In 1845 Leveille 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 x 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 records it from Brazil, Spruce, but I think it has not been collected in recent years. Our figure 826 is from specimens in Montagne's herbarium, and these are three times as long as the specimen Montagne pictures. I saw no such short specimens. Patouillard has given a detailed account of the structure of the plant. The perithecia are arranged in a circle neat the apex of the stroma. The spores are spindle shaped (rather than caudate, as Montagne shows them) and 25 to 35 mic long. Patouillard claims that Hypoxylon melanaspis has same spores and structure, and is the pulvinate form of Camillea Leprieurii. It does not seem possible to me, but I can not say to the contrary. CAMILLEA BACILLUM (Fig. 827).--Stroma cylindrical, black, 1 cm. long, 1 mm. thick. Apex truncate, shown punctulate in Montagne's drawing. Spores dark, reniform. [Illustration: #Fig. 827.#] This is very similar to the preceding in shape, but is a much smaller species with different spores (teste Montagne). We have only seen the originals in Montagne's herbarium, from which our figure is made. The drawing given by Montagne represents the plant better than our photograph. Montagne records the species from Cuba and French Guiana. We think it a very rare plant.
