In dry heathy ground. [Low. Carolina.]
The central substance when yonng is tender and juicy, and consists of
filaments spotted with fertile patches. The filaments of the interstices are
loose, and but little complicated, whereas those of the fructifying spots
are more closely packed, short, and branched, their tips swelling, and
gradually giving rise to large globose utricles, containing the spondia.

Eeceptacle more or less coriaceous or carbonaceous ; disc at
length exposed by the regular or irregular fissure of the outer
coat.—Berh. Outl. p. 372. Intr.p. 283.
The perithecia are elongated, sometimes branched, or, when circular,rather
orbicular than spherical. In the linear species the form of the aperture depends
upon the form of the perithecium,or excipulum,the margins of which
are rounded. In other oases the disc is exposed by the mere fissure of the
walls, as in Pliacidium, and this fissure may either be simple or oompouad,
radiating from a central point, and forming triangular lobes.—Berk. Intr.p.
