96 NORTH AMERICAN FLORA {VoLuME 10 
Fung. 343. 1801.) Reported from many parts of the United States by the older mycologists, 
but no correctly determined American material has been found either at Albany or elsewhere.

Myce. 1: 208. 1821.) Reported from New York by Peck and from Maine by Miss White, 
but nong of these specimens corresponds with authentic European material. 
Leptonia incana (Fries) Gill, Champ. Fr. 414. 1876. (Agaricus incanus Fries, Syst. 
Myc. 1: 209. 1821. Not A. incanus Pers. 1801.) Reported from New York by Under- 
wood and Atkinson and from Ohio by Hard. Authentic specimens from Bresadola appear to 
be quite different from American material.

scabrosus Fries, Epicr. Myc. 154. 1838.) Reported by Peck as growing in swamps in New
