ncolorous above, dark brown below, hollow, _i. e._ filled
with spore-like cells; capillitial mass yellowish or olivaceous yellow,
the elaters perfectly smooth, long fusiform, tapering gradually to the
long, slender taeniate apices, simple or often branched, adorned with
spirals three, which wind evenly but somewhat distantly; spore-mass
olivaceous or ochraceous, spores under the lens, pale, minutely
delicately reticulate, 10-12 mu.

One of our largest and most common species, in form and size resembling
_H. clavata_, but immediately distinguished by its color. The
capillitium is like that of _T. botrytis_, but differs in the more open
sculpture and the longer and smoother unwound tips. The episporic net is
a constant character in all the specimens examined. This feature reminds
of _T. scabra_.

This is, of course, our familiar _T. fallax_ of all authors from Persoon
down. The earliest unmistakable reference to this species is Hedwig, _l.
c._ But Batsch, in 1789, had used the same combination to describe a
real puff-ball, so that Hedwig's name was already a synonym. The
specific name here adopted is next in point of priority, although
Persoon discarded it the year following, substituting _fallax_, because
he had mistaken the genus.

Not rare. New England, Toronto; west to the Black Hills and Washington,
Oregon, California, south to the Carolinas and Kansas; Jalapa, Mexico.

Sporangia more or less closely gregarious, (_a_) simple
globose-turbinate, dull black when dry, when moist generally with a
vinous tinge, 1 mm. in diameter, stipitate. The stipe concolorous,
rigid, erect, simple even, 2-6 mm., or (_b_) multiple, several
sporangia united by their pale brown or reddish-brown, striate, weak,
closely adherent or united stems; hypothallus small or none;
capillitial-mass bright brick-red cut-off from the stem-cavity, such as
may be, and enclosed by a thick, firm opaque peridium, which opens above
in fragmental or petaloid lobes, leaving a cra
