GENERA AND SPECIES OF MUSHROOMS 



than the cap except the bulb which is the color of the cap and 

 sticky (viscid) 3 to 5 inches long. 



Spores rusty (ochraceous) ; broadly elliptic; rough; .00045 

 to .00055 by .0003 to .0004 inch in diameter. 



The corrugated cortinarius is a well-marked and easily rec- 

 ognized species. Though the color of the pileus (cap) is 

 variable, its viscid, corrugated surface and the viscid bulb of 

 the stem afford easily recognized characters. Sometimes the 

 wTinkles join with each other in such a way as to give a net- 

 like appearance. The margin in young plants is incurved. 

 The bulb in the young plant is even broader than the cap, 

 which then appears to rest upon it. The plants sometimes 

 grow in considerable numbers and as an edible species it is 

 not to be despised. Peck. 



Cortinarius violaceous; violet cortinarius. Plate IX, 

 Species 44. 



On ground among fallen leaves in the woods; July and 

 August ; edible ; scattered or solitary. 



Cap convex, later becoming nearly plane; dark violet, 

 adorned with numerous hairy tufts or scales; flesh, tinged with 

 violet; 2 to 4 inches broad. 



Gills when young, colored like the cap, but becoming rusty 

 when old; attached to the stem and notched at the stem end. 



Stem colored hke the cap; bulbous at the base; solid; minute 

 fibres on the surface; 3 to 5 inches long. 



Spores rusty; nearly elliptic; .0005 inch long. 



The genus Crepidotus 



Mushrooms of the genus Crepidotus are very variable in 

 the shape of their caps but are commonly either wedge- 

 shaped or spatulate. The caps quickly curl up on drjang 

 unless they ar: placed under pressure. They grow in groups 

 and the caps are often stained by the rusty spores. Peck.
