shaped crown, closely and finely reticulate, appearing verrucose under the lower powers

Telospora bauhiniicola Arth. Résult. Sci. Congr. Bot. Vienne 346. 1906. 
O. Pycnia epiphyllous, few, gregarious in small groups, usually opposite the telia, puncti- 
form, browtiish, depressed-globoid, 60-130 , in diameter, 30-65 » high; ostiolar filaments com- 
pact, short. 
IIL. Telia at first hypophyllous, becoming also somewhat epiphyllous, numerous, scat- 
tered or in small groups, roundish, small, 0.2-1 mm. across, early naked, pulverulent, chocolate- 
brown, surrounding epidermis inconspicuous; teliospores globoid or broadly ellipsoid, 14-21 
by 18-26,, rounded at both ends; wall cinnamon- or chestnut-brown, thick, 3-4 y, thicker 
at apex, 4-7 », with a broad lighter-colored umbo, finely reticulate; pedicel pale or colorless, 
often roughened below, rather fragile, but often two or three times as long as the spore.

4, Teleutospora abbreviata (Arth.) Arthur & Bisby. 
Uromyces abbreviatus Arth. Bull. Torrey Club 42: 587. 1915. 
O. Pycnia hypophyllous, scattered among the telia, inconspicuous, deep-seated, dark 
honey-yellow, globose or flattened-globose, 115-2004 in diameter, 95-1404 high; ostiolar 
filaments dense, often falling away, up to 60 uw in length. 
Ill. Telia hypophyllous, rarely also epiphyllous, scattered over large areas, often densely 
clustered, roundish, 0.2-0.7 mm. across, early naked, pulverulent, chocolate-brown, surrounding 
epidermis at first evident, later often hidden by the loose spores; teliospores ellipsoid or 
irregularly obovoid, 21-26 by 27-40 » (sometimes variable in size, and larger), rounded above, 
rounded or narrowed below; wall chestnut-brown, 2-3 4 thick, 3-5 thick at apex, with 
a slight umbo over the pore, smooth; pedicel colorless, delicate, fugacious, half as long as 
spore or less. 
This species is correlated with Pucciniola Psoraleae (Peck) Arth., the telia being mor- 
phologically indistinguishable from those of that species. The two forms when more fully 
studied might possibly be united under one name.

Uromyces Tranaschelii Sydow; Tranz. Ann. Myc. 8: 20. 1910. 
O. Pycnia hypophyllous, scattered among the telia, or in groups, noticeable, dark-yellow, 
globoid or flask-shaped, 100-145 » broad by 75-130 « high; ostiolar filaments dense, agglutinate 
into a truncate column, 50-80 » in height, 50-70 w in diameter at the ostiole.
