1846, p. 274 = E a; cipula graminum, Berk. Br. Fung. no. 328. A 

 second species of this genus occurs in South Carolina. 



Myxormia, n. g. 



Perithecium tenue excipuliforme apertum e cellulis elongatis 

 compactum. Sporophorse tenerse. Sporse oblongse concatenatse 

 demum liberse, muco involutse. 



447. M. atroviridis. On dead leaves of grass, Batheaston, 

 Dec. 1849. 



Perithecia excipuliform, scattered, minute, quite smooth, 

 formed of long closely -packed narrow cells. Sporophores fili- 

 form. Spores linear-oblong, concatenated, connected by a very 

 delicate thread which frequently breaks off with them, contain- 

 ing one or more globose nuclei, generally one at either end, in- 

 volved in gelatine forming a black green mass resembling 

 strongly the fructifying stratum in the genus Phallus. 



Closely resembling externally Myrothecium gramineumy Lib., 

 but differing greatly in structure. The genus is allied to Exci- 

 pula, but separated from it by habit, by the absence of flocci, and 

 above all by its concatenate spores. The spores collectively are 

 very gelatinous. We do not observe any distinct gelatinous coat 

 to each spore, but infer the presence of a gelatinous medium from 

 the extreme tenacity of the fructifying mass. The genus appears 

 to be allied to Catinula, Lev. 



Plate XIL fig. 9. a. Plant nat. size; h. ditto magnified; c. portion 

 highly magnified, showing the sporo])hores springing both from the walls 

 and cellular base ; d. spores magnified 340 diameters. 



Cystotricha, n. g. 



Perithecium rima longitudinali dehiscens. Sporophorae ra- 

 mosse articulatse submoniliformes hie illic sporis oblongis uni- 

 septatis obsitse. 



448. C. striola. On decorticated wood, Batheaston. Probably 

 very common. 



Perithecia punctiform or linear, often forming little rows, 

 black, with a reddish tinge, opening by a longitudinal fissure. 

 Disc reddish. Sporophores highly developed, greatly elongated, 

 bearing'one or~two branches above, articulate from the base sub- 

 moniliform, the articulations about as long as broad, giving off 

 here and there oblong pellucid spores, which are at first simple, 

 but at length uniseptate. 



This curious little plant has nearly the structure of Tube7'cu- 

 laria, with the addition of a perithecium, the sporophores 

 however being closely articulate. It resembles very much 

 Btictis jHiraUcla, which has however distinct asci and sporidia as
