T. jndchella Rex differs from the usual developments of T. affinis 
in the more scattered habit of growth of the sporangia ; the elaters 
are narrow, being 3"5 to 4'5 \x diam. ; the spores have a border 1 /x wide 
and are reticulated with narrow, minutely pitted raised bands, pre- 
senting from three to four meshes on the hemisphere ; it can hardly 
be considered as having distinctive specific characters. The type 
specimen of T. Kalbreyeri Mass., from New G-ranada (K. 1196), has 
elaters 5 diam., with delicate longitudinal striae, and spores marked 
with a rather close reticulation of broad, faintly pitted bands ; it 
does not appear to differ from typical T. affinis. The type specimen 
of T. intermedia Mass. from Scarborough has elaters 4 to 6 /x diam., 
and is almost identical with de Bary's type of T. affinis in the 
Strassburg Herbarium both in capillitium and spores.

brown, shining; capillitium and spores in mass yellow or 
yellow-brown. Capillitium of cylindrical elaters, 4 to 6 /a diam., 
marked with about four closely set spiral bands, usually beset 
with numerous short slender spines; the ends of the elaters 
conical, acute, or with the spiral bands produced at the apex 
into two or three diverging points; longitudinal striae incon- 
spicuous. Spores yellow, or yellow-brown, 11 to 14 yu, diam., with 
the reticulation broken, or represented by irregular pitted warts, 
border interrupted. — Trichia Jackii Rost., Mon., p. 258 (1875) ;

A type specimen from Finland, from Dr. Karsten, agrees essentially 
with the examples of T. JacJcH Rost. in Strassb. Herb. ; the latter 
name must therefore be dropped as being antedated. The occurrence 
of the long spinous processes on the elaters, noted in the original 
description of T. jiersimilis, is not a constant character.
