Family I I I . CONIOMYCETES
Spores either solitary or concatenate, produced on the tips of
generally short threads, which are either naked, or contained in
a perithecium, rarely compacted into a gelatinous mass.—Berh.
Outl. p. 313.
This family is distinguished by the vast predominance of the reproductive
bodies over the rest-of the plant, if not in size, at least in abundance, and from
the ease with which in general they fall from the point of attaohment, in consequence
of which, as the name implies, they have a dusty appearance, and
often soil the fingers of those who handle them. In some oases there is a
decided perithecium or peridmm ; in others there is no approach to such an
organ, and in very nearly allied productions, it may be either present or entirely
absent. Many of the genera are doubtless conditions of higher forms.

Perithecium more or less distinct, free, or erumpent; spores
basal or parietal, simple, or septate, sometimes oozing out by tbe
contraction of tbe peritbecial walls.—Berh. Introd. p. 330.
The structure of a greater part of them is much the same; an obscurely
developed perithecium, minute sporophores, and microscopic spores. I t is
quite certain that a large portion of the so-called species of Phoma, leptos-
troma, Diplodia, Hendenonia, Oytispora, Septoria, &o-, are mere cases of dualism.
All, indeed, are interesting, so far as ascertained dualism is concerned,
or as far as there may be a prospect of showing that they are the
spermatogonia or pyonidia of ascophorous species.-Ji./.-B.
