 One-third natural size. 



Micacei. Pileus with micaceous squamules, &>c. 



14. C. micaceus Fr. A. major. Pileus at first yellow-ferrug- 

 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 

 then fibroso-fibrillose, whitish. Gills 

 adnexed, lanceolate, linear in deli- 

 quescing, isabelline, becoming brown 

 at the edge. 



B. minor. Pileus yellowish - livid when 

 moist, ferruginous-ochraceous when dry, 

 date -brown at the disc, somewhat mem- 

 branaceous, but scissile, oval then campan- 

 ulate, 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 csespitose. The stems are often angular, 

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

 the middle, as in C. atramentarius. In abnormal forms the pileus is unequal, 

 ribbed-sulcate, transversely rimoso-squarrose. 



On stumps, the ground, &c. Common. April-Nov.
