 or many spines. Spores bright yellow or orange in mass, minutely 

 warted, 11-13 /x diam.

This species appears to be confined principally to the moun- 

 tains of eastern North America. It was rather common in the 

 Laurentian mountains of Quebec in 1938, and in the Great Smoky 

 Mountains of North Carolina and Tennessee in 1939. The mot- 

 tled appearance of the sporangia, and the spinose elaters with 

 short ends, distinguish it from other species of Trichia.

Plasmodium chocolate-brown (Macbr. & Martin). Sporangia

 black, erect, stout, furrowed, separated from the cavity of the

 consisting of bright yellow elaters 4-6 m wide, marked with three 

 or four prominent spiral bands, smooth and ending in short, 

 slender, often curved tips. Spores yellow, minutely spinulose, 

 11-13 /x diam.

Closely allied to T. Botrytis, this is distinguished by the 

 elaters having short, tapering ends. It is usually found in the 

 same places and at the same time with T. erecta, about the end of 

 August.
