Stem ventricose, whole surface covered with scales formed by the 
laceration of the cortex, hollow within, composed of shining, 
parallel, silky fibres, with a central medulla in the median cavity ; 
peridium somewhat plane, elevated in the middle, coriaceous, thin, 
scarcely spongy, white below and even, cellular above, brownish-

Wholly white, at length ferruginous from the scattered spores ; 
peridium campannlate-mitrate. seated on a solid, very long stum, 
which is slightly thickened above, clad with paleaceous scales ;

upwards, woody, hollow within, pallid fibres from the pileus decur- 
rent through the whole cavity, stem in the upper part torn into 
large membranaceous scales, in the lower part invested with linear-

Exoperidium continuous, eventually irregularly ruptured ; endo- 
peridium furnished with an apical toothed ostiolum, spore sac when 
young filling the endoperidiuin, afterwards contracting towards the 
apex, and remaining attached to the teeth of the ostiolum ; stem

Exoperidium breaking up early into small blackish granules, 
which remain attached to the ocbraceous, subglobose endoperidium 
(1 c.m. diam.) ; ostiolum black internally, as well as the margin of
