 Cooke, III.. PI. 259. 



PILEUS L-5 cm. broad, elongated in n iredgt shaped to tpathu 

 hih manner, 2-10 cm. long, tapering to ii stem-like iu-<-. ///.//<;• 

 excepl sometimes tomentose toward base, irhitish i<> broicn, tan or 

 r< ddish brown . margin al first in rolled and finely Htrinte when 

 moist. FLESH rather thin, white, Homogeneous. (JILLS decur 

 rent, very narrow, crowded, whitish or yellowish, '»/'/< fimbriate. 

 STEM nol apparenl from above, on the underside ii is somewhal 

 distinguishable as a compressed, Bhort, Bomewhal villose portion 

 "ii which the .uills descend. SPORES globose, minute, ■'• I micr. in 

 diameter, whin- in mass. CYSTIDIA abundant. 



Caespitose on decaying wood, Logs, stumps, from underground 

 portions of wood, etc. July i<> September. Marquette. Infrequent. 



Close to /'. spathulatus, which Inis oval-elliptical spores. The 

 European authors as a rule give the Bpores under the description 

 of ihis species as oval-elliptical, bo thai if Peck's conception is 

 correcl their measurements were taken from a form like Peck's P. 

 spat h iilul us. Fries and apparently mosl others have considered /'. 

 s/niiii iiioi us as a variety with ;i mure broadly expanded and 1 • » I >< -• I 

 pileus. Our species is distinguished from /'. porr'ujens and /'. albo 

 hiiiius by the presence <>i cystidia, as well as bj the non i-«-^.ii |>i i ■ 

 pileus in the young stage.
