tapering upward, often curved, minutely toinentose, containing a 

 whitish pith ; spores^subglobose, minute, .00015' in diameter ; flesh 

 abounding in a thin watery or serum-like juice, changing to pur-

This is a very remarkable and somewhat aberrant species. In 

 color it resembles dark forms of Hychium gelatinosum. In texture 

 it is more firm and fleshy than that plant. The stem is sometimes

 narrow, crowded, rounded at the stem and slightly emarginate, 

 brownish-lilac; stem equal, smooth, stuffed, reddish-brown ; spores 

 subelliptical, minute, .00012' long.

Kotten logs and fallen branches in woods. Portville. Sep-
