This might be made a genus, corresponding to Hypoxylon as to stroma, but having the stroma hollow and filled with a pulverulent mass. In reality, I think it is a better Camillea, the perithecia arranged the same way, not permanent, but broken up at an early stage. Of course, it is only an inference. Leveille states that it has the spores borne on hyphae (acrogenous), but I do not place much value on Leveille's statements. Patouillard, after admitting that he saw nothing but this powdery mass, adds "it is probable that the spores were contained in logettes with fugacious walls, of which only the marks on the inner side of the cavity remain." It would have been better if he had stopped there, but he goes on to propose afterwards that Hypoxylon Bomba should be held distinct from Camillea under the name Phylacia, because it presents a form "stylospored" and a form "ascospored." He does not give the reason for the assertion that it is "stylospored," not even citing the uncertain testimony of Leveille. Phylacia might be held distinct from Camillea on the ground of the powdery mass and the early disappearance of the perithecia and ascus walls. There is nothing new about that. It was done years ago by Fries who called the "genus" Leveilleana, which is a tip for some future name-juggler. All that is really known about its early structure is only from inference, and that inference is contrary to its having been "stylospored."

Fig. 838, a cluster natural size; Fig. 839, broken specimen as often seen; Fig 840, two long stipe specimens.] CAMILLEA SAGRAENA (Figs. 838-840).--Plants oblong about 3-4 mm., stipitate or substipitate at the base, growing densely caespitose, in patches, black, smooth, the apices usually obscurely mammillate. Stipes usually short, but sometimes 6-8 mm. long, and when growing in clusters, the bases consolidated by a carbonous stroma. Interior of the receptacle in two compartments (Fig. 841 x6), the lower filled with soft tissue, black around the edges, but _white_ in the center. The upper compartment filled with a mass of spores mixed with a few fragments of hyphae. Spores narrowly elliptical, 6 x 12, straight, pale colored. [Illustration: #Fig. 841.#]
