LACTARIAE OF THE UNITED STATES 107 
found in the Catskills a small form of what I take to be Г. albidus 
Pk. The species belongs to the section Russularia, and I am not 
quite sure it is more than a white variety of 2. varius Pk., which 
belongs to the Russuaria.” Further collections will undoubtedly 
serve to place this either as a distinct species or as a form of Lac- 
taria varia. : 
DOUBTFUL SPECIES 
Lactaria mitissima has been reported from Pennsylvania by 
Herbst and from California by Harkness & Moore, but the spec- 
imens from which the determinations were made have not been 
preserved. The description given by Herbst seems to conform 
very closely to Г. subdulcis. The species is described in Mc- 
Ilvaine's One Thousand American Fungi, 181, and is figured in 
Cooke's British Fungi, 2/. гоог. It may be distinguished from Z. 
subdulcis by the more golden-fulvous color of the pileus and the 
orange stem, and by the more abundant latex. In Fries, Monogr. 
Hym. Suec. 2 : 180, the pileus is described as subviscid when moist. 
If this condition exists, the species should be classed with the 
Quietae. -
