MR. F. CURREY ON BRITISH FUNGI. 155 
ıı The cases in which a partial escape of the inner membrane has been observed are to 
be found in Pringsheim's * Jahrbücher für wiss. Bot.’ vol. i. p. 189; ‘Quart. Journ. Micr. 
Science, vol. vii pl. ll. fig. 18; and in Tulasne's ‘Selecta Fungorum Carpologia,’ 
pp. 43, 44. 
PATELLARIA ATRO-VINOSA, Blox. MS. 
Gregarious; dise minute, round or of irregular outline, almost black, distinctly mar- 
gined ; margin of a vinous-purple colour. Sporidia almost colourless, but with a greenish 
tinge, narrowly almond-shaped or curved, with the endochrome tripartite, 0:0009 inch 
long. Gopsal, near Twycross. The Rev. A. Bloxam. 
The above description is from the dried plant. The specimens grow in a densely 
erowded manner, and the difference in colour (in the dried specimens, at least) between 
the dise and the margin is very striking. 
Plate XXV. fig. 31 represents the sporidia highly magnified. 
PATELLARIA AQUATICA, n. 8. 
Dise minute, scarcely a line wide, of a brownish tinge, distinctly margined, usually 
quite round and compact. Sporidia colourless, 1-3-septate, 0:0009 to 00011 inch long. 
The shape of the sporidia varies from (a) (Pl. XXV. fig. 23) when young, to (d) when 
perfect. The excipulum is formed of small distinct brown cells. On dead rushes in 
water. Pond at St. George's Hill, Weybridge, May 1862. I found it also a few days 
afterwards at Paul's Cray Common.

PATELLARIA PALUSTRIS, n. S. 
Dise very dark bluish grey, almost black, margined, round or irregular, nof a line 
wide. Excipulum composed of small, distinctly outlined cells, as in the last species. 
Sporidia colourless, narrowly turbinate, elliptical or curved 0:0004 to 0:0005 inch long. 
On dead rushes in water. Paul's Cray Common, May 31, 1862.

PuacrprUM PINT, A. & S. à 
I have been much struck by the beauty of the fruit of this well-known species of 
Phacidium ; and as I am not aware that it has been drawn, I have given a figure of it. 
The sporidia are colourless, very long, multiseptate, often tape ring me ope end ton 
the other, each extremity being extended into a filiform prolongation. ; 
Plate XXV. fig. 36 represents a sporidium, x 490; fig. 13 represents the fruit of 
` Phacidium lacerum, Fr., x 220; and fig. 7 that of P. coronatum, X 430. 
I think it not improbable that in both these latter species the fruit, when more ad- 
vanced, may become septate; possibly after the escape of the sporidia from the ascus.
