Mycologia 



mm. in diameter, early naked, pulvinate, golden-brown, becom- 

 ing cinereous by germination, ruptured epidermis inconspicuous ; 

 teliospores oblong-obovoid, 13-16 by 30-40 /x, rounded above, 

 somewhat narrowed below, slightly constricted at septum ; wall 

 pale golden-brown, sometimes lighter below, 1-1.5 /x thick, slightly 

 or not thickened at apex; pedicel colorless, once to twice length

A short-cycle rust, probably without pycnia, for which the 

 type selected was collected by Professor Holway in Guatemala, 

 on Buettneria lateralis Presl, at Escuintla, Feb. 17, 1916, 501. 



60. Puccinia Violae (Schum.) DC. (on Violaceae) 

 Viola nannei Polak, Volcan de Irazu, Cartago, Dec. 23, 191 5, II, 



III, 289; El Alto near Cartago, Jan. 16, 1916, II, III, 433. 

 A widespread, long-cycle species, with aecia, much more abun- 

 dant in temperate regions. 



61. Puccinia Fuchsiae Syd. & Holw. (on Onagraceae) 

 Lopezia hirsuta Jacq., Volcan de Irazu, Cartago, Dec. 23, 191 5, 

 282 ; Tres Rios near San Jose, Jan. 17, 1916, 438. 

 A short-cycle rust found on the same host in Guatemala and

62. Puccinia fumosa Holw. (on Polemoniaceae) 

 Loeselia sp., San Jose, Dec. 26, 191 5, II, iii, without number. 



A long-cycle rust with all spore forms, known from Mexico 

 and Guatemala. 



63. Puccinia Hydrocotyles (Link) Cooke (on Ammiaceae) 



Hydrocotyle umbeilata L., San Jose, Dec. 15, 1915, H> 2 59- 



The species was also collected on H. mexicana Cham. & Schl., at 

 San Jose, by A. Tonduz, August, 1908, showing uredinia. 



It is a long-cycle rust whose initial stage is yet unknown, 

 unless the form described by Spegazzini as Aecidiolum Hydro- 

 cotyles may belong here. It is common in the warmer parts of 

 America, and less common in other parts of the world.
