1846, p. 274= Excipula graminum, Berk. Br. Fung. no. 328. A 
second species of this genus occurs in South Carolina. 
Myxormia, n. g. 
Perithectum tenue excipuliforme apertum e cellulis elongatis 
compactum. Sporophore tenerz. Spore oblong concatenate 
demum liberze, muco involute. 
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 gramineum, Lib., 
but differing greatly in structure. The genus is allied to Evei- 
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 fructifymg mass. The genus appears 
to be allied to Catinula, Lév.

highly magnified, showing the sporophores springing both from the walls 
and cellular base ; d. spores magnified 340 diameters. 
CysToTRIcHA, n. g. 
Perithecium rima longitudinali dehiscens. Sporophore ra- 
mos articulates submoniliformes hic illic sporis oblongis uni- 
septatis obsitze. 
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 Tubercu- 
laria, with the addition of a perithecium, the sporophores 
however being closely articulate. It resembles very much 
Stictis parallela, which has however distinct asci and sporidia as
