Omphalia chlorocyana (Pat.) Sacc. Syll. Fung. 5: 336. 1887. (Agaricus (Omphalia) 
chlorocyanus Pat. Tab. Fung. 1: 145. 1885.) Specimens collected by Earle in Alabama, which 
are unfortunately without field notes, appear to be related to this species. 
Omphalia grisea (Batsch) Quél. Ench. Fung. 45. 1886. (Agaricus griseus Batsch, Elench. 
Fung. Contin. 1: 87. 1786.) Reported from Maryland and Alabama. Not seen at Albany. 
This species greatly resembles Prunulus and the lamellae are only slightly decurrent. 
Omphalia hepatica P. Karst. Bidr. Finl. Fungi 32: 133. 1879. ‘This species appears to 
be credited to Batsch and Fries and may be nothing more than Agaricus subhepaticus Batsch. 
(See Batsch’s figure 211.) It is reported from Massachusetts, Connecticut, and Rhode Island, 
but is not to be found at Albany. 
Omphalia rhyssospora (Mont.) Sacc. Syll. Fung. 5: 333. 1887. (Agaricus (Omphalia) 
rhyssosporus Mont. Syll. Crypt. 113. 1856.) Described from specimens collected on fallen 
leaves in woods near Columbus, Ohio. ‘The types at Paris are poor, but show that the species 
is not an Omphalia. From the specific name, one would judge that the spores were rose- 
colored and the species is probably an Entoloma. 
Omphalia subgrisea Peck, Ann. Rep. N. VY. State Mus. 41: 63. 1888. Described from 
specimens collected on decayed wood of yellow birch at Blue Mountain Lake in the Adiron- 
dacks. The types are not to be found at Albany, the only specimens there being from Port 
Jefferson and these are questioned as to determination. Peck has remarked that this species 
is probably an Ecczlia. 
33. GALACTOPUS Earle, Bull. N. Y. Bot. Gard. 5: 426. 1909. 
Pileus convex, the margin usually at first appressed: lamellae adnate or adnexed, bleeding 
when cut: spores hyaline: stipe central, tubular, bleeding when cut.

1. Galactopus rugosodiscus (Peck) Murrill. 
Agaricus (Omphalia) rugosodiscus Peck, Bull. Buffalo Soc. Nat. Sci. 1: 48. 1873. 
Mycena rugosodisca Sacc. Syll. Fung. 5: 293. 1887. 
Omphalia rugosodisca Peck, Ann. Rep. N. Y. State Mus. 45: 34. 1893. 
Pileus thin, broadly convex or nearly plane, umbilicate-obtuse or slightly wmbonate, 
sometimes slightly umbilicate, 12-24 mm. broad; surface glabrous, hygrophanous, rugose on 
the disk, brown and striatulate when moist, paler when dry, margin thin, often wavy: lamellae 
natrow, crowded, arcuate or plane, adnate, white, emitting drops of a watery juice where cut 
or broken: spores ellipsoid, 6-7 X 4 u: stipe short, glabrous, whitish or colored like the pileus, 
hollow, often curved, 2.5 cm. long, 1-2 mm. thick. 
TYPE LOCALITY: Worcester, New York. 
Hasrtat: On decaying prostrate trunks of coniferous trees, especially hemlock. 
DISTRIBUTION: Maine and New York. 
2. Galactopus succosus (Peck) Murrill. 
Agaricus (Collybia) succosus Peck, Bull. Buffalo Soc. Nat. Sci. 1: 46. 1873. 
Mycena succosa Sacc. Syll. Fung. 5: 293. 1887. 
Pileus rather firm, campanulate or convex, cespitose, 2-4 em. broad ; surface minutely 
tomentose, cinereous or very pale reddish-gray, darker at the center, the margin exceeding the 
lamellae: context abounding in a thin watery or sertum-like juice, changing to purplish and 
black when cut; lamellae slightly ascending, thin, crowded, emarginate with a slight decurrent 
tooth, tapering toward the outer extremity, whitish with a pale-reddish-gray tint: spores sub- 
globose, minute, 4-5 yu: stipe firm, equal or slightly tapering upward, often curved, minutely 
tomentose, containing a whitish pith, pale-reddish-gray at the apex, dark-reddish-gray below, 
4-8 cm. long, 2~3 mm. thick.
