GE}<US CORTINA RIUS 



This genus contains many species which are distinguished 

 by the rusty yellow colour of their spores and by the webby 

 character of the veil. It is of the utmost importance in identify- 

 ing species of Cortinarius to know the colour of the gills of the 

 young plant, as the gills of the old plants are almost uniform in 

 colour, owing to their being dusted with the rusty yellow spores. 

 In addition, one should carefully note the colour of the young 

 plant compared with the old ; the surface, whether sticky or dry, 

 smooth or hairy; the taste; and the markings left on the stem by 

 the retreating veil. All species have their gills attached to the 

 stem, and some have them notched at the stem end. They may 

 be looked for along the borders of woods and groves in hilly 

 regions, during the latter part of the summer.
