Stemonitis Morgani, Peck.
Sporangia crowded, stipitate, springing from a well-developed
hypothallus; cylindrical, wall evanescent; stem much shorter
than sporangium, black, shining; mass of spores hroion with a
femiginous tinge; columella evanescent just below the apex of
the sporangium; threads of capillitium forming the network
brown, snb-eqtial, about 3 g thick, meshes large, and about equal
in size at every part, spores globose smooth, 6—7 g diameter.

On bark, wood, &c. United States.
Agreeing in the large meshed capillitium with S. Carlylei
and S. maxima; differing from the former in the much smaller
spores, and from the latter in the brown or sub-ferruginous
colour of the spores in the mass.
§ § Spores loartecl.
Stemonitis pulehella, Bab.
Scattered or gregarious, springing from a delicate hypothallus ;
sporangio cylindrical or cylindrical-ovate, apex obtuse, base
usually slightly umbilicate, wall delicate, silvery or d a rk ; stem
rather stout, blackish, sub-equal or slightly tapering upwards,
expanded at the base, shorter than sporangium; columella
reaching nearly to the apex of the sporangium; capillitium
dense, threads tapering, arcuate, brown, forming a dense,
irregular net with the peripheral meshes not larger than the
diameter of the spores; spores in the mass clear ferruginous, pale
brown by transmitted light, globose, minutely loarted, 6—8 g
diameter,

On twigs, herbaceous stems, ferns, &c.
Britain (Bardon); Germany.
The peridium is sometimes almost white with a silvery sheen,
at others brown. From 4—6 g high. Much shorter and not
so densely crowded as S. ferruginea. Quite distinct from S.
pidcherrima, B. and C.

Stemonitis herhatica, Peck.
Sporangia densely gregarious, stipitate, springing from a thin
hypothallus, suh-oylindrical, wall evanescent; stem usually
shorter than sporangium, thin, blackish; spores in the mass
brown; columella reaching nearly to apex of sporangium;
capillitium dense, periphercd meshes iiot larger than diameter of
spores, threads sometimes furnished with a few short, free ends;
spores globose, very minutely warted, 8—9 g diameter.

(Authentic specimen from author.)
On living leaves, stems, &c. United States.
Often in scattered, small, densely crowded clusters, 5—8 mm.
hioh. Allied to S. ferruginea in the colour of the spore-mass,
and in the small peripheral meshes of the capillitium, differing
in the very minutely warted spores.

high, orbicular, rarely sub-oblong, basal membrane stout, silvery,
pellucid, iridescent, easily removable from the substratum;
