Norths. My plant is certainly that of Corda, which is distin- 
guished by the echinulate elaters; and it is also exactly the 
same as specimens from Mougeot in Sir W. J. Hooker’s Her- 
barium, marked Trichia rubiformis, Fr. Whether Fries’s plant 
is really distinct, I am unable to say. Corda figures it as 
having smooth elaters.

About 1 line high; stem straight, slender, with generally 
three short obtuse branchlets given off from the same point ; 
occasionally the stem is forked, but in this case I have not 
seen the second division branched. The whole plant is of a 
reddish-gray hue, and is mealy, with little granules and 
flocci.

222. Cephalotrichum curtum, n.s. Sparsum; _ capitulis 
subglobosis, zneo-fuscis; stipite brevi 1—2 septato fusco ; 
floccis apicalibus, ramosis scabriusculis ; sporis globosis. On. 
leaves of Carices, both on the upper and under side, with To- 
rula graminis, on the margin of a pond. Collyweston, Norths. 
Extremely minute. Stem short, brown, even, with 1—2 
septa, very slightly thickened at the base; heads globose or 
sometimes broadly ovate, bronzy-brown; threads springing 
in a little tuft from the top of the stem, forked or ternate, with 
one or two short acute branchlets, slightly scabrous. Spores 
globose, with a small globose nucleus, smooth. Distinguished 
from C. macrocephalum by its smooth spores, articulated 
stem, and scattered habit, in which two latter points it differs © 
also from C. rigescens. C. flavo-virens does not properly be- 
long to the genus.
