Elevating the barb, which is at length ruptured by the evolution of the
perithecia, which are at first included in a receptacle, but having pierced its
surface, assume a globular form, and appear as if merely seated on that
body, others push aside those which preceded them, and thus irregular
clusters are produced. When it occurs it is in great abundance, frequently
covering the smaller branches for many feet, at intervals often not exceeding
the eighth of an inch.—Grev.

Gregarious, scattered or crowded, perithecia pale-ochre, with a minute
papillæform orifice more or less collapsed when dry. Formerly considered
as a state of N . coccinea, from which the clavate asci and longer sporidia distinguish
it.

Mycelium forming white lanose patches, 2 in. or more in diameter, and
