nerally complete and always large, quite variable in size 12-16 mu.

Rostafinski quotes the species (_teste_ Lister) from Chile. Specimens in
the herbarium of the State University of Iowa are from Jalapa, Mexico,
collected by Mr. C. L. Smith. The species may be therefore expected in
the southern United States. Berkeley described it from Tasmania. _T.
superba_ Mass, from description would seen to be the same thing.

9. TRICHIA PULCHELLA _Rex._

1893. _Trichia pulchella_ Rex, _Proc. Phil. Acad._, p. 366.

Sporangia solitary or in groups of four or five, bright vitelline
yellow, sessile; the peridium thin, transparent, opening irregularly
above; hypothallus none; capillitium bright yellow, not emergent, the
threads narrow, 3-4 mu, wound with spirals three or four, more or less
irregular, smooth, longitudinal ridges wanting, the apices rather long,
acuminate, about twice the diameter of the elater, or anon clavate or
even globose, bulbose at the tip and furnished with several stout
spines; spore-mass concolorous; under the lens spores colorless, marked
by a very feebly developed reticulation of _T. persimilis_ type, but the
bands narrow and, as shown by the narrow "border," low, meshes few and
often imperfect, globose or sub-globose, about 12 mu.

The episporic characters of this species ally it to _T. persimilis_ most
nearly. The reticulations are possibly not more divergent from the
typical form of that species than are the same features in some other
forms there included. But in the present case, added to the episporic
sculpture, we must reckon the peculiar capillitial thread, unlike that
seen in either of the chrysospermatous forms, and the gregarious habit
without hypothallus. These peculiarities seemed to Dr. Rex distinctive,
and as they appear constant they may be left to separate the species.
