(409 ) 
Putrescent: cells of the sporocarp vesicular, lactiferous: 
pileus fleshy, convex or depressed, dry, glabrous, epelliculose : 
lamellae adnate or decurrent, color unchanging: spores 
white or whitish, usually globose, echinulate: veil none: 
stipe central, fleshy 
Type, Lactarius piperatus Fries. 
The genus is taken to equal Lactarius, Tribe 1, § 3, 
Prperatz, of the Sylloge. 
11. GLOEOCYBE gen. nov. 
Putrescent: cells of sporocarp vesicular, lactiferous: 
pileus fleshy, depressed or infundibuliform, slimy-viscid, 
margin expanded: lamellae adnate or decurrent, unchang- 
ing: spores white or whitish, globose, echinulate: veil none: 
stipe central, fleshy. 
Type, Lactarius insulsus Fries, Epicr. 336. 1838. (Syll. 
5: 427.) 
This equals Lactardus, Tribe 1, § 2, Lemacent, of the 
Sylloge. 
12. GALORRHEUS Fries, Syst. Orb. Veg. 75. 1825. 
Putrescent: cells of sporocarp vesicular, lactiferous: 
pileus fleshy, depressed or infundibuliform, moist or viscid, 
tomentose, the margin at first strongly involute: lamellae 
adnate or decurrent, unchanging: spores white or whitish, 
globose, echinulate: veil none: stipe central, stout, fleshy. 
Type, Lactarius controversus Fries. (Syll. 5: 426.) 
As here defined this equals Lactarius, Tribe 1, § 1, Tre 
cholomoidet, of the Sylloge. The name Galorrheus was 
first used by Fries as a subgenus in 1818 (Obs. Myc. 2: 
188). Why he abandoned it in his later works for Lactarius 
is not apparent. 
13. LACTARELIS gen. nov. 
Putrescent: cells of the sporocarp vesicular, non-lactif- 
erous: pileus fleshy, thick, moist or subviscid, pellicle non- 
separable or none, umbilicate or infundibuliform, margin at 
first involute: lamellae adnate-decurrent, heterophyllous:
