granules. Stipes long, erect or curved,
simple or usually fasciculate and often connate, arising from a thin
hypothallus. Mass of spores and capillitium from reddish-brown to yellow
and ochraceous; elaters simple, rarely branched, 4-5 mic. thick, with
very long tapering extremities, ending in smooth points 8-12 mic. long;
spirals, three or four, perfectly smooth. Spores globose, minutely
warted, 10-12 mic. in diameter.

Growing on old wood. Sporangia with the stipe 2-4 mm. in height, the
sporangium .6-.8 mm. in diameter, the stipe usually longer than the
sporangium. The color quite variable, mostly dull red-brown or
blackish-brown, more rarely yellow or coffee-brown, usually opaque,
rarely shining.

2. TRICHIA FALLAX, Pers. Sporangium obovoid to pyriform or turbinate,
rarely clavate, stipitate; the wall thin, smooth and shining, colored as
the spores and capillitium. Stipe more or less elongated, simple, erect,
brownish below, filled with roundish vesicles. Mass of capillitium and
spores yellowish, ochraceous or olivaceous; elaters simple or sometimes
with several branches, 4-6 mic. thick in the middle, tapering gradually
to each extremity, ending in smooth tapering points, 20-40 mic. in
length; spirals, three, perfectly smooth. Spores globose, minutely
warted, 10-12 mic. in diameter. See Plate I, Fig. 22.

Growing on old wood. Sporangium with the stipe 2-4 mm. in height,
sporangium .6-.8 mm. in diameter, the stipe usually longer than the
sporangium. Under high magnifying power the spores are seen to be
minutely reticulated.

_b. Elaters cylindric, ending in a smooth tapering point._

3. TRICHIA SUBFUSCA, Rex. Sporangium globose, rarely globose-turbinate,
stipitate; the wall thickish, dull tawny-brown above, shading to dark
brown at the base. Stipe simple, erect, brown or blackish in color. Mass
of capillitium and spores bright yellow; elaters simple, rarely
branched, cylindric, 3.5-4 mic. in thickness, ending in smooth tapering
points, 10-12 mic. in length; spirals, four in number, perfectly smooth.
Spores globose, minutely warted, 11.5-12.5 mic. in diameter.

On old wood and bark, Adirondack Mountains, New York. Dr. George A. Rex.
Sporangium .5-.8 mm. in diameter, the stipe equal in height to the
diameter of the sporangium.

4. TRICHIA ERECTA, Rex. Sporangium globose to globose-turbinate,
stipitate; the wall of both sporangium and stipe with a rough outer
layer of brown scales and granules, which, on the uppe
