40 JOUENAL OF THE MlTCIIELL SoCIETY \_June 



a Lactarius. Cap up to about 8.5 cm. broad, depressed in center, the 

 margin bent down; surface smooth, dull, dry, and a uniform light 

 buff. Flesh thin and transparent, white, the grub channels a creamy- 

 yellow. Milk white, mild, not changing, not very abundant. 



Stem only 3.3 cm. long, 1.3 cm. broad at top, tapering downward, 

 very fragile, stuffed, hollowed by grubs. 



Gills color of cap, 5 mm. deep, wavy, many short and few branched, 

 reaching the stem but not decurrent. 



Spores a warm buff color (Ridgway), spherical, tuberculate and 

 ridged, 5.5-9.2iU in diameter. 



The principal difference between our plant and L. quietus is in the 

 lighter color of the former. This, however, may not be of much con- 

 sequence. The dried plant is like specimens of L. quietus from Miss 

 Burlingham, except that the spores average a little smaller in ours. 



This plant seems to agree well with L. pallidus, but as there is 

 doubt about the species being American and as I have no authentic 

 specimens for comparison, the determination must be uncertain until 

 further evidence.

L. paludinellus Peck, 



This has so far been found in this State only in our mountains. 

 The following description is by Miss Burlingham (Mem. Torr. B. C. 

 14:66. 1908, as L. paludinellus) : 



"Pileus fleshy, thin, convex, then plane-umbilicate to depressed in 

 the center, sometimes with a small umbo, brownish-drab (302 t. 2) 

 to dark-fawn (307), expallent, slightly viscid when wet, glabrous, 

 12 mm. to 4 cm. broad, margin at length slightly striate ; gills white 

 to cream colored, becoming darker with age, pruinose, many forking 

 near the stem, close, adnate or slightly decurrent, thin, up to 4 mm. 

 broad; stem of the same color as the pileus or paler, nearly equal, 

 glabrous, except at the base, which is slightly villose when growing in 

 moss, stuffed, sometimes hollow, 2-3 cm. long, 3-4 mm. thick; flesh
