septate and with one or two of the intermediate cells divided by a 

 longitudinal septum, 15-25x8-12 fi. Quite often asci are seen in 

 which the sporidia are smaller, black and shriveled as if struck with 

 blight before maturity. Closely allied to T. patellarioides, Sacc, but 

 differs in its larger, globose-hemispherical perithecia without any fringe 

 of hyphae at the base, and in its 5-7-septate sporidia uniseriate in 

 narrower asci. 



On decorticated weather-beaten limbs of Salix, Helena, Montana 

 (Kelsey), on wood of Prunus Virginiana, Montana (Anderson). 



Teich. pygmaia, E. & E. Journ. Mycol. IV, p. 63. 



Perithecia scattered, erumpent-superficial, depressed-globose, 

 black, 200-225 [i diam., with a papilliform ostiolum, finally perforated. 

 Asci clavate, 70-80x15-18 //, subsessile, 8-spored, indistinctly par- 

 aphysate. Sporidia irregularly biseriate, ovate-elliptical, mostly 3-sep- 

 tate (exceptionally 5-6-septate), with one or two cells divided by a 

 longitudinal septum, 15-20x6-8 //, pale yellowish-brown. Seems 

 nearly allied to T. pruniforviis, Nyl., but smaller in all its parts and 

 lacks the acute, conical ostiolum.

Teich. taphrina, (Fr.) 



Spharia taphrina, Fr. S. M. II, p. 465. 



Teichospora taphrina, Fckl. Smyb. Nachtr. I, p. 305. 



Perithecia scattered, black, immersed, then emergent, subcom- 

 pressed-elliptical, obtuse, with a simple, perforated ostiolum. Asci 

 cylindrical, substipitate, 8-spored, 88 x 12 // (p. sp.). Sporidia obliquely 

 uniseriate, ovate or oblong ovate, sometimes curved, ends obtuse, 

 generally irregularly 3-septate and muriform, slightly constricted at 

 the septa, brown, 14x7-10 //. Paraphyses filiform, abundant. 



Found on old wood, Bethlehem, Pa. (Schw.). 



Unfortunately, we can not find in the Schweinitzian herbarium 

 any specimen of this species or of T. sendnuda, (Pers.).

Strickeria vilis. Winter, Die Pilze, 3204, Cke. Syn. 3168. 



Perithecia almost microscopical, punctiform, much scattered, 

 smooth, glabrous, opake, emerging from the bleached fibers of the 

 wood, and then almost superficial. Ostiolum very minute, deciduous.
