whitish, fibrillose, with a white mycelium at the base ; spores 

 elliptical, .00024 in. long, .OOolH broad, often containing a shining 

 nucleus, 



Pileus 2 to 3 lines broad ; stem 6 to 8 lines long. 



Damp naked soil in woods. Selkirk. July. 



This is a very small species closely allied to Ttiharia auto- 

 chthona, from which it is separated by the shape and color of the 

 pileus, the decidedly decurrent lamellae and the fibrillose stem. 

 As in that species, the spores are unusually pale. The drv pileus 

 is distantly sulcate or striate. 



Agaricus subrufescens ??. S2). 



Pileus rather thin and fragile, at first deeply hemispherical, 

 then convex or broadly expanded, often wavy or irregular, silky- 

 fibrillose or minutely and obscurely squamulose, varying in color 

 from whitish or grayish to dull reddish-brown, flesh white, 

 unchangeable ; lamella? close, free, at first white or yellowish- 

 white, then pinkish, finally blackish-brown ; stem minutely floc- 

 culose below the annulus, hollow, white, somewhat thickened or 

 bulbous at the base; the annulus membranous, white, externally 

 flocculose ; the mycelium white, forming slender branching root- 

 like strings; spores elliptical, brown, .00024 to .00028 in. long, 

 .00016 to .0002 broad. 



Pileus 2 to 4 in. broad; stem 2 to 6 in. long, 4 to 8 lines thick. 



Leaf mold. Glen Cove. October. W. Falconer. Also culti-

In the form of the young jMleus and in its color in the reddish 

 tinted specimens, also in the white color of the young lamellre, 

 this species makes an approach to A. cornpestriK var. rnfescens^ 

 but unlike that variety the wounded flesh does not become red. 

 From typical -4. crtm^>^s^W.s' it difl'ers in many respects — in the 

 thin flesh, the color of the young lamella?, the character of the 

 stem and its annulus and in its mycelium. It resembles more 

 c\o?,q\y A. 2>lacom/yces imd A. .nlvdticus, hnt from the former it 

 may be separated by the shape of the pileus and tiie more obscure 

 character of its scales and by its annulus, from the latter, by the 

 color of the pileus and the young lamella* and also by the annulus, 

 which is externally floccose-s»j nam ii lose and also not distant as in 

 that species.
