species was collected by Kellerman on F. aurea Nutt., at 
Gualan, Dept. Zacapa, Jan. i, 1906, II, 5456, and reported by Kern 
in Journ. Myc, /. c. 
A long-cycle rust, in America known only in the uredinial stage, 
although very abundant wherever Ficus grows. Some doubt still 
exists regarding the probable telial form of the American material, and 
there is a possibility that the generic assignment may not be right. 
Some mycologists prefer to list it as Uredo Fici Cast., or Physopella 
Fici Arth., or Kuehneola Fici Butl. 
19. Cronartium Quercus (Brond.) Schrot. (on Fagaceae). 
Quercus sp., San Rafael, Dept. Guatemala, Jan. 10, 1915, II, 56; 
Guatemala City, Feb. 14, 1917, II, 866. 
The species was collected by Kellerman on Q. tomentosa Willd., 
at Guatemala City, Feb. 2, 1905, II, 5304, and reported by Kern in 
Journ. Myc, /. c. Northward the species forms large aecial galls on 
the branches of pine, but they have not been seen in Guatemala.
