yellow, or ferruginous, often becoming brown with age; lamellae 

 adnate or decurrent, subdistant, thin, arcuate, pale yellow; spores 

 6-y by 3-4 fi; stipe tough, elastic, hollow, blackish brown, covered 

 with tawny tomentum which forms minute, meallike patches at the 

 apex and a more or less dense mat at the base, 2-6 cm long, 1-1.5 

 mm thick. 



Upon vegetable mold, often among grass and moss. Not un- 

 common. 



This species has a wide distribution in America as well as in 

 Europe. It seems to have been known in America as M. v e 1 u - 

 t i p e s (Clements, Crypt Form. Colo. 182) and asM. flammans 

 Cooke (not Berk. 1856) (Rav. Fungi Am. 467). In Europe it seems 

 to be known asM. cauticinalis (Sw.) Fr. or M . cauli- 

 cinalis. (Not M. Agaricus cauticinalis Bull.) 

 Specimens from Romell in Sweden under the name M . cauti- 

 cinalis fulvo-bulbilosus seem to be identical with our 

 New York form. Fries says of M. cauticinalis (Epicr. 

 Myc. 1838) that it is very similar to Omphalia campanella. 

 Peck (N. Y. State Mus. Bui. 67) says, " Similar in color to 

 Omphalia campanella, but differing in its more scattered 

 mode of growth, its longer stem sprinkled with tawny mealy par- 

 ticles, and in its less distinctly umbilicate pileus."
