75-100 /i diam. Asci oblong, sessile, 40-60x12 /i, without par- 

 aphyses. Sporidia crowded-biseriate, oblong-elliptical, subinequilat- 

 eral, uniseptate and constricted, yellowish-hyaline, 12-15 x5/z; accom- 

 panied by a Macrosporium and by smaller stylosporiferous perithecia 

 containing elliptical, subfuscous, continuous sporules about 5x2 /x.

S. exiitans, Cke. Texas Fungi, No. 141. 



Spots minute, dark brown. Perithecia few, immersed, at length 

 casting off the cuticle above them in little operculoid disks. Asci 

 clavate-cylindrical. Sporidia elongated-elliptical, unequally unisep- 

 tate, hyaline, 12x4/2. 



On the upper surface of leaves of Persea Carolinensis, Texas. 



Our specc. of this species from Ravenel are sterile or immature.

Exsicc. EH. N. A. F. 794. 



" Hypophyllous. Perithecia semiimmersed, black, crowded in 

 suborbicular patches. Asci cylindrical. Sporidia narrow-elliptical, 

 uniseptate, 10x2| pj* 



On leaves of Primus Lauro-cerasus, Carolina. 



The specimens sent by Ravenel and issued in N. A. F. 794, seem 

 to be immature, and show no asci, though there are plenty of oblong, 

 12 x 2 1 /jl spores (stylospores)? The perithecia are 100 p diam., scat- 

 tered and amphigenous. 



S. platanif'olia, Cke. 1. c. p. 106. 



F,xsicc. Rav. F. Am. 756. 



Hypophyllous, scattered. Perithecia small (70-80 p), black, glo- 

 bose, perforated, semiimmersed. Asci oblong-cylindrical ("clavate," 

 Cke.), sessile, 22-25 x 6 //. Sporidia biseriate, hyaline, oblong-clavate, 

 6-7 x 2 J p (*' subelliptical, 8x4 p," Cke.)

S. Platani, E. & M. Am. Nat. Jan. 1885, p. 77. 



On round (2-4 mm.), reddish-brown spots with a narrow, dark, 

 slightly raised border. Perithecia epiphyllous, innate-erumpent, 90- 

 120 p diam. Asci oblong, 8-spored, 40-60 x 12-15 /*, nearly sessile. 

 Sporidia biseriate, subhyaline, ovate-oblong, uniseptate and constricted, 

 nucleate, 14-16x4-6 p. Quite distinct from S. platanifolia, Cke. 

 There is a Phyllosticta on the same spots. Perithecia 100 p diam. 

 Sporules oblong-elliptical, 5-6x2|-3 p.
