Trichia Jackii, Rost. 



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

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

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

 cylindrical, 5 — 7 ju, 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 hands, slightly curved or sinuous, 

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

 pits, 12 — 15 /x diameter.

Allied to Trichia ahrupta, 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 /x 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 hands 

 ivith mimcte depressions usually arranged in a single row, 9 — 11 /ut 

 diameter.
