18 ERYTHEA. 



Ampliisphaeria nuda, E. & E. 



On outer bark of CeUis ocoidentalis, Eockport, Kansas, 

 Aug., 1893. Bartholomew, No. 1034. 



Perithecia scattered or loosely gregarious, globose or 

 ovate-globose, rough, dull black, |— | mm. diam., only 

 slightly sunk in the bark; ostiolum short-cylindrical or 

 strongly papilliform and soon perforated. Asci clavate- 

 cylindrical, 100—110x15//, short-stipitate, paraphysate, 8- 

 spored. Sporidia obliquely uniseriate or subbiseriate, 

 oblong-elliptical, brown, obtuse, uniseptate, but only slightly 

 or not at all constricted, 15 — 18x6 — 8/^. 



Differs from A. Spegazziniana, Sacc, in its larger peri- 

 thecia not depressed and broader sporidia. 



Trematosphaeria liyalopus, E. & E. 



On outer bark of living Fraxinus viridis, Eockport, Kan- 

 sas, Oct., 1893. Bartholomew, No. 1233. 



Perithecia gregarious or scattered, bases slightly sunk in 

 the bark and often connected by a scanty, thin, black crust, 

 rough, black, hemispherical, |— 1 mm. diam., with short- 

 cylindrical, conic-pointed ostiolum. Asci cylindrical, short- 

 stipitate, paraphysate, 8-spored, p. sp. 90— lOOxlOyW. Sporidia 

 uniseriate, oblong-elliptical, uniseptate, the septum near the 

 lower end, 12— 16x7— 8/t, lower cell hyaline, the other large 

 cell brown and 1— 2-nucleate, ends rounded. It is probable 

 that the brown part of the spore becomes finally 2-septate, 

 making the sporidia 3-septate, but only one septum was 



actually seen. 



This is closely allied to Tr. miclearia, De Not., but that 

 has the sporidia narrower, and hyaline at both ends. 



Teichospora fnlgurata, E & E. 



On weather-beaten wood of a cottonwood tree shivered by 

 lightning, Eockport, Kansas, Sept, 1893. E. Bartholomew, 



No. 1144. 



Perithecia scattered, erumpent-superficial, minute (about 



J mm.), ovate-globose, rough, black. Ostiolum broad- 



papilliform, soon broadly perforated and finally collapsing.
