462 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 
Brockley Combe, Som., Feb. 1845 ; Stapleton, Gloucestershire, 
C. E. Broome and G. H. K. Thwaites, on rotten beech wood. 
Forming a black velvety stratum. Flocci erect, simple, taper- 
ing towards the base. External membrane tough, imarticulate. 
Endochrome breaking up into cylindrical quadriarticulate spores, 
at length escaping from the ruptured thread, each joint having 
frequently a single nucleus. 
A most curious genus, which has also been found near Paris 
by Dr. Roussel. It is accompanied both in the French and 
English specimens by a species of Helminthosporium. 
The affinities of this plant are clearly with Torula, the circum- 
stance of the endosporous mode of fructification being apparent 
rather than real. The outer membrane is very tough, and does 
not break up into separate portions with the spores. The plant 
is in fact a Septonema inclosed in an additional membrane. There 
is occasionally a second inarticulate membrane, a structure call- 
ing strongly to mind some Scytonemata. The conidia of Gra- 
phium penicillatum are produced in the same way. See Bot. Zeit. 
1847, t. 4. fig. 4. It should be mentioned that Dr. Montagne 
had independently of ourselves formed a new genus for this 
plant, which however he has waved in favour of the name given, 
though certainly without any sufficient character, in the Gar- 
deners’ Chronicle.

sporis brevibus articulis depressis constrictis, quandoque subdi- 
visis. Berk. in Gard. Fl. Forfars. p. 296. On leaves of Sedum 
Rhodiola, Glen Callater, July 1844, Mr. W. Gardiner. 
Spots orbicular, traversed by the central nerve, brown. Sori 
minute, crowded. Spores shortly pedicellate, articulations de- 
pressed, sometimes spuriously subdivided, showing a tendency to 
the structure of Triphragmium.

We do not see how this differs generically from Puccinia. The
