not soaked, the center at times a little darker, the thin margin soon 

 withering to nearly black. Flesh very thin, about 0.6 mm. thick 

 near stem, taste woody and a little bitter, odorless, concolorous. 



Gills crowded, color of unsoaked cap, in places becoming distinctly 

 lilac in drying, sinuate, about 2-3 mm. wide. 



Stem concolorous, 2.3-3 cm. long, 1.3-3.5 mm. thick, nearly 

 equal, base with white mycelium; mostly glabrous, a large hollow, 

 toughish (cap rather tender). 



Spores (of No. 4543) white, smooth, subspherical, 3.5-4 x 3.7- 

 5.5 [I, no cystidia. Basidia long-clavate, about 6 \x, thick, 4-spored 

 Hymenium about 29-33 [jl, thick. Threads of the gill trama parallel, 

 narrow toward the margin, more swollen toward the cap. 



I am considering this a form of C. exsculpta, but the color is buff, 

 not yellow or reddish-yellow and the gills are not bright suphur yellow, 

 Also it does not grow on decaying wood but on the ground.

This is certainly C. cirrata, agreeing in all respects with Persoon 's
