2. T. verrucosa Berk., in Hook., Fl. Tasm., ii., p. 269 (1860). 

 Plasmodium ? Total height 2 to 4 mm. Sporangia pyriform or 

 clavate, stipitate, clustered or solitary, 1'4 nirn. high, 0'8 mm. 

 broad, ochraceous-yellow, mass of elaters and spores golden- 

 yellow ; sporangium-wall membranous, minutely and closely 

 papillose, pale yellow. Stalks membranous, 1 to 2 mm. high, 

 usually combined in clusters of three or four, rugose, yellow- 

 brown, or dark brown. Capillitium of long cylindrical elaters, 

 4 to 6 /A wide, with short conical ends, marked with three to five 

 narrow spiral bands, smooth, or with a few scattered spines, longi- 

 tudinal striae distinct. Spores reticulated with narrow, minutely 

 pitted bands, forming a network with about seven meshes to the 

 hemisphere, 13 to 16 ^ diam., border 1 /x wide. Mass., Mon., 

 p. 191. T. superba Mass., in Journ. R. Micr. Soc. (1889), p. 345;

The specimen from Tasmania (K. 1750) described by Berkeley as 

 T. vermcosa is somewhat immature, but is sufficiently developed to 

 be clearly identified as the same species as T. superba Mass, from New 

 Zealand. A fine specimen of the same form from Chili, in the 

 Strassburg Herb., is named by Rostafinski T. chrysosperma. It is no 

 doubt closely allied to that species, but the constancy of the characters 

 of the stalked sporangia and of the spores marked with a rather close 

 reticulation of narrow bands forming a border scarcely 1 p. broad 

 supports the specific distinction. A large gathering by Prof. Balfour 

 in Scotland shows the same characters. 



Hab. On dead wood. Moffat, Scotland (L:B.M.134) ; Tasmania 

 (K. 1750, 1751); New Zealand (K. 1166, 1167, 1764); Chili (Strassb. 

 Herb.). 



3. T. affinis de Bary, in Fuckel, Symb. Myc., p. 336 (1869). 

 Plasmodium watery-white, in dead wood. Sporangia globose, 

 sessile, crowded on a membranous hypothallus, 0'6 to 1 mm. 

 diam., shining golden or ochraceous-yellow; mass of elaters and 

 spores bright yellow ; sporangium -wall membranous, pale yellow, 

 marked with delicate irregular striae. Capillitium of long cylindrical 

 elaters, 4 to 6 /x diam., with conical pointed ends, marked with 

 four to five spiral bands, smooth, or with minute scattered spines ; 

 longitudinal striae usually present, but often faint. Spores reti- 

 culated with broad, rarely narrow, pitted bands, forming a more or 

 less complete net with three to five meshes to the hemisphere, 13 

 to 15 /xdiam., border 0'5to 1 /x wide. Host., Mon., p. 257; Cooke,
