MR. W. PHILLIPS ON THE GENUS VIBRISSEA. 9 
Hemispherical, then expanded, sessile ; hymenium pallid or straw-coloured, externally 
lurid from the scattered black adpressed flocci, margin crenulate ; sporidia filiform. 
On decayed wood, Jedburgh. Plants 2-3 millim. across; sporidia 2:3 millim. long, 
"032 millim. thick. 
* About half a line aeross; at first perfectly globose, often collapsed in the centre, 
but gradually opening and exposing the soft, pallid, sometimes straw-coloured hymenium ; 
asci oblong; sporidia very long and slender, filiform, flexuous, with a row of globose 
nuclei, at length repeatedly septate."— Berk. & Broome, l. с. 
I venture to regard this as more closely allied to the sessile Vibrissee@ than to Peziza. 
I found a plant on hazel twigs near Shrewsbury, which at the time appeared to be an 
undescribed Vibrissea, to which I appended the name F. coronata. On looking over the 
Discomycetes of Mr. Berkeley's splendid herbarium at Sibbertoft, I was struck by the 
striking resemblance of my 7. coronata to his Peziza leptospora, which a more careful 
analysis has proved to be identical. 
Rejected Species. 
VIBRISSEA PERSOONII, Corda, Anleit. p. 97, t. G. f. 66. 3 & 8. 
* Köpfchen gewólbt, roth; Stiel grünlich. 
* An faulenden Baumstócken sie sitzen." — Corda. 
The only character by which this is distinguished from V. truncorum is the greenish 
stem ; but as V. truncorum often possesses a greenish shade in the stem, there remains 
no difference on which we can depend. 
VIBRISSEA PUBESCENS, Rabh. 
I have not been able to discover any description of this species.
