Journ. Mycol. I, p. 128. 



Perithecia subulate, stylosporiferous at base, and with a medial 

 or subapica! enlargement above, containing the ascigerous nucleus. 

 This latter character will distinguish this genus from Geratostoma. 

 Caliciopsis, Pk. is also closely allied, but is placed by its author among

Perithecia subcylindrical, about \\ mm. high and 100 p thick, 

 only slightly enlarged at base, and containing subglobose, continuous, 

 brown stylospores 3-5 fi diam., or oblong-ovate, 5-10 x 4-5 p. and 2-3- 

 septate. Ascigerous cavity subapical, formed by a gradual, subovate 

 enlargement 150-175 ji diam., in the middle, and closely packed with 

 the oblong-ovate or subelliptical, 8-spored asci, 12-15 x 7-9 //. on slen- 

 der pedicels 15-20 fi long, and without paraphyses. The asci are hya- 

 line and smaller at first. Sporidia conglomerated, subglobose, brown-

Growing from the inner surface of the loosened bark or from the 

 exposed edges of loosened pieces of bark, on dry, decaying oak limits 

 lying on the ground, Newfield, N. J., Sept., 1877, and March, 1883. 



This description was made from a reexamination of the original

Gregarious, subulate, black and smooth, about 1J mm. high, 115 /t 

 thick, the swollen, subelliptical, ascigerous cavity, about midway be- 

 tween the base and the apex, 250 p. thick. Asci (spore bearing part)

 same length. Sporidia conglomerated, elliptical, hyaline, becoming 

 brown, continuous, 6-7 x 3-3 \ p. 



Ravenel's specimens are on poplar bark. Mr. C. J. Sprague has 

 sent specimens collected by W. N. Suksdorf in Washington, and 

 which agree in all respects with Ravenel's specimens. Suksdorfs 

 specimens are also, apparently, on bark of poplar.
