NEW FUNGI OF THE JURA. 
N.B. — Apparently scarcely distinct from Peziza cinerea , except 
in its habitat. But I am strongly of opinion that the true Peziza 
cinerea is confined to wood, and bark, and never occurs on herbaceous 
stems. — M. C. C. 
Peziza (Mollisia) Rozei. Q. 
Punctiformi (*03 mm,), gibbosa, lobulata, granulosa, glabra, 
molli, ex aurantio-incarnata roseola. Sporidia ellipsoidea (*005 
mm. long), deinde fusiformi et guttulata. 
In caulibus emortuis, Hellebori foetidi. 
Peziza (Mollisia) succinea. Q. 
Punctiformis, sessilis, succinea (-05--007 mm.), glabra, sub- 
diaphana, cupuloeformis. Ascis subclavatis. Sporidiis linearibus, 
minimis. 
In lignis cariosis. 
Peziza (Hymenoscypha) equisetina. Q. 
Cupula plana (-05-*8 mm.), tenui, tenera, glabra, luteo-alba, 
stipite brevi (‘05 mm.), tenui lutescente, concolore. Hymenio 
luteo, nitidulo. Sporidia bacillari (*005 -’6 mm.). 
In Equiseto limoso. 
Peziza (Hymenoscypha) tenuissima. Q. 
Pusilla, stipitata, albida (01-0-5 mm.) ; stipite tenuissimo, 
glabro. Margine tenuiter hyalino-floccoso. Ascis cylindraceis. 
Sporidiis linearibus, -005--007 X ‘001 mm. Paraphysibus fusi- 
formibus, acutis. 
In foliis, culmisque graminum. 
Epichloe virescens. Q. 
Peritheciis membranaceis, conico-pyriformibus (*1- 2 mm,), 
e citrino-virentibus olivaceis, in tomentulo concolore nidulantibus. 
Nucleo hyalino. Sporidia aciculari, capillari (-05 mm.), multi- 
septata. Acrospermum strowaticum, Cooke in litt. 
Sicut mucedo in Sphaeria moriformi. 
N.B. — From an examination of specimen, I am still of opinion 
that this is an Acrospermum , and by no means an Epichloe , if 
genera are verities, and not mere names. — M. C. C. 
PREPARATIONS OF ALGjE. 
We have referred on a previous occasion to the excellent pre- 
parations of Fungi for the microscope, made by the Rev. J. E. 
Yize. We have now had the opportunity of inspecting a series of 
mountings of Algas, which have been prepared by the same gentle- 
man, and are of opinion that such preparations must prove of great 
service to those who are commencing the study of these groups ; or 
to those who have no leisure for a special study, but still desire to 
acquire some knowledge of the structure of Fungi, Algas, and other 
of the Cryptogamia. It is hardly to be expected that such a series
