. MR. F. CURREY ON BRITISH FUNGI. 159 
view, constricted at the septa, yellow, about 0:0015 inch long, but varying slightly in 
length. On carpels and stems of Triglochin palustre. Near Ringmer, Sussex, Oct. 1862.

CONIOTHECIUM AMENTACEARUM, Corda. 
Some specimens of this fungus which I met with in May of last year (1862) gave me 
a good opportunity of observingits structure. It has been represented by Corda (* Icones 
Fungorum,' vol. i. fig. 26) as forming an amorphous mass of sooty spores; and this is, no 
doubt, the condition in which it is frequently if not most commonly seen, either owing 
to the plant being past its prime or from want of sufficient care in manipulation. If 
examined before the cells become separated from one another, it will be seen to consist 
of stiff continuous threads, formed of rows of cells of very irregular shape. Fig. 1 repre- 
sents a portion (hardly more than one-half) of one of the threads, which, as is usually the 
case, was attached, with erowds;of others, to the apex of the perithecium of some Spheria. 
The lower half of the thread, although traceable to a certain extent, was not sufficiently 
clearly visible to enable me to draw it with the camera lucida; but it did not, I think, 
materially differ from the upper half. I made some remarks on Comiothecium Amenta- 
cearum in the * Philosophical Transactions' for 1857 (p. 548), and figured the sporidia of 
a Spheria to which I had then found it attached, and which I called S. salicina, Pers. 
The sporidia were identical with those of a plant marked S. salicina, Pers., in Sir W. 
Hooker's herbarium. I have since had an opportunity of examining an authentic speci- 
men of S. salicina in Mr. Berkeley’s herbarium, and found the fruit in this latter specimen 
to be simple and sausage-shaped. The fruit of S. salicella, Fr., according to an authentic 
Specimen in Desmaziére's ‘ Plantes Cryptogames de France,’ No. 838, is the same as that 
which I have figured in the ‘ Philosophical Transactions,’ 1857, pl. 25. fig. 19, and in 
the ‘Transactions of the Linnean Society,’ vol. xxii. pl. 48. fig. 149, under the name 
of S. salicina.
