[Vol. 8. 
in fact the two are confused in American and European her¬ 
baria. But G. radicans has a silky fimbriate mouth while in G. 
fornicatus the mouth is sulcate-striate. 
In the box sometimes mixed together and sometimes wrapped 
in separate lots were vast numbers of two very small Geasters. 
One has the particles of sand bound to it all over by the mycelium 
and it has a protruding sulcate mouth; this is evidently Geaster 
striatulus Kalch. The other little Geaster roots from the base 
and has a fimbriate mouth. So far as figure and description go 
it is Geaster floriformis Vitt. and has never been noted in this 
country before. 
Most of all however, I prize what I believe to be genuine 
specimens of Geaster fimbriatus Fr., the only ones I have ever 
seen that filled the bill, though I have seen many specimens 
labeled Geaster fimbriatus Fr. It is buried in the ground and 
mycelium issues from the whole outer surface; when it expands 
it carries away a coat of sand or else the sand strips off the cuti¬ 
cle. The most marked feature is, as stated by Fries, “Sporidia 
fuliginosa” ! Fries’ reference to Micheli’s first figure on Tab. 
ioo, however, is erroneous as he himself evidently suspects, in 
parenthesis. This figure of Micheli’s plate applies to what we 
are accustomed to call in this country Geaster triplex Jungh. It 
should be called Geaster stellatus Linn.

The following genus with its type species Acontium album 
I have had on hand for some time. It will be recognized easily 
by its relationship to Cephalosporium. I can furnish a number 
of the specimens of the type to microscopists desiring them. By 
Tiyphasma” I mean the general aspect of the mould to the naked 
eve or with a simple lens; this is different from the sense in which 
Link uses it. 
Acontium Morgan genus nov.— Hyphse decumbent hyaline, 
septate, vaguely branched, the sporiferous branches uniform, as¬ 
cending, each producing at the apex several spores which are 
conglutinate into a pellucid glomerule. Spores simple, cylindric 
or fusiform, smooth, hyaline. 
A genus somewhat resembling Cylindrocephalum, but the 
spores are involved in mucus as in Cephalosporium. 
i. Acontium album Morgan sp. nov.—Hyphasma effused, 
thin,, dense, white, minutely pubescent. Hyphse creeping*, slender, 
hyaline, scarcely septate, intricately much branched; the sporifer-
