Trichia Jackii, Rost. 



Sporangia usually crowded, sessile on a narrow or broad base, 

 hypothallus well-developed, circular, angular, or elliptical in 

 shape, dull yellow; mass of elaters and spores yellow; elaters 

 cylindrical, 5 7 n thick, tips smooth, acute, straight or a little 

 bent, spirals not very prominent, distant, sometimes with 

 rudimentary spinules; spores globose, with scattered, slightly 

 elevated, irregular, broad fiat bands, slightly curved or sinuous, 

 not combined to form a network, surface of bands with minute 

 pits, 12 15 /x diameter.

Allied to Trichia abrupta, but distinguished by the fewer 

 and longer bands on the epispore, and the undivided tips of 

 the elaters. 



Trichia intermedia, Mass. (figs. 180 182). 



Sporangia subglobose, sessile on a broad base, crowded, often 

 irregular from mutual pressure, smooth, shining, bright ochre ; 

 mass of spores and capillitium clear pale chrome-yellow ; threads 

 simple, cylindrical, 8 10 p thick, ending rather abruptly in a 

 short, smooth apiculus, spirals rather close, not prominent, 

 sometimes branched, with a few rudimentary scattered spinules, 

 and connected by thinner raised bands running more or less 

 parallel to the long axis of the elater; spores globose, with a 

 few distant raised flat flexuous bands that anastomose to form 

 an irregular network, often leaving free ends, surface of bands 

 with minute depressions usually arranged in a single row, 9 11 p 

 diameter.
