Extremely common on 
the leaves of evergreens, 
when it is often accom¬ 
panied by Strigula JBahing- 
tonii , and also on the leaves 
of deciduous trees, as the 
Beech, and even on herba¬ 
ceous plants, as Mercurialis 
perennis (Figs. 10&10*). 
Forming little, generally, orbicular tlnil patches, which, 
under a microscope, are setulose. Mycelium sUbgelathioUs, 
readily imbibing water, subhyaline, when young subeontintious; 
when old distinctly moniliform; the articulations elliptic^ 
with one or two nuclei. Peridia dark, setiform, outer coat 
hyaline, the threads at first cylindrical, at length moniliform, 
hyaline, the ultimate joints breaking off; in some states the 
peridia are quite naked. They frequently, but not univer¬ 
sally, spring from a little bulbous base. 
The fruit has not been observed in this species. Its dis¬ 
covery may warrant the formation of the genus Microxiphium , 
Harv. It is scarcely probable that the asci in so narrow a 
space should be of the same nature as in the other species. 
It occurs so frequently with Strigula JBabingtonii , that it has 
been suggested that it bears the same relation to that species 
that Tricharia does to certain epiphyllous lichens. It is, 
however, found without any trace of the lichen, and the 
lichen occurs equally free from the bristly threads. In the 
absence of all information respecting the sporidia, it is im¬ 
possible to come to any certain conclusion : it is, however, 
highly probable that both in Tricharia and our present 
species a great similarity may exist in this respect. The 
specimen on Mercurialis was at first thought distinct, but 
there are no sufficient characters to warrant its being kept 
apart at present. 
We can scarcely suppose that all the species proposed above 
will be retained. The first and three last are, at any rate, 
good species ; it is, perhaps, more doubtful whether all the 
intermediate species are equally good, though the differences 
are sufficiently striking. Were the fruit of all perfectly known, 
we might speak more confidently. 
We conclude our memoir with the notice of a new genus, 
which is abundantly produced in certain situations in South 
Carolina, though the fructification is of rare occurrence. It 
is generally, if not always, accompanied by a new species of 
Myriangium , but lias not the slightest connection with it. 
The threads are cylindrical, inarticulate, fasciculate, creeping 
widely over the matrix, of a shining black ; giving off branches 
from the fascicles, which are themselves fasciculate, and often 
confluent with one another. These are at times contained in 
a common sheath, exactly as in the genus Microcoleus. They 
are for the most part barren, but occasionally fructification is 
produced on the edge of the fascicles, on the free-branched 
apices of the threads. It consists of large, globose, dark 
spores, which contain a single nucleus ; from which circum¬ 
stance we have called it Glenospora. It is analogous to Acre- 
monium , but that belongs to the group 
of 3£iicedinece, while this belongs to 
Dematia —resembling closely the muce- 
dinous genus Prachycarphimn, Berk., 
discovered in amber by Dr. Thomas, 
and figured in the “ Annals of Natural 
History” for December, 1848.
