 inous, the even disc darker, at length date - brown - fuscous, 



somewhat membranaceous, undu- 

 lato-lobed, rimosely split, striate, 

 but not opening into furrows, at 

 first covered with micaceous scales, 

 smooth when these separate. Stems 

 7.5 cent. (3 in.) to as much as 20 

 cent. (8 in.) long, hollow and soft, 

 even, at first obsoletely white-silky

 date -brown at the disc, somewhat mem- 

 branaceous, but scissile, oval then campan- 

 \i\a.te, forked-sulcate, the furrows micaceous, 

 soon split at the margin, but even at the 



disc. Stem equal, 4 mm. (2 lin.) thick, even, sometimes curved, becoming 

 smooth, white. Gills white then livid, at first at the edge then wholly fuscous- 

 blackish. 



Very changeable, for the most part caespitose. The stems are often angular, 

 from mutual pressure, and sometimes when young have the thickened knot at 

 the middle, as in C. atrame/itarius. In abnormal forms the pileus is unequal, 

 ribbed-sulcate, transversely rimoso-squarrose.
