bles the next species in
both color and habit. Fructifications two inches or more in length and
half as wide are not infrequent on the lower side of fallen stems in
forests of deciduous trees. The plasmodium is white.

Not uncommon. Maine to Washington, Oregon, Alaska, and south to Missouri
and Arkansas.

Sporangia globose or obovoid or irregularly spherical, shining, golden
yellow to tawny, anon iridescent with metallic lustre, sessile;
hypothallus thin, but usually very distinct; capillitial mass ochraceous
or tawny yellow, the elaters long, even, about 4 mu wide, the spirals
four, more or less spinulose, generally joined by longitudinal ridges,
the apices short, tapering regularly, anon bifurcate; spore-mass
concolorous, spores by transmitted light bright yellow, marked by an
irregular or fragmentary banded reticulation, the bands broad, flat, and
pitted, 10-12 mu. Plasmodium said to be white.

This species, common throughout the northern world, is distinguished
from its congener, the following, not only by the episporic character,
but generally by its different peridium and more sombre colors. It never
shows at maturity the brilliant golden yellow fluff that hangs in masses
about the open and empty vases of _T. favoginea_, a fact not unnoted by
Batsch, and rendering his figure and description so far determinable.

The episporic network shows all degrees of perfection or imperfection,
and the elater also varies somewhat both in the apices and distinctness
of longitudinal striae. The several synonyms listed seem to have taken
origin in a recognition of some of the more pronounced variations. In
any event the American form _T. abrupta_ Cke., with bifid apices,
belongs here, and European specimens seem to show the identity of forms
described by Karsten and De Bary.

Not rare. New England, Canada, New York, Pennsylvania, Ohio, Alabama,
Missouri, and west.
