460 Rev. M.J. Berkeley and Mr. C. E. Broome on British Fungi. 
Forming a thin olive-black stratum, consisting of generally 
quadriarticulate oblong spores growing four together and per- 
fectly connate, each crowned with an articulate seta as long as 
itself. 
This most curious fungus has occurred once only. It is a 
compound Sporidesmium. The quadriaristate bodies may either 
be regarded as made up of four spores or as spores formed of 
four parallel rows of cells, each row being terminated by a bristle. 
They remind one strongly of the achenium of some Composite 
plant.

on some species of Pachnocybe, Milton, Mr. Henderson ; King’s

The spores have the appearance of fascicles of minute peri- 
thecia.

Allied to Sportdesmium. A very curious and distinct produc- 
tion, of which we have specimens from the author.

Possibly the barren state of some well-known fungus. This is 
probably Lepraria ngra, Eng. Bot.

Desm. Ann. d. Sc. Nat. vol. xi. p. 246; Mougeot & Nestler, 
no. 998. 
We have lately met at King’s Cliffe with well-developed spe- 
cimens of this species, which is precisely the plant of Mougeot 
and Nestler. It has exactly the structure of Torula, and cer- 
tainly has not the spores contained within a tube. Corda’s To- 
rula Casei appears to be very different. A variety occurs on rats’ 
dung. The rats had probably been robbing a cheese infested 
with: the mould. The specimens came from “Mr. Henderson. 
463. T. pulvillus, n. s. Czespitibus pulvimaribus ; floccis com- 
pactis rectis ramosis ; articulis oblongis leviter constrictis. On 
dead twigs of oak bursting in little tufts through the bark, Ape- 
thorpe, March 1841. 
Tufts cushion-shaped, half a line broad, compact, black ; flocei 
straight, slightly branched, often suddenly diminishing in size
