DovuBTFUL SPECIES 
Camarophyllus caprinus (Scop.) P. Karst. Bidr. Finl. Nat. Folk 32: 224. 1879. (Agaricus 
caprinus Scop. Fl. Carn. ed. 2. 2:438. 1772. Hygrophorus caprinus Fries, Epicr. Myc. 326. 
1838.) Reported from the eastern United States by certain mycclogists, but possibly confused 
with dark forms of H. hypothejus. 
Hygrophorus metapodius Fries, Epicr. Myc. 328. 1838. (Agaricus metapodius Fries, 
Obs. Myc. 2: 110. 1818.) Described from Sweden and reported from the eastern United 
States by certain mycologists. Peck remarks that the American specimens are not all viscid 
nor does the context turn red when wounded as in typical specimens. I have seen no material 
that corresponds with authentic material from Europe. 
Hygrophorus nitratus (Pers.) Fries, Hymen. Eur. 421. 1874. (Agaricus nitratus Pers. 
Syn. Fung. 356. 1801.) Reported from the United States by some mycologists but possibly 
confused with C. auratocephalus. 
Hygrophorus Ravenelit Berk. & Curt. Ann. Mag. Nat. Hist. II. 12: 424. 1853. De- 
scribed from specimens collected in wet ground in South Carolina by Ravenel. The pileus is 
convex, cespitose, 4-6 cm. broad, orange-colored; lamellae emarginate, paler; stipe yellow, 
10-12 cm. long. The stipe is usually long and thick, and whitish at the base, as in Cama- 
rophyllus auratocephalus. A sketch of the single type specimen at Kew and a mount of the 
spores, which are oblong-ellipsoid, smooth, hyaline, 7-8 X 5 y, were prepared for me by Miss 
Wakefield. 
Hygrophorus? variolosus Fries, Nova Acta Soc. Sci. Upsal. III. 1: 29. 1851. Described 
from specimens collected in Costa Rica by Oersted, who made colored drawings of fresh speci- 
mens and also preserved some in alcohol. ‘These specimens could not be found in Europe, but 
the drawings strongly suggest Armillaria alphitophylla. 
39. HYGROPHORUS Fries, Gen. Hymen. 8. 1836. 
Hygrophorus § Limacium Fries, Epicr. Myc. 320. 1838.

lamellae waxy, adnate or decurrent: spores hyaline: stipe central, fleshy, usually solid: veil 
glutinous, forming an inconspicuous annulus or squamules on the stipe. 
Type species, Agaricus chrysodon Batsch.
