8 MR. W. PHILLIPS ON THE GENUS VIBRISSEA. 
The drawing is made from the unique specimen in the herbarium of the Rev. M. J. 
Berkeley, presented by him to the Royal Herbarium, Кем. By Ше kindness of Sir 
Joseph Hooker I was permitted to examine the specimen.

9. ViBRISSEA GUERNISACI, Crouan. Апп. des Sc. Nat. 1857, t. iv. Г. Е. 24-26; Flo. Fin. 
p. 46; Phill. & Plow. СтеуШеа, iv. p. 120. 
Exsiccati: Phill. El. Brit. no. 143. 
Minute, lentiform or turbinate, between fleshy and gelatinous; hymenium pallid, 
ochraceous or grey, convex; asci cylindrical, long ; sporidia 8, filiform, hyaline; para- 
physes slender, branched near the clavate summits. 
On dead submerged branches of байх in water. Мау and June. Rare. France, 
Britain. Named after Viscount Guernisac. Plants 1-3 millim. in diameter; sporidia 
-27 millim. long. 
At first it appears on the branches as a small greyish wart with a somewhat paler 
point in the centre. Ina more advanced state it assumes the form of a thick disk, similar 
to Ше apothecia of Lecanora. The hymenium is convex, soft in texture, pallid bluish- 
yellow, margined by the receptacle, which is submembranaceous, and in section cup- 
shaped, bluish-black, adhering by the greater part of its base to the wood. The asci are 
very long and cylindrical, not as figured by M. Crouan in Ann. des Sc. (1. с.). Тһе 
paraphyses are septate, often branched, and clavate at the summits. The sporidia are 
27 millim. long, very slender, and when mature septate. This species presents the 
same phenomenon of projecting the sporidia from the asci as exhibited by У. truncorum. 
10. VIBRISSEA PEZIZOIDES, Lib. 
Gregarious or scattered, sessile or with a very short stout stipes, disciform, concave 
beneath ; hymenium yellow, convex, umbilicate, margin reflexed, incurved beneath ; asci 
cylindrical; sporidia 8, filiform ; paraphyses slender, branched near the summits, which 
are slightly enlarged. 
On dead wood. Plants 1-2 millim. across. Sporidia "23 x "002 millim. 
I am indebted to Dr. Cooke for a specimen of this interesting species, which he derived 
from the herbarium of the late Madame Libert.

11. VIBRISSEA TURBINATA, n.s. Helotium vibrissioides, Pk. in MS. 
Scattered, turbinate ; hymenium plane or convex, ochraceous yellow, margined by the 
thin edge of the receptacle, which is bluish-grey, smooth ; asci cylindrical; sporidia , 
long, filiform ; paraphyses slender, branched near the summit, which is slightly enlarged | 
and brownish. 
On branches of Ash, in watercourse. Shrewsbury, 1876. Plants 4-1 millim. across ;. 
sporidia from 1:35-2 millim. long.
