that the spores are distinct and echinulate, and they are not 
mixed with abortive spores, or if so, in a very slight degree. 
The two species are certainly very nearly allied, but are, I 
believe, distinct.

The following abstract of Dr. Montagne’s memoir, entitled 
* General Observation on the tribe of PonAxiINEJE, and the 
establishment of a new genus Gyrophragmium;" belonging to 
this tribe, will be read with interest in connexion with the 
present memoir, and a former one on Secotium and Polyplo- 
cium. It is extracted from * l'Institut," May 4, 1843. 
After having defined this little group of the order of Tri- 
chogastric Fungi, remarkable especially for the presence of a 
columella due to the elongation of the stem into the peri- 
dium, the author gives the history of the genera which belong 
to it, and a general description, in which the peridium, colu- 
mella, capillitium, and spores are reviewed. The genus 
Montagnea, Fr. (Gener. Hymenomycet, April, 1836, p. 7), of 
which the termination has been since modified (Montagnites, 
Epicrisis, p. 240), is analysed and defined. Of the three 
species admitted into the genus by Fries, Dr. Montagne, 
who communicated two of them, M. Candollei and M. Du- 
nalii to the author, shows that the first only can continue to 
form part of it, inasmuch as the second does not belong to 
. the Agaricinee, but to the family of Gasteromycetes. Dr. 
Montagne forms his new genus, Gyrophragmium, from this. 
species, M. Dunalii, and places it at the bead of the tribe 
Podazinee.  Gyrophragmium Dunalii, found at first with 
Montagnites Candollei, on the shore of Maguelone, near 
Montpellier, received from Prof. Delile the name of Agaricus 
ocreatus. It is, at least, under this name M. Touchy has 
sent it to Montagne, who communicated it to Fries. More 
recently, Capt. Durieu found it again in Algiers, from whence
