Macbride: “Sporangia scattered or crowded upon a hypothal- 
lus more or less distinct, globose or ellipsoidal, short-stipitate, 
varying somewhat in color, at first rosy or flesh-colored, later 
brownish or ocliraceous; the peridium exceedingly thin, pellucid, 
mealy, evanescent above, persisting as a shallow cup below, capil- 
litium inelastic, rather closely netted of threads variable in thick¬ 
ness, marked by frequent thickenings or expansions, everywhere 
warted, attached to the peridial wall; spores in mass flesh-colored, 
under the lens colorless, smooth, globose, 7.5-9/a. When newly 
formed the sporangia have a peculiar rosy or flesh-colored metal¬ 
lic tint, which is all their own. Within a short time this color 
passes, and most of the material comes from the field brownish 
or ochraceous in color. Typical sporangia are spherical on dis¬ 
tinct short stipes. The capillitium never expands as in Ar- 
cyria.” 
Saccardo makes the diameter of some of the capillitium nodes 
10/a, the thread 3-5/a thick, and the spores 6.5-7.5u in diameter. 
My specimens have about the same habit of growth and the 
same size of sporangia as Trichia persimilis, T. scabra, and 1. 
favoginea. From the color when old this species might be mis¬ 
taken for T. persimilis. The sporangia are sometimes pear-shaped 
with the smaller end uppermost. There is a thin, papery hypo- 
thallus. The most distinctive feature in the general appearance of 
this species is the non-elastic capillitium-mass, and its gradual 
disappearance as the peridium wears away, leaving the tops of the 
sporangia with their capillitium and spore-mass always clean-cut 
and level. The capillitium-thread is very unequal in width, with 
frequent enlarged nodes, and with small and large loops and 
rings formed in the thread. The spores are smooth, colorless, 
6-9/a in diameter. 
One specimen was found at Lake Mills, November 1901, an¬ 
other in the cemetery woods, October 29, 1903, both growing on 
dead poplar wood; another on dead wood in the cemetery woods, 
October 21, 1903; one at Eagle Heights October 2, 1912, also on 
wood: another on dead wood at Eagle Heights, October 21, 1904.
