On old bark of Beecli; rare. 'I"nl)ules in my specimens 1-2 

 mm. long, crowded and somewhat fasciculate; in its younger state 

 granuliform, soon annuliform, at length becoming cylindric and 

 enlarged u])ward ; externally silky with appressed hairs. 



2. S. OCHKACEA, Hoffm. Scattered, clavate-cylindric, tomen • 

 tose, ochraceous, white within. 



On rotten wood of Maple; rare. Tubules less than a mill- 

 meter in length, about .6 mm. in m\' specimens, and covered with 

 short rigid hairs ; they do not seem scattered to the naked eye, 

 but the lens shows that they are not crowded. The species is 

 closely related to S. anoma/a, Pers. but the tubules of the latter 

 rest upon a distinct floccose subiculum, while the mycelium of 

 the former is scarcely apparent.
