Плозт.: Crossland, New and Crit. Brit. Fungi, Naturalist |

DISTINGUISHING FIELD-MARKS : The gills are very narrow and | 
so crowded when young that а space between them is scarcely - 
visible, and while tinted dull-yellowish when young, they become | 
white with age. Тһе abundant white latex dries glaucous-green, | 
which characteristic separates the species from all the other mem- | 
bers of this group. It differs from L. pergamena also by the thick | | 
flesh of the pileus, and from Г. piperata іп its narrower and more | 
crowded gills. It was abundant in the * Pink Beds," North Caro- | 
lina, іп rather dry oak-chestnut woods, during the latter part ог“ 
July and August. It is probable that it grows elsewhere, but has | 
been referred to L. piperata.

on the margin of the pileus. The gills are as closely crowded 
tinguish it.
