When 3'oung this Agaric closely resembles the preceding one from 

 which it is distinguished by its larger size, more scaly and less white 

 pileus, larger and more persistent annulus and larger spores. The 

 cuticle sometimes remains entire and sometimes cracks in a radiating 

 manner toward the margin, thereby giving to the pileus a sort of 

 fibrillose or virgate appearance. The annulus sometimes partly breaks 

 from its attachment to the stem and becomes almost movable. 



Agaeicus fe LINUS, Pers. 

 Cat Agaric. 



Pileus thin, subcampanulate or convex, suoumbonate, adorned with 

 numerous suMome?itose ovjloccose hlackish-hroion scales; lamellae close^ 

 free, white ; stem slender, rather long, equal or slightly tapering up- 

 ward, hollow, clothed with soft loose floccose filaments, brown, an- 

 nulus slight, evanescent; spores elliptical, -00025' — 0003' long, 

 •00016' — 0002, -broad. 



Plant 2' — 3-5' high; pileus '5' — 1-5' broad; stem 1' — 2" thick.

This is not a common species with us, having occurred thus far 

 only in the woods of our mountainous regions. The scales or adorn- 

 ments of the pileus are similar iu character to those of A. Fnesii, 

 but are much darker in color. Fries unites this Agaric with A. 

 clypeolarius as a variety, but says that it is so frequent and so con- 

 stant in the pine woods of Europe that it deserves to be noticed sepa- 

 rately. It is easily distinguished from .4. ruhrotinctns by the darker 

 color of the scales of the pileus, by the loose floccose filaments that 

 clothe the brown stem, by the fugacious annulus and the smaller 

 spores. 



Agaric us fuscosquajieus, Pk. 

 Brown-scaled Agaric. 



Pileus rather thin, hemispherical or convex, subumbonate, adorned 

 with numerous suhstrigose, erect or reflexed blackish-brown scales; 

 lamellse close, free, white ; stem short, rather stout, equal, hollow or 

 stuffed with a cottony pith, clothed with loose soft dingy floccose fila- 

 ments, bulbous, brown; annulus slight, evanescent; spores narrowly 

 elliptical, •00025'— -0003' long, -00012' — 00015" broad. 



Plant 2'— 3' high ; pileus 1-5'— 2-5' broad ; stem 3"— 4" thick. 



Pine and hemlock woods. Croghan. September. 



This species is closely related to the preceding one, and might, per- 

 haps, be considered a variety of it. It has the same color, but is dis-
