18-20 x 8-12 ft, without any appendages but surrounded by a gelati- 

 nous zone, ends subacute. 



On horse dung, Iowa and New Jersey, and on rabbit's dung, Can- 

 ada (Dearness), on decaying potato, Lyndonville, N. Y. (Fairman). 



Winter in Die Pilze makes the spore-bearing part of the asci 

 120-140 x 17-19. The form on potato has asci (p. sp.) 120-134 x 12- 

 15 /x, but in the fimicolous specimens, the asci are shorter. The breadth 

 of the sporidia as given in Journ. My col. is too small. 



S. bombardioides, (Awd.) in literis. 



Hypocopra bombardioides, Sacc. Syll. 847. 

 Exsicc. Rab. F. E. 1527. Rehm. Asc. 233. 



Perithecia superficial, scattered or collected in small, crowded 

 clusters or heaps, very large (| to 1 J mm. high), ovate-oblong or ven- 

 tricose-pyriforni, mostly somewhat contracted below, broadly rounded 

 above and subumbilicate, with a small papilla, of a tolerably firm, waxy- 

 carnose texture, chestnut-brown. Asci clavate-cylindrical, 140-170 x 

 16-18 [x (p. sp.) : paraphyses slender, filiform, jointed. Sporidia 8, ob- 

 liquely, uniseriate, or lying irregularly, elliptical, generally subinequi- 

 lateral, dark brown, with a gelatinous envelope, 22-26 x 12-14/*. 



On horse dung, Mt. Shasta, California (Harkness). 



S. sphaerospora, E. & E. (in Herb.) 



Perithecia densely gregarious, ovate-globose, 250-300 u, covered, 

 but raising the surface of the matrix into little hemispherical promi- 

 nences, from the apices of which project the tubercular-papilliform, 

 obtuse, rough, black, bare ostiola. Asci cylindrical, subsessile, 150- 

 160x18-20 /jl, with very obscure paraphyses. Sporidia uniseriate, 

 obovate-globose, hyaline at first with a broad, gelatinous margin, finally 

 opake and almost black, 20-22x18-20 ji. 



On dung of dogs, Newfield, N. J. 



Outwardly resembles Podospora coprophUa, (Fr.), but sporidia 

 not appendiculate and more nearly globose. 



P0D0SP0RA, Cesati. 



Rabh. Herb. Mycol. No. 259 and in Hedwigia I, p. 103. ' 



Without stroma. Perithecia at first more or less sunk in the 

 matrix, becoming finally more or less free, membranaceous, soft, black 

 of dark brown. Sporidia 1-celled, black or brown, with one .or more 

 appendages, mostly without any gelatinous envelope.
