On an old broom, Albany, N. Y. (Peck). 



This< species is closely allied to Ch. elatum, but much smaller and 

 neater. It is wholly black and without the fibrous base of Ch. elatum. 

 The hairs are more delicate and not half the diameter, and the sporidia 

 are scarcely more than half as long and broad. 



Oh. inelioloides, C. & P. 27th Rep. N. Y. State Mus. p. 106. 



Perithecia scattered, minute, brown, globose, arising from a 

 branching, septate mycelium. Bristles black, rough, two or three 

 times dichotomously branched above, the branches spreading. Sporidia 

 ovoid or subglobose, pale brown, 4^5x3-3| /i. 



On culms of Zea Mays, New York, New Jersey and Louisiana. 



Differs from Ch. funicoliiin principally in its more branching 

 hairs which cover the perithecia about uniformly above and below. 



FAMILY. SORDARIEj;. 



Perithecia either superficial or sunk in the matrix, with theij' upper 

 part more or less projecting or sometimes erumpent, without (or more 

 seldom) with a stroma, in which, when present, they are irnmersed; 

 of soft, watery substance, brown or black, often translucent, with a 

 decided round ostiolum. Asci generally witli the apical membrane 

 strongly thickened; paraphj'ses present. Sjiovidia dark colored, one 

 or more-celled. 



Mostly coprophilous ; short Ii\-ed in comparison ^\•\\h the liosel- 

 Ihiius and othcM' similar forms from which they are also distinguished

Without stroma. Peritliecia immersed, often finally erumpent 

 and free, or superficial from the first, membranaceous, soft, black. 

 Sporidia one-celled, lirown or black, without appendages but sur-
