11. PHRAGMOPYXIS Dietel, in E. & P. Nat. Pfl. 1’**: 70. 1897. 
Cycle of development includes pycnia, aecia, uredinia and telia; autoecious. Pycnia 
subcuticular, other sori subepidermal. 
Pycnia conoidal, with ostiolar filaments. 
Aecia erumpent, definite, encircled by paraphyses. Aeciospores catenulate; wall color- 
less, closely verrucose. 
Uredinia erumpent, definite, encircled by paraphyses. Urediniospores borne singly on 
pedicels; wall pale, verrucose, pores indistinct, scattered. 
Telia erumpent, indefinite, encircled by paraphyses. ‘feliospores free, three-celled by 
transverse septa, verrucose; wall laminate, inner layer firm, colored, outer layer gelatinous, 
translucent, overlaid by cuticle; more than one pore in each cell and lateral.

O. Pyenia epiphyllous, sparingly produced, in groups with aecia, brownish-yellow, 
punctiform, inconspicuous, subcuticular, conical, small, 60-80 # broad, half as high ; ostiolar 
filaments 20-24 uv long. 
I. Aecia amphigenous, more largely hypophyllous, small, crowded in small circular 
groups, ruptured epidermis noticeable, pale-yellow; paraphyses peripheral, few, small, 
linear, 5—7 by 24-29 #, straight or variously bent and incurved, wall usually thick, some- 
times nearly obliterating the lumen, smooth, colorless; aeciospores globoid or ellipsoid, 
13-17 by 15-192; wall colorless, thin, 1», finely and closely verrucose. 
II. Uredinia caulicolous, oblong or elongate, small, bullate, soon naked, pulverulent, 
pale brownish-yellow, ruptured epidermis conspicuous; paraphyses same as in aecia, but 
-more abundant; urediniospores obovate or obovate-globoid, 15-16 by 16-26%; wall pale- 
yellow, thin, 1-1.5 4, finely and closely verrucose, pores.very indistinct, 6-8, scattered. 
III. Telia caulicolous, elongate and coalescing to form areas 10 mm. long, early 
naked, pulverulent, chestnut-brown, ruptured epidermis conspicuous; paraphyses as in 
uredinia; teliospores elliptical, 36-45 by 50-60%, rounded at both ends, not constricted at 
septa; wall laminate, inner layer chestnut-brown, evenly thick, 2.5-44, pores 4 in each 
cell, lateral, outer layer pale amber-color, gelatinous, 3-7 » thick in water, strongly and 
evenly verrucose; pedicel as long as the spore, near the spore solid, pale-yellow, 7-10 u 
thick, remainder of pedicel thin-walled, colorless and deciduous.

Cycle of development includes pycnia, uredinia and telia; autoecious. Pycnia sub- 
cuticular, other sori subepidermal. 
Pycnia conoidal; hymenium flat ; ostiolar filaments usually present.
