Outline of group of peridia and sporidia 
highly magnified. 
Fig. 6. Capnodium Persoonii , B. and D. The peridium is in this case rup¬ 
tured horizontally, but this is by no means constant. The endochromc 
of the joints of the mycelium is frequently bipartite. Portions of the 
mycelium, which have been accidentally detached, are growing on the 
hairs of the matrix. From a sketch by Mr. Broome. 
Stratum distinctly setose; mycelium moniliform; joints 
often oblong and uniseptate; peridia crowded, oblong, or 
lageniform; slightly branched occasionally, but by no means 
constantly; rough, with free filaments ; orifice sometimes fim¬ 
briated. Sporidia imperfectly known. 
6. C. Citri, Berk, and Desm. Sparsum, setosum; peridiis 
elongatis; mycelio ramoso moniliformi pulcherrime reticu- 
lato; sporidiis oblongis minutis. Fumago Citri , Pers., 
“ Myc. Eur.,” vol. i., p. 10; Turpin, 1. c. 
On leaves of different species of Citrus. France. Persoon, 
Leveille. 
Stratum thin. Peridia elongated, mostly acuminate, 
conical, or lageniform. Mycelium consisting of beautifully 
reticulate branched moniliform threads. Sporidia minute, 
oblong; sometimes attached end to end, as observed in C, 
Fuligo , by Mr. Broome. 
In this species, C. Fuligo , C. elongatum , and C. Persoonii , 
the sporidia start forth on pressure from the tip of the peri¬ 
dium. Asci have not been observed, but the sporidia are 
attached to each other, at least in two of the species, exactly 
as in many Sphcerice of the sub-genus Hypocrea. 
7. C. quercinum , Berk, and Desm. Valde compactum 
crassum; peridiis fasciculatis ramosis, strato exteriori trans¬ 
verse fragili; mycelio parco, articulis vix constrictis. Fumago 
(Polychseton) quercinum. Pers., “ Myc. Eur.,” vol. i., p. 9. 
On the upper side of Oak leaves. Persoon. 
Stratum thick, closely compacted, easily separable from the 
matrix. Peridia fasciculate, lageniform, often branched, espe¬ 
cially towards their apices, the outer coat cracking trans¬ 
versely. Mycelium spai’ing, consisting of continuous scarcely 
constricted threads. Sporidia unknown. 
A very remarkable species, differing very much in its thick 
stratum, which rises half a lino from the matrix, and might 
be compared to a little wool-comb. Persoon had this species 
more especially in view when he proposed his sectional name. 
The ticket attached to the original specimen is as follows :— 
“ Polychcetum. Fumago quercina. “ Mycol. Eur.” 1. Tres* 
rare. Differe beaucoup cles autres especes, et appartient ou a 
un autre genre ou en fait un particulier.” 
8. C. Caroliniense , Berk, and Desm. Sparsum, se¬ 
tosum ; mycelio parco; peridiis laxis ramosis, latera- 
libus elongatis lageniformibus; sporidiis oblongis bi- 
triseptatis. 
On the under side of leaves of Quercus obtusiioba. 
South Carolina, Rev. M. A. Curtis. 
Stratum thinly planted, but rising considerably from 
the matrix, so that the branched peridia are evident to 
the naked eye; mycelium thin; articulations elliptic, 
slightly constricted; peridia elongated, loosely branched, 
the lateral divisions equalling the main divisions iu 
length, and, like them, lageniform (fig. 7). Sporidia 
oblong elliptic, 
bi-triseptate, 
hyaline, possi¬ 
bly immature. 
Capnodium Ca¬ 
roliniense differs 
from the others, 
in having the 
lateral peridia 
quiteas strongly 
developed as the 
mam ones, from 
whence they 
spring. In this 
and C. Persoonii young germinating plants, whether 
from sporidia or germs is doubtful, present a triangular 
or tricuspidate outline, the angles at length being elon¬ 
gated into filaments. 
9. C. expansum , Berk, and Desm. Late expansum 
velutinum; peridiis conicis brevibus connatis ssope fila- 
mentis brevibus liberis moniliformibus obsitis; sporidiis 
tri-septatis oblongis curvulis. “Lea,” No. 248. 
Extremely common in Ohio, on the bark of Acer nigrum , 
which it clothes with a velvety stratum, rendering the trunks 
black. T. G. Lea, Esq. From the “Herbarium” of Sir 
W. J. Hooker. 
Stratum widely expanded, continuous, velvety. Mycelium 
consisting of branched moniliform threads; articulations 
almost globose. Peridia conical, rather obtuse, crowded, con¬ 
nate, short, scarcely branched, rough from the free ends of 
the moniliform threads, which enter into the structure of their 
outer coat. Sporidia oblong, slightly curved, 3-4 septate. 
(Fig. 8.) 
Remarkable for its widely expanded 
stratum and short crowded conical 
peridia. The sporidia possibly have 
not been seen mature. In this species 
a joint of the mycelium sometimes 
swells exactly as in Antennaria. 
10. C. australe , Mont. Ambiens, 
velutinum; peridiis subdichotomis ut- 
plurimum obtusis; mycelio ramoso 
moniliformi, articulis diametro bre- 
vioribus; sporidiis, ellipticis fenes- 
tratis.—“ Drumm.,” No. 192. 
Surrounding the branches of Coni¬ 
fer ce. Swan River. Mr. Drummond. From “Herbarium” 
of Sir W. J. Hooker. 
Fig. 9. — Stratum thick, velvety. Mycelium branched, 
composed of moniliform threads, the articulations of which 
are broader than long, strongly constricted, and containing 
a single nucleus. Peridia more or less dichotomous, obtuse, 
sometimes swelling at the apex and depressed, sometimes
