tinge more pronounced toward center; margin strongly decurved,

to nearly black when bruised, 1-1.5 cm. thick near center; stem 
short, stout, solid, terete, or compressed, somewhat swollen toward 
base, inclined, excentric to lateral, concolorous with pileus becom- 
ing darker toward base, scabrous dotted with abortive teeth ; teeth 
short, stout, terete, subacute, irregular in length, uniformly short 
to lacking toward margin, decurrent becoming abortive, pale- 
gray to whitish turning dark when bruised, 1-5 mm. long, 1 and 
2 to one millimeter ; spores brown, tuberculate, uniguttulate, sub- 
globose to ovoid, 7-7.5 x 7.5-9 м; taste mild, agreeable.

The type specimen is larger than those described above, being 
10-12 cm. wide. It is but just to say that Dr. Peck does not 
think the above described plants represent his species, but except 
in size I cannot distinguish any essential difference. It is wholly 
unlike anything I have seen and is evidently a good but rare 
species. As the plant is large and conspicuous in appearance it 
seems remarkable that it has not been more often found.
