difficult to conceive, that a fungus figured hy B u l l i a r d ' and
S o w e r b y should have been lost sight of by that excellent author
; and yet I am almost inclined to believe that such has been
the case. Among the Gasteromycetes, it is as singular as the
genus Lophium among the Pyrenomycetes. With the suborder
Physarei it agrees, except in the character “ sporidia floccis
paucis vage intertexta hut, setting this discrepancy aside, it
cannot be referred to Physarum, Leangium, Craterium, Perichcena,
or Licea, the only genera in that suborder which
have a simple peridium. With the suborder Trichiacei it
cannot possibly be united ; and the character of the order Tri-
chodermacei equally excludes it. Nevertheless, the |_white,
opaque linear bodies which penetrate the mass of sporidia, have
some remote affinity with the lamellated structure of some genera
in the latter order. These remarkable bodies (for they
cannot be called filaments) were thus noticed by P e r s o o n :
“ Fila seminifera compacta parietibus arete adnata, pariter ci-
nerea sunt.” It is, however, not correct to say tliey adhere
closely to the peridium, for they are all left behind when the
peridium is removed, and besides, they occur also in the centre
of the sporidia, though not so numerous. Their origin appears
to be at the base.
Under the impression that there are abundant characters
for constituting a distinct genus, I have named it Angiori-
dium.
Besides the few specimens discovered in Scotland, I have
received others from the north of England, found by my friend
W. C. T r e v e l y a n , Esq.
