he sent specimens, in various stages of growth, which have 
enabled the author of this memoir to observe the morphosis, 
and to establish the following points :—1. That what had 
been taken for the pileus of an Agaric in the upper hemi- 
sphere of the peridium, whose lower half surrounds the mid- 
dle of the stem, under the form of a wide volva. 2. That 
the supposed gills are true dissepiments, springing from 
every part of the pileiform portion of the peridium. After a 
due examination of the different parts of which this curious 
Gasteromycete is composed, the author remarks that it is 
impossible to leave it in the place assigned to it by Fries, 
and that it must become the type of a new and very distinct 
genus, to which, from the peculiar conformation of the disse- 
piments, he has given the name of Gyrophragmium. The 
following are its characters: Ae 
Receptaculum stipitatum. Peridium primo turbinatum, 
dein medio orbiculatim ruptum, superne pileiforme, cum sti- 
pite centrali ad apicem usque producto, volvá amplå (quæ 
nihil aliud nisi pars peridii inferior) instructo continuum. Ca- 
pillitium in dissepimenta contextum lamelliformia, subparal- 
lela, è peridii toto hemispheerio descendentia, a stipite distan- 
tia, in plano. ramosa (non autem anastomosantia) sinuosa, 
plicato-crispata adeoque densata ut sibi coherere videantur, 
primo lenta olivacea tandem exavescentia, fragilissima, nigra, 
subtus libera, labyrinthiformia. Flocci liberi nulli. Spore 
globose, pedicellate, dissepimentis affixe. Contextus peridii 
stipitisque fibrosus, in dissepimenta continuatus.— Fungi 
arescentes, persistentes, habitu Agarico aut Boleto similes, 
specie volvati aut annulati, stipitati, in arenosis maritimis 
Africe borealis e£ Galliz australis hucusque obvii. 
The author then compares this genus with Secotium, Kze. 
and Polyplociun, Berk., which have the most resemblance to 
it, and from this pe he deduces the affinities and dif- 
ferences. 
Before this new memoir on the little tribe of Podavinee, 
it was composed of three genera, Cycloderma, Klotzsch;
