brous and the stem is practically glabrous from the first. Although 
the type specimens of 2. regalis do not show any very young plants, 
some of them seem to be young enough to have retained the to- 
mentum on the margin. Since, however, only the type collection 
is known, I prefer to leave the species in doubt until further col- 
lections can be made. 
LACTARIA SANGUINALIS(Batsch) Schrót. [Lactarius controversus Fr. | 
This species has been reported from California by Harkness & 
Moore, but the specimens from which the determination was made 
were not preserved. The species is described in МсПуате’$ One 
Thousand Am. Fungi, 164. 1902, and is well figured by Batsch, 
Elench. Fung. ai, 36. f. 201; by Fries, Sverig. Svamp. 2/. 20; by 
Cooke, Br. Fungi, //. тооз; and by Gillet, Champ. Fr. ai 160

but was ommitted from his list of Zactariae in the 38th Report, 
1885. 
IV. CROCEAE 
Pileus very viscid when young or in wet weather, the margin

of yellow, zonate, plants large, flesh rather compact ; gills darker 
with age, and more or less pruinose; latex acrid, white, changing 
to yellow.

15. L. crocea 
15. Lactaria crocea sp. nov. 
Pileus fleshy, brittle, broadly convex-umbilicate with the mar-

deflexed, saffron-yellow to orange-cadmium (49), subzonate, expal- 
lent, very viscid when moist, glabrous, 5-10 cm. broad, margin in- 
volute and pruinose-downy at first, then glabrous; gills pallid, then 
honey-yellow (35), and at length yellowish-buff ( 310. г. г), be- 
coming cadmium (47. 2. 7) where cut or bruised, seldom forking, 
not close, adnate, 5-6 mm. broad; stem of the same color as the
