UREDINALES OF GUATEMALA 
Uredinia hypophyllous, scattered, round, 0.3-0.5 mm. across, 
early naked, pulverulent, chestnut-brown, ruptured epidermis con- 
spicuous; urediniospores globoid to obovoid, 19-26 by 24-30 /z; wall 
chestnut-brown, 1.5-2.5 thick, moderately and finely echinulate, 
the pores 2, near the hilum, or rarely 3, all near the hilum or one of 
the three near the apex. 
Telia chiefly hypophyllous, scattered, small, round, 0.5-0.8 mm. 
across, early naked, pulverulent, blackish-brown, ruptured epidermis 
inconspicuous; teliospores oblong or ellipsoid, 24-29 by 40-45 /jl, 
rounded or obtuse above, rounded below, scarcely constricted at 
septum; wall chestnut-brown, 3-4 /jl thick, lighter colored and thicker 
at apex, 5-9 fjL, equally thickened over pore of lower cell, closely and 
prominently verrucose; pedicel colorless, once to twice length of spore, 
sometimes attached obliquely. 
The type of the species is a collection by Kellerman 608/, made 
Feb. 6, 1907, on Volcan Acatenango, 6000 feet alt.. Dept. Sacatepe- 
quez, on Eupatorium phoenicolepis guatemalensis Robins., the host 
being determined by J. M. Greenman, and the name of the fungus 
attached by Dr. F. D. Kern.

Uredinia hypophyllous, scattered, or somewhat gregarious, round, 
small, 0.1-0.3 mm. across, early naked, pulverulent, cinnamon-brown, 
ruptured epidermis barely noticeable; urediniospores globoid or obo- 
void, 23-29 by 26-32 />(; wall dark cinnamon-brown, thin, 1-1.5 ^u, 
closely and finely echinulate, the pores 2, sometimes 3, approximately 
equatorial. 
Telia amphigenous, scattered, 0.5-1 mm. across, early naked, 
somewhat pulverulent, blackish-brown, ruptured epidermis barely 
noticeable; teliospores broadly ellipsoid, 30-35 by 38-45 ^x, rounded 
at both ends, slightly constricted at septum; wall chestnut-brown, 
rather thick, 2.5-4 slightly thicker above by a lighter umbo, 5-6 /z; 
pedicel colorless, persistent, the wall thickened often nearly obliterat- 
ing the lumen, the surface granulose at base, twice to thrice length of 
spore, 6-7 IX in diameter. 
This species difl^ers conspicuously from P. inanipes Diet. & Holw., 
with which it has been confused, by having urediniospores of the usual 
globoid or obovoid form, while in P. inanipes they are strongly flat- 
tened above and below, forming an oblate spheroid, and also by the
