The Saprophytic Fungi of Eastern Iowa. 37 



Siihgenus Lepiota. 



Veil universal and concrete (blended) with the cuticle of the 

 pileus. Hymenophorum distinct from the stem. — Berk. 



The veil is blended with the cuticle of the pileus, but put 

 under tension by the expanding pileus breaks up and usually 

 gives the whole surface a scurfy appearance. 



5. Agaricus procerus. — Scop. 



Pileus at first ovate then expanded, umbonate, the margin 

 incurved, rather flesh}- but becoming somewhat tough and 

 leathery when dry, white, spotted with more or less con- 

 spicuous pale brown patches or scales; lamellae pale flesh 

 colored, remote from the stipe which is tall slender bul- 

 bous, somewhat scaly and furnished with a movable ring. 



Height 8'-i6'. Pileus 5'-6'. August and September. 



This is by all odds our finest mushroom. Common in 

 woods and orchards, it towers above all others and is conspic- 

 uous from far. Specimens frequently reach sixteen inches, 

 and I have seen them taller. Said to be edible. 



6. Agaricus acutesquamosus. — Weinvi. 



Pileus convex, sub-umbonate, covered with small erect acute 

 scales; lamellae narrow and free: stipe bulbous with a fixed 

 broad annulus. 



Height 3'-4'. Pileus 2'-3'. August and September. 



Not common. The specimens referred to this species are 

 found in rich woodland, are pale brown in color with some- 

 thing of a reddish cast and retain color in drying. 



7. Agaricus americanus.— P/-. 



Pileus convex, umbonate, squamose with distinct rather nar- 

 row retreating scales; lamellae free; stipe hollow, smooth, bul- 

 bous, the bulb greatly elongated, annulate with fixed ring. 



Height 3'-4'. Pileus 2 '-3' August. 



Common along the fine of the C. R. I. & P. railway. The 

 plant may have been so introduced. Dr. Peck mentions
