Nolanea Babingtoniit (Blox.) Sacc. Syll. Fung. 5: 717. 1887. (Agaricus Babingtonii 
Blox.; Berk. & Br. Ann. Mag. Nat. Hist. II. 13: 399. 1854.) Reported from the eastern 
United States and Cuba, but the specimens I have seen are incorrectly determined. 
Nolanea pascua (Pers.) Quél. Champ. Jura Vosg. 89. 1872. (Agaricus pascuus Pers. 
Comm. Fung. Bavar. 94. 1800.) Reported from various localities in the United States but 
I find no American material that corresponds to European material so named or to authentic 
descriptions and figures.

Berk. & Curt. Ann. Mag. Nat. Hist. III. 4: 290. 1859.) Described from specimens col- 
lected by Sprague in New England among wet moss in a pine swamp. ‘Types have not been 
examined. The following description indicates a very distinct plant related to Entoloma

spores quadrangular or irregular, 14 »; stipe golden-yellow, hollow, 8 cm. long.
