On decaying Agarics. [Low. Carolina.] 



Flocci septate, filled internally with distinct granules, thinly scattered, 

 divergent, springing from the branched mycelium in such a manner that 

 several of the sterile flocci unite to give off the simple sporidiferous thread j 

 sporidia exactly fusiform. — M. J. B.

Byssoid ; fertile flocci simple, penetrating the globose spo-

Fertile flocci about 5 in, high, four times as thick as in M. clavatu?, filled 

 with distinct granules; sporangia depresso-globose, sometimes collapsing 

 slightly and nodding ; sporidia rather large, containing globose sporidiola, 

 which easily separate; mycelium thick, expanded, pure n'hite, closely inter- 

 woven. — M. J. B.
