CLASSIFICATION OF AGARICS

 silkj shining above, apex mealy and striate, rarely with Loose Bhreds 

 forming a temporary ring. VEIL white, Qoccose-membranous, ;ii 

 firsl uniting the margin of the pileus with the Btem, very soon dis- 

 appearing. SPORES almost cylindrical-elliptical, 9-11 .\ I 5 micr., 

 smooth, red-brown under microscope. CYSTIDIA almost lance- 

 olate, * > i j sides and edge of gills, 10 to \ L0 L3 micr."

The description is adapted from Ricken's Blatterpilze. This 

 species has been much discussed, and is reported in mosl American 

 books. The pileus is brown when moisl according to most European 

 authors and occurs in the forests where it tonus caespitose tufts. 

 1 have not been able to distinguish it in the southern pari <>t' the 

 state, ''in have given u description from the mosl recenl work on 

 European Agarics, for tin- sake of comparison.

PILEUS 17 cm. broad, fragile, a1 first oval, then convex-campan- 

 ulate, hygrophanous, obtuse or subumbonate, umber-brown on disk, 

 gradually paler toward margin, whitish-tan or pale alutaceous when 

 dry, disk often retaining .-in umber shade and "/ length blackish 

 stained in spots, .it first dotted with white, flocculent, superficial 

 scales, soon denuded, even or obscurely wrinkled on margin, margin 

 hung by remains of veil in a dentiform manner. FLESH thin. 

 concolor. GILLS narrowly adnate, seceding, very narrow, crowd- 

 ed, ;it first dingy-white, soon pale Lilaceous-brown, then umber- 

 colored, edge minutely white-fimbriate. STEM 5-7 cm. long, rather 

 slender, 3-4 mm. thick-, tapering upward <>r subequal, hollow, 

 slightly toughish, white, dingj in age, often innately GLocculose scaly 

 then glabrescenl and shining, even, sometimes subcompressed. 

 SPORES elliptical, ti-Tx 1 micr., smooth, purplish-brown. CYSTI- 

 DIA none. STERILE CELLS on edge <»f gills, broadly cylindri- 

 cal, obtuse, abruptly short-stipitate, 36x10 micr. ODOR and 

 TASTE pleasant.

This differs from the solitary form <>t //. incertum, which also 

 occurs in woods, by the umber color of the entire very young pileus
