high when fully mature, chestnut-brown becoming yellowish and 



pulverulent by germination; teliospores 2-celled, ellipsoid, 16-21 by 



37-48 fx, somewhat narrowed above and below, slightly constricted 



at the septum, wall pale cinnamon-brown, uniformly thin, 1-2 /*, the 



pores 2 in each cell, near the septum; pedicel cylindrical, uniform,

 arbutifolia and Amelanchier sp. 



"O. Pycnia chiefly epiphyllous and fructicolous, gregarious, 

 rather crowded in small groups 0.5-1 mm across, on discolored 

 spots 2-7 mm. across, noticeable, honey-yellow becoming brownish, 

 globoid, rather large, 144-170 /t in diameter by 112-150 /x high; osti- 

 olar filaments 60-75 /a long. 



"I. Aecia hypophyllous, caulicolous, and fructicolous, occasion- 

 ally solitary, usually gregarious, sometimes few together but more 

 often aggregate in large groups, borne in gall-like, frustum-shaped 

 protuberances (1-2 mm. high) of a reddish-brown color and more 

 or less consolidated at the bases in the groups, at first cylindrical, 

 2-2.5 mm. high by 0.2-0.4 mm. in diameter; peridium soon becoming 

 finely fimbriate to base, partially dropping away, and narrow hygro- 

 scopic, becoming curved or even coiled when wet, 12-18 a thick by 

 J 50-300 fx long, or more, in the sides of the peridium, much shorter 

 toward the apex, the outer wall rather thin, 2-3 jx, smooth, the inner 

 wall, 4-6 fx thick, rather coarsely verrucose, the side walls verrucose 

 on inner half with roundish or somewhat irregular papillae, more 

 thickly crowded toward the inner side, the outer half of the side walls 

 smooth; aeciospores globose, small, 18-22 jx in diameter; wall light 

 cinnamon-brown, 1.5-2.5 [x thick, rather finely verrucose, the pores 

 6-8 scattered." North American Flora, v. 7, p. 202 (1912).
