Sporangia closely crowded, cylindric or prismatic by mutual pressure,
obovoid, sessile, olivaceous yellow, smooth and shining; the peridium
thin, opening above somewhat stellately, persistent; capillitium golden
yellow, escaping entirely from the peridia, and forming woolly masses
above them, the threads long, even, beautifully sculptured, bearing
spirals about four, usually smooth and connected by light longitudinal
ridges, the apices short tapering, about equal to the width of the
elater, 6-7 mu; spores concolorous, by transmitted light paler, but still
bright yellow, the episporic net conspicuous, the bands narrow and high,
not pitted nor fragmentary, in form irregularly globose, 12-14 mu.
Plasmodium yellow.

A common and beautiful species recognizable at sight, after the peridia
break, by the aggregate capillitium constantly in evidence above the
abandoned vasiform peridia. The figures of Bulliard are unsatisfactory,
although the description he gives and the name he suggests, still
current, may lead us to concede that he had our species before him. The
spores are larger than in _T. persimilis_, and the episporic net
different, the "border" wider. The plasmodium in the latitude of Iowa
not uncommon in woods in June, after emerging passes into fruit in the
laboratory in about forty-eight hours, and the rupture of the peridia
follows presently. The hypothallus is quite distinct, extra-marginal,
and in substance like to the peridial wall.

Not rare. Throughout the northern forests, Maine to Washington and
Oregon, south to Alabama, Louisiana, Mexico.

8. TRICHIA VERRUCOSA _Berk._

1860. _Trichia verrucosa, Fl. Tasm._, II., p. 269.

Sporangia pyriform, or obovoid, shining, ochraceous from the color of
the contents, stipitate, more or less botryoid or connate; stipe twice
the height of the spore-case, reddish brown, simple or consolidated with
others, weak, inclined, or procumbent; hypothallus distinct; spore-mass
ochraceous yellow, the elaters simple, with smooth tapering points, with
spirals three or four, the spores beautifully and strongly reticulate,
after the manner of the spores in the species preceding, with the meshes
