462 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



Brockley Combe, Som., Feb. 1845 j 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, inarticulate. 

 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-

 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
