yellowish; stem compressed, sometimes channeled above, grayish- 

 tomentose; spores elliptical, .0003 in. long, .00016 to .0002 broad; 

 odor and taste farinaceous. 



Ground. Sandlake. June. Edible. . 



It grows singly or in tufts and is an inch or more in height. The 

 margin is thin and sometimes striatulate and reflexed. Toward the 

 base the flesh is thicker than the breadth of the lamellse. The cuticle 

 is tough and separable. The flesh is said by Gillet to be tender and- 

 delicate. Persoon describes the disk as spongy-squamulose, but in our 

 specimens it is merely pubescent or tomentose. 



The species was united as a variety to P. petaloides by Fries, and is 

 described by Gillet nnder that name, but it seems to me to be suffi- 

 ciently distinct in its habit, habitat, color and spores to be regarded 

 as a species. 



Pleurotus petaloides, Fr. 



■Petal-like Agaric. Petaloid Pleurotus. 



Agaricus petaloides, Bull. 



Pileus rather thin, eight to twenty lines broad, cuneate or spatlm- 

 late, tapering behind into the short compressed generally villose- 

 tomentose stem, convex or nearly plane, glabrous or with a minute 

 grayish pubescence or tomentum toward the base, sometimes striatulate 

 on the margin when moist, whitish pale-alutaceous or brownish; 

 lamellae crowded, linear, decurrent, whitish or yellowish; spores 

 minute, globose, .00013 to .00016 in. broad. 



Decaying wood. Buffalo. G. W. Clinton. East Worcester, Karner, 

 Catskill and Adirondack mountains. July and August. 



This is closely allied to the preceding species, with which it is united 

 by most writers, but the striking difference in the size and shape of 

 the spores indicates that they should be kept as distinct species. 

 With us the petal-like Agaric is much more frequent in its occurrence 

 than the spathulate Agaric. 



In shape and general appearance it closely resembles Crepidotus 

 applanatus, from which it may be distinguished by its paler lamellae, 

 smaller white spores and more colored pileus. 



Pileus at first resupinate, tlien reflexed, sessile; lamellce radiating 

 from an eccentric point. 



Pleurotus porrigens, Fr. 

 Prolonged Agaric. Pine Pleurotus. 

 Agaricus porrigens, Pers. 

 Pilens rather thin, at first resupinate and suborbicular, then reflexed 

 and prolonged, obovate subelliptical or ear-shaped, often longer than 

 broad, one to three inches long, sessile, glabrous or villose-tomentose 

 toward the base, pure lohite, the margin involute when young, some- 

 times lobed in large specimens; V^meW-dQ narroio, linear, thin, croivded, 

 sometimes slightly forked or anastomosing at the base, white; spores 

 subglobose, .00025 to .0003 in. broad. 



Much decayed wood of pine and hemlock. Buflalo. G. W. Clin- 

 ton. Karner, Catskill and Adirondack mountains. Autumn. 



The prolonged Agaric is a fine species, easily known by its pure
