ochraceous-brown on disk, lighter toward the margin which becomes 
cenulate and upturned in older specimens, slightly pruinose at first,

cowded, rather narrow, interspaced with anastomosing veins, much 
crisped, at first nearly white, then becoming ferruginous from the 
spores: stem 7-10 long, o.1-0.3™ thick, tapering from the somewhat 
bulbous base, yellowish-white, pruinose at base, hollow, fragile: spores

___ The specific name is based on the peculiar character of the gills 
Which are always crisped as soon as the pileus isexpanded. Professor 
Charles H. Peck, to whom specimens of the above fungi were referred,

_ ‘ter have been collected in the same localities during the past three 
“asons seems sufficient proof of the constancy of this character, and 
_ ““asequently, would indicate that this form is worthy of specific rank.
