; Flammula inopoda (Fries) P. Karst. Bidr, Finl. Nat. Folk 32: 407. 1879. (Agaricus 
tnopus Fries, Obs. Myc. 2: 32. 1818.) Reported from North Carolina, but I find nothing 
in America to correspond to specimens from Bresadola. 
Flammula lubrica (Pers.) Quél. Champ. Jura Vosg. 232, 1872. (Agaricus lubricus Pers. 
Syn. Fung. 307. 1801. Not A. lubricus Scop. 1772.) Reported from New York by Peck, 
but his specimens do not appear to have been correctly determined. 
; Flammula mixta (Fries) P. Karst. Bidr. Finl. Nat. Folk 32: 403. 1879. (Agaricus 
mixtus Fries, Epicr. Myc. 185. 1838.) Reported by Kauffman from the Adirondacks. 
T have not seen his specimens, but find nothing at Albany to match specimens from Bresadola. 
Flammula peregrina (Fries) Sacc. Syll. Fung. 5: 814. 1887. (Agaricus peregrinus Fries, 
Elench. Fung. 1: 31. 1828.) Collected by Benzon on trunks in Santa Cruz, West Indies. 
Types not found. 
Flammula picrea (Pers.) Gill. Champ. Fr. 533. 1876. (Agaricus picreus Pers. Ic. Descr. 
Fung. 14. 1798.) Reported from Greenland and from North Carolina. I have seen no 
American material that corresponds with specimens from Romell. 
Flammula ricensis (Fries) Sacc. Syll. Fung. 5: 814. 1887. (Agaricus ricensis Fries, 
Nova Acta Soc. Sci. Upsal. ITI. 1: 24. 1851.) Collected by Oersted on the ground in Costa 
Rica. It was not figured, but a number of specimens were preserved, none of which could 
be found either at Upsala or Copenhagen. It differs from most tropical species of the genus 
in being terrestrial. 
Flammula sapinea (Fries) Quél. Champ. Jura Vosg. 98. 1872. (Agaricus sapineus Fries, 
Syst. Myc. 1: 239. 1821.) Reported from most of North America, but confused with G. 
penetrans, which seems to account for all the American material examined. 
Gymnopilus viridans Murrill, Mycologia 4: 257. 1912. (Flammula viridans Murrill, 
Mycologia 4: 262. 1912.) Described from specimens collected near Seattle, Washington.
