The characters of the genus cannot be given better than in 
the words of Dr. Montagne, which are, however, very slightly 
modified, in consequence of our having had more objects for 
Forming cloth-like scattered patches, which, at a certain 
period of growth, are separable from the surface of the leaf on 
which they grow. Elocci, connected with one another by their 
comparison : — j thick transparent subgelatinous coat, running here and there, 
Peridium crassiusculum polymorphum, lageniforme clava- as in all the species, into a continuous cellular stratum, where 
turn aut ceranoideum, simplex aut ramosum, e duplici strata closely pressed to the matrix. Peridia mostly simple, but 
formatum, exteriori scilicet e mycelii floccis adscendente com- sometimes forked or even trifid, lageniform, more or less 
pacto celluloso, cellulis deorsum penta-hexagonis, sursum 
parallelogrammis linearibusque, floccorum apicibus soepe 
liberis ciharibus, interiori mucilagineo subliyalino fere anliisto, 
apice irregulariter rumpens interdum ore fimbriatum. Nucleus 
gelatinosus. Sporidia oblonga varie septata fuscescentia ascis 
late obovoideis vel clavatis mox diflluenti-resorptis inclusa. 
Mycelium superficial libere evolutum nigrescens e floccis 
brevibus ramosis monihformibus aut cyhndricis articulatis 
fuscis dense intricatis compositum. 
Hab. In Australia, America boreali a Provincia Ohiensi 
ad Carolinam Inferiorem, Gallia, Britannia atque Hibernia.

parent COAT.

busque ostioliformibus exasperatis; sporidiis minoribus.

surface. Ohio ; T. G. Lea, Esq. On leaves of various plants,

pointed, rough all over with the free ends of the flocci, which 
are often very thick where they spring from their surface, and 
with ostioliform processes, which are in fact abortive peridia. 
Sporidia minute, elliptic, with an occasional septum. Possibly 
perfectly developed sporidia may not have been seen. This 
species approaches so near to Scorias in structure that we 
have placed it in a separate section. It is thicker than the 
others, and more gelatinous, though looking very different 
from the intricate, highly-developed Scorias , which is some¬ 
times an inch or more in thickness. 
* * Elocci distinct, peridia more or less branched 
2. C. Schweinitzii, Berk, and Desm. Velutinum; floccis 
subcylindricis; peridiis subsimplicibus elongatis laivibus; 
sporidiis obovatis cellulosis ; cellulis vix constrictis. FematiUm

The authentic specimen in Sir W. J. Hooker’s “ Herbarium ” 
is'in a very bad state; but it seems to be quite different from 
the plant sent by the late Mr. Lea, which is evidently the 
species of Eries, from Iris description: “ Eibras monstravit 
rudes atras subreticulatas e pluribus con 
glutinatis, ut videbatur, formatas.” The 
peridia are not rough with flocci or 
processes, and, as far as has been seen, are 
simple, though doubtless occasionally 
branched (fig. 3).

Ficr. 2. Capnodium Fuligo. B. anclD. Feridia, mycelium, and sporidia highly mag¬

Flocci of mycelium and sporidia, both highly 
magnified. 
The flocci, too, are far more cylindrical. 
The sporidia are different from those of 
the three following species, which come 
noarest to it in habit and character. 
We do not doubt that we shall soon 
obtain better specimens from Mr. Curtis, 
now his attention has been called to the 
genus. Schweinitz’s Fematium Fuligo 
comprised, probably, several species; 
in his later and larger list he con¬ 
sidered it the same with Cladosporum 
Fumago , Lk., which is clearly a mistake, 
and shows that he had not any definite 
notions as to his species.
