the prominent subcuticular pycnia, and the long and numerous aecia, 

 but especially on account of the very odd spores, which are exceedingly 

 large, with coarsely marked thick walls, much thickened above. The 

 characters of the pycnia and aecia are so unlike those of autoecious 

 species on Malpighiaceae that it is assumed to be heteroecious. The 

 fact that the pycnia are subcuticular indicates that it does not belong 

 to the Uromyces-Puccinia group but to some genus of the Raveneliatae 

 or Uropyxidatae. Both host and fungus of a specimen in the New 

 York Botanical Garden, collected at Rancho Guerro, Jalisco, Mexico, 

 June 15, 1892, by M. E. Jones, said to be on an Ericaceous host, agree 

 perfectly with this Guatemalan specimen. Because of the long, bladdery 

 peridia there is a resemblance to Peridermium, and the Mexican speci- 

 men has been so labeled, but there can now be no doubt that it belongs 

 here. 



12. Balansia trinitensis Cook & Massee 



On Panicum sp. indet. 



Sierra del Mico, between Los Amates and Izabal, alt. 360 m. (1200 

 ft.), Depart. Izabal, Gautemala, C. A. February 23, 1907. 



W. A. Kellerman, No. 6079. 



This fungus was found in a single locality, a moist mountain ra- 

 vine, infesting a dense clump of the large grass which for the most 

 part had succumbed to the parasite. The material was submitted to 

 Professor Atkinson for identification. This species was first detected in 

 Trinidad, the host being Panicum palmi folium. 



13. Coleosporium plumierae Patouillard 



On Plumiera rubra L. 



El Palmar, alt. 615 m. (2050 ft.), Depart. Quezaltenango, Guate- 

 mala, Central America. February 11, 1906. 



W. A. Kellerman, No. 5460. 



The material was placed in the hands of Frank D. Kern for identi- 

 fication; he reports as follows: This is the first time this species has 

 been collected on the continent, the other collections coming from the 

 West India Islands. The host has been identified by John Donnell Smith. 



14. Puccinia conoclinii Seymour 



On Eupatorium rafaelense Coulter. 



Volcano Cerro Quemado, alt. 2700 m. (9000 ft.), Departmento 

 Quezaltenango, Guatemala, C. A. February 8, 1906. 



W. A. Kellerman, No. 5449. 



The host was determined by J. M. Greenman; the Rust was identi- 

 fied by Frank D. Kern. The Rust has been collected in the United States 

 on Eupatorium (Conoclinium) coelestinum and Eupatorium incarnatum, 

 extending from Illinois to Louisiana ; in Guatemala it was obtained on 

 Eupatorium pycnocephalum and on the host named above.
