THE GENUS CAMILLEA.
The receipt of a nice specimen of Camillea Cyclops from Rev. Torrend,
Brazil, has induced us to work over the similar species in our collection.
On our last visit to Europe we photographed the various specimens we
found in the museums, but did not study them as to structure. However,
they make such characteristic photographs that we believe the known
species can be determined from our figures.
We are all familiar with the common Hypoxylons that form little
globose, black balls, usually on dead limbs, in our own woods. They
have a solid carbonous interior with the perithecia imbedded near the
surface. There have been over two hundred alleged Hypoxylons, mostly
from the tropics. We have never worked them over, but suspect that a
number of them from the tropics, when examined, will be found to be
Camilleas. If the specimens were examined, no doubt "prior" specific
names would be found for several of this list.[1]
In the old days all similar carbonous fungi were called Sphaeria.
Montagne first received a section of Sphaeria with cylindrical form,
from South America. The perithecia were long, cylindrical, and were
arranged in a circle or were contiguous, near the summit of the stroma.
He proposed to call it Bacillaria, as a section of Sphaeria, but the
name being preoccupied, he, at the suggestion of Fries, afterwards
named it in honor of himself, Camillea, Montagne's first name being
Camille.
The original species were separated into a genus by Montagne in 1855,
and five species listed, and it is a curious fact that these five species, as
well as all others that have since been added, are of the American
tropics. I have not worked over the "Hypoxylons" in the museums, but
as far as the records go the genus Camillea does not occur in other
tropical countries.

In 1845 Léveillé announced that he had discovered a plant resembling
an Hypoxylon which had, however, the spores borne on filaments
(acrogenous), and not in perithecia. He called it Phylacia globosa, and
classified it in Sphaerioidaea. The specimen (Fig. 847) is still at Paris.
Saccardo has omitted it, and states that Phylacia is probably a
pycnidial condition of Hypoxylon turbinatum. Both were guesses, one
statement surely, and both probably, wrong. The interior is filled with a
powder that under the microscope appears to be made up of ligneous
filaments mixed with a few spores. These filaments appear to me to be
the disintegrated walls of the perithecia, and not the "filaments that
bear the spores." From analogy, at any rate, the spores of all these
similar species are probably borne in asci which disappear early, and
Phylacia seems to be the same genus as Camillea, the walls of the
perlthecla disintegrating and forming a powdery mass. If this view is
correct, Camillea can be divided into two sections.
#EUCAMILLEA.#--Perithecia persistent.
#PHYLACIA.#--Perithecia early disintegrated.
SECTION 1. EUCAMILLEA.
CAMILLEA LEPRIEURII (Fig. 826).--Carbonous, black, cylindrical,
2-3 cm. long, 3-4 mm. thick. Apex truncate, excavate. Perithecia linear,
near apex of stroma. Asci (teste Montagne) linear, 8 spored. Spores
(pale) spindle shape, dark, 6-7 × 25-35 mic.
[Illustration: #Fig. 826.#]
A most peculiar and apparently a rare species. All the specimens I have
noted came to Montagne from Leprieur, French Guiana. Berkeley
