T. pulchella 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 JJL diam. ; the spores have a border 1 p. 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 Granada (K. 1196), has 

 elaters 5 /i 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 fj. diam., 

 and is almost identical with de Bary's type of T. affinis in the 

 Strassburg Herbarium both in capillitium and spores.

4. T. persimilis Karst., in Not. Saellsk. pro Fauna et Flora 

 Fenn. Forh. (1868), p. 353. Plasmodium watery-white, in rotten 

 wood. Sporangia globose, crowded, seated on a common mem- 

 branous hypothallus, 0*5 to 0'8 mm. diam., brown or yellow- 

 brown, shining; capillitium and spores in mass yellow or 

 yellow-brown. Capillitium of cylindrical elaters, 4 to 6 ^ 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 /x 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. Jackii 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. persimilis^ is not a constant character.
