Differs from H. fiedleri West and H. deeipiens Thiim. in its much 

 larger sporules. 



Hendersonia staphyleae E. & E. Journ. Mycol. I, p. 151. 



On dead twigs of Staphylea trifolia, Wilmington, Del. April, 

 1892. (A. Commons, No. 1939.) 



The following diagnosis of this species is given as supplementary 

 to the brief notice in Journ. Mycol. 



Perithecia evenly scattered, numerous, pustuliform with a flat 

 base, seated on the surface of the inner bark and covered by the 

 blackened epidermis, which is not laciniately ruptured, but merely 

 pierced by the apex of the perithecium. Sporules, oblong-fusoid, 

 pale brown, 3-septate, and slightly constricted at the septa, narrower 

 below with the lower cell hyaline, 12-20 (mostly 15-18) x 4-5//., on 

 basidia about as long as the sporules. 



Differs from H. sarmentorum West in not penetrating the inner 

 bark and in its longer, paler sporules on shorter basidia. The same 

 thing has been sent from Kansas (Kell. and Swingle, 1,237) on 

 Euonymus atropurpureus. 



Stagonospora strictae E. & E. 



On leaves of Carex strida, Rockport, Kansas. Jan., 1892. 

 (Elam Bartholomew.) 



Spots elliptical, dirty white, 3-5x12-2 mm., with a darker 

 border. Perithecia scattered on the spots, sunk in the parenchyma 

 of the leaf, brown, or when dry nearly black, 100-150/;. diam., per- 

 forated above, visible on the upper surface through the thin epidermis. 

 Sporules elliptic-oblong, hyaline, 2-septate and constricted at the 

 septa, 20-30 x 8-10 \>>.. 



The spots are like those of " Phleospora " (Stagonospora) car ids 

 E. & E., but the sporules are different. 

 Stagonospora sclerotioides E. & E. 



On decorticated wood of Ostrya virginica, London, Canada. 

 March, 1892. (J. Dearness.) 



Perithecia subseriate, erumpent-superficial, brownish-black, elon- 

 gated at first, then globose, sometimes subcontinent, about 1 mm. 

 diam.. of horn-like consistence, white inside, seated on indefinite, 

 subelongated spots limited by a narrow, black, circumscribing line 

 Avhich penetrates deeply into the wood. Sporules oblong, hyaline, 

 2-nucleate, 6-7 x \\iu
