128 BOTANICAL GAZETTE. 



Sheaths and upper surface of leaves of Vilfa. Colorado. In the 

 character of the sori this species resembles Puccinia Graminis, from 

 which, however, it differs in its paler ferruginous-brown color. The 

 mature spores easily separate from the pedicels, in which respect the 

 fungus simulates species of TricJiohasis. 



Uromyces sanguineus. — Spots small, scattered, sometimes conflu- 

 ent, bright-red or purplish-red ; sori scattered, one on each spot, prom- 

 inent, cinnamon-brown, often partly concealed by a single large frag- 

 ment of the ruptured epidermis; spores obovate or oblong-pyriform, 

 .001-.0016 of an inch long, .00065-.0008 broad, generally uninucleate, 

 easily separating from the pedicel ; pedicel hyaline, equal to or less 

 tiian the spore in length. 



Leaves of Berheris AquifoUuvt. Colorado. The deciduous pedicels 

 connect this species with the genus Trichobasis, but I find an occa- 

 sional one that is persistent, which, with the Uromyces-like appear- 

 ance ot the spores, induces me to refer the species to the genus 

 Uromyces. 



Cronartium ComandRuE. — Peridium elongated, subcylindrical, more 

 or less curved, slightly swollen at the base, yellowish or bright or- 

 ange ; spores subglobose, .0003-.0004 of an inch in diameter. 



Stems of Comandra 'pallida. Colorado. A paler form of what ap- 

 pears to be the same species occurs on the leaves of Comandra umhel- 

 lata, but I have not seen it fertile. The fungus surrounds the stems 

 on all sides with its bright-colored bristling peridia. 



^ciDiUM GRACiLENS. — Spots thickened, green or slightly discolored; 

 peridia hypophyllous, elongated, slender, pink or rosy-red, white 

 when evacuated ; spores globose, bright-orange, .0009-.001 of an inch 

 in diameter, with a thick hyaline epispore. 



Leaves of PJiiladelphus mkrophyllus. Colorado. "Not common." 

 The pinkish hue of the peridia when filled with spores is very beauti- 

 ful. 



Some Missouri Ferns. — I have found Asplenium parvidum growing 

 abundantly along the cliffs of the James River in this county (Greene), 

 also Adiantum Cap illus- Veneris in the same locality. — E. M, Shepard,
