Trematosphaeria confertula (Schw. ). 



Sphesria confertula Schw., Syn. N. Am., 1,508. 



Perithecia densely crowded, seated on a felt-like brown subiculum 

 and clotbed below with straight, septate, bristle- like brown hairs, 

 globose, about i mm. diam., finally collapsing to cup-shaped. Asci 

 clavate-eylindrical, stipitate, paraphysate, 8-spored, p. sp. 60-67 x 

 12//. Sporidia biseriate, oblong, slightly curved, hyaline and uni- 

 septate at first, becoming brown and 3-septate but not constricted, 

 18-22x6-7// 



Whether this is the same as Amphisperia conferta Schw., in N. A. 

 P., p. 206, is doubtful. The spec, referred to in Syn. Car. was on 

 bark of Sassafras, and is described as having the perithecia depressed 

 at the apex, while in the Bethlehem spec, here described, they are 

 deeply collapsed. Dr. Cooke who examined a spec, from Carolina, 

 in Herb. Berk., found the sporidia uniseptate, 12 x 4//. Probably 

 the Carolina spec, is a different thing from the Bethlehem spec, 

 though Schweinitz in Syn. N. Am. considers them the same. 



On rotten wood, Bethlehem, Pa. (Schw.). 



Trematosphaeria Schweinitzii E. & E. 



Perithecia gregarious, semiemergent or erumpent-superficial, \-$ 

 mm. diam. , ovate-conical, gradually attenuated above into the conical 

 or short-cylindrical ostiolum, or when erumpent, depressed- globose 

 with tuberculo-papilliform ostiolum, roughish and brownish-black. 

 Asci cylindrical, stipitate, paraphysate, p. sp. about 90 x 8-10,". 

 Sporidia overlapping-uniseriate, fusoid, brown, 3-septate and con- 

 stricted at the middle septum, the end cells attenuated to an obtuse 

 point and a little paler, 19-22 x 5-6//. 



On dead canes of Rabus, Bethlehem, Pa., Schw. (in Herb.), un- 

 der the name of Sphceria rostellata Fr. 



Teichospora tenacella (Fr.). 



Sphceria tenacella Fr., S. M., II. p. 492. 



Perithecia subseriate, semierumpent through longitudinal cracks 

 in the epidermis, subglobose, smooth, about J mm. diam., finally 

 collapsing above. Asci not seen. Sporidia oblong or oblong-ellip- 

 tical, brown, the end cells paler, 3-5 (mostly 3-) septate, with a 

 more or less continuous longitudinal septum, 20-26x10-11//.. In 

 the oblong sporidia there are mostly only the three transverse septa 

 with constrictions at each septum, but in the oblong- elliptical sporidia,
