80 EEYTHEA. 



profusely discharging the spores over the leaf. Uredospores 

 broadly elliptical or obovate, 20-25x15-18/^, distinctly echin- 

 ulate at first, nearly hyaline, then smooth and light yellowish, 

 filled with fine granular matter throughout without nucleus. 

 Epispore very thin, — l/i thick. Paraphyses common in some 

 of the sori. Teleutosori abundant, very small, about ^ mm. 

 diam., nearly round, persistently tectate, runniug by conflu- 

 ence into long continuous patches entirely covering large 

 areas of the host. Teleutospores light to dark yellow, cla- 

 vate to oblong, 40-60x15-18/^, lower cell usually wedge- 

 shaped and nearly hyaline; upper cell often terminating in 

 a curved acuminate beak or rounded, or flat on top; nearly 

 all containing either nuclei or fine granular matter. Pedicels 

 stout, hyaline, 10-25// long. Approaches P. angustafa, Pk., 

 but differs from that in its paraphysate uredosori and in its 

 smaller and persistently tectate teleutosori. 



Phoina biformis. On dead Amorpha fruUcosa. Eooks 

 Co., Kan., March 16, 1896 (No. 2057). 



Perithecia scattered on the weather-beaten, decorticated 

 wood, iunate-erumpent, hysterii-form, |-1 mm. long, ovate- 

 conical,^-! mm. diam. Sporules oblong-elliptical, 2-nucleate, 

 hyaline, subobtuse, 6-7x2//. Basidia simple, obclavate 12x2//. 



P. Amorphce, Sacc, has the perithecia globose-lenticular 

 and much smaller with ovate sporules 6-7x4//. 



Cytispora celastrina. On dead stems of Celastrus scan- 

 dens. Rooks Co., Kan., April 5, 1895 (No. 1716). 



Stromata scattered or subseriate, 1-1^ mm. diam., sunk in 

 the inner bark, raising the epidermis into pustules which are 

 soon ruptured, exposing the stout, shortrcylindrical, broadly 

 perforated ostiolum, black inside, multilocular, (8 — 10- 

 celled). Sporules oblong, straight or slightly curved, 6-8x 



Differs from C. Celastri, Clem., in its much shorter, 

 scarcely curved sporules. 



Cytispora (xleditschiae. On dead limbs of Gleditschia 

 triacanthos. Rooks Co., Kan., Dec. 16, 1895 (No. 2011).
