218. Trichia Neesiana, Corda, fasc. 2. f. 288. Apethorpe, 

 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, aeneo-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 7b- 

 rula graminis, on the margin of a pond. Colly weston, 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. Dist inguished 

 from C. macro cephalum 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.
