Tr. peniophora, (Cke.) 



Conisph&rta peniophorct, Cke. Grev. VlII, p. tig. 

 Trematosphceyia peniophora, Sacc. Syll. 3292. 



Perithecia scattered, black, conical, flattened at the base, smooth, 

 Asci ample, clavate. Sporidia fusiform, constricted in the middle and 

 then faintly 3-5-septate, acuminate at each end, brown, 100x14 ^. 



On bark, New York (Gerard). 



The sporidia remain for some time hyaline, with a granular en- 

 dochrome and uniseptate, but at length become pale brown and faint- 

 ly 3-5 septate. 



Tr. subcollapsa, (E. & E.) 



Lophiostoma subcollapsum, E. & E. Journ. Mycol. II, p. 100, 



Perithecia cartiiagino-membranaceous, black, globose, f-1 mm. in 

 diam., buried in the substance of the bark, the epidermis slightly eleva- 

 ted and blackened over them, and pierced by the papilliform ostiolum. 

 which finally collapses. Asci clavate-cylindrical, about 150x12 //, 

 with abundant paraphyses. Sporidia obliquely uniseriate or more or 

 less distinctly biseriate above, oblong-elliptical, 20-26x6-10 /*. or 

 regularly elliptical, 20-22 x 12-15 //, hyaline at first, becoming brown 

 and 3-7-septate, but not constricted at the septa. The sporidia are 

 sometimes a little curved, or at lea,st more prominent on one side. 

 The ostiolum is quite inconspicuous and only slightly prominent. 

 Sometimes one or two of the cells of the sporidia are divided by a 

 longitudinal septum

This evidently belongs more properly in Trematosphceria, on 

 account of the inconspicuous, deciduous ostiolum.

Perithecia scattered or gregarious, at first buried in the matrix, 

 with only the ostiolum projecting, finally erumpent and nearly, but 

 not entirely, superficial, spherical or subspherical, witli a distinct, 

 short-conical, perforated ostiolum, smooth and bare, \-\ mm. diam. 

 Asci cylindrical, stipitate, 8-spored, 1 30-1 50 x 8-9 //. with abundant, 

 filiform paraphyses. Sporidia uniseriate, oblong, rounded at the ends, 

 2-septate, hyaline, 15-20x6-8 ft.
