156 Forty- FOURTH Report on the State Museum 



Thin woods. Eensselaer, Cattaraugus and Steuben counties and 

 Catskill mountains. August and September. 



This is a beautiful species, but it does not retain its colors well in 

 drying-. It is somewhat similar in appearance to the preceding 

 species, but it is easily distinguished from all the related ones by 

 its squamulose pileus and stem. As in the allied species, its 

 lamellae become discolored or spotted with age. It is perhaps 

 edible, but I have not yet had an opportunity to test it, and the 

 taste, though at first farinaceous and pleasant, is sometimes followed 

 by a bitterish unpleasant flavor. In wet weather the margin of the 

 pileus and upper part of the stem are sometimes studded with drops 

 of moisture of a reddish or orange color. 



Genuina 



Pileus neither moist nor viscid, generally floccose-squamose or 

 fibrillose, flesh soft, not hygrophanous, the margin at first involute 

 and subtomentose. 



The species of this tribe as well as those of the preceding one may 

 be arranged in two groups depending on the character of the 

 lamellae. In one the color of the lamellae is unchangeable in the 

 other it changes with age. Some of the species have a slight fari- 

 naceous odor, at least when broken, others are inodorous. In most 

 of them the pileus is adorned with squamules or fibrils.
