NEW BRITISH FUNGI. 
and not delicate, and flexiions as in P. umhrata. The habit and 
structure is that of the section Sepultaria, and not of Scutellinia. 
The figures given by Sowerby represent the species very well 
except that the disc is hardly so bright. All circumstances con- 
sidered, we feel satisfied that it is most probable this is really the 
missing species. How far this may be regarded as identical with 
the Peziza brunnea, A. and S., may after all remain doubtful ; we 
are prepared to accept it, meanwhile, as the Peziza hybrida of 
Sowerby. 
Peziza (Sclezotinia) sclerotiorum, Lib. 
It is to be regretted that by some error this species has been 
described over again in the Gardeners' Chronicle, under the name 
of Peziza postuma, Berk, and Wils. From a careful examination 
of fresh specimens, we can trace no difference. 
Cenangium phaeospozuxn, CooJce. 
Scattered, erumpent, clove-brown, about 1 mm. diam., shortly 
stipitate, externally rather delicately furfuraceous, attenuated down- 
wards into the darker stem, margin a little incurved, disc nearly of 
the same colour. Asci elongated clavate, sporidia uniseriate, 
smooth, clear brown (-012 X *008 mm.). Paraphyses thick, 
clavate, brown above. 
On sycamore bark. Exeter (P. Parfitt'). 
Hypospila (Iiinospora) vibuzni, Bncknall. 
Epiphylla, sparsa, nigricans. Pseudo-peritheciis convexis, 
subrugosis, folii innatis, prominentibus, astomis, suborbicularibus, 
cellulosis. Ascis cylindraceis, octosporis. Sporidiis stipatis, fili- 
formibus, hyalinis (’IGmm. long). 
On dead leaves of Viburnum lantana, near Bristol (C. Pwc^waZ/). 
Closely allied to Hypospila populina, Fr., and, in the arrange- 
ment of Saccardo, it would be placed with it in the section Ceutho- 
carpon of Linospora.

The chemistry of Fungi is by no means in a satisfactory state. 
Many of the existing statements are rendered doubtful by a bad 
identification of the species. It is also difficult to obtain a suffi- 
cient amount of raw material, and its perishable nature inter- 
poses another obstacle. Beyond this, the research itself is so 
difficult and expensive, and the question of profitable result is so 
remote to ordinary minds, that few qualified chemists have even 
ventured upon the task. This paper offers little that is original on
