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.
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.

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.
CAMILLEA MUCRONATA (Fig. 828).—Stroma cylindrical, black, 6 mm. long, 3 mm. thick. Apex with a prominent, mucronate point. Perithecia linear, contiguous, near the apex of the plant. Asci cylindrical. Spores oblong (M.) 3½ to 4 × 10 mic., colored.
