LACTARIUS
LACTARIUS REPRESENTANEUS Britz. Not recommended
Figures 71, 72, page 45
PILEUS 3-6 in. broad, convex becoming plane, dull yellow, viscid, tomen-
tose, not zoned, margin at first inrolled and strongly tomentose. flesh firm,
whitish, becoming HIac. latex very abundant, at first white, then watery,
finally becoming lilac, slightly acrid, lamellae adnate, sHghtly decurrent,
close, moderately broad, dull yellowish, staining lilac when bruised, stipe
2-2 Vi in. long. %-l )4
in. thick, equal, glabrous, pruinose at the apex, tomen-
tose at the base, yellowish with brighter spots, hollow, spores white, broadly
eUiptic to subglobose, 9-11 X 7.5-9 /x, ornamented with a broken reticulum
of fairly heavy bands and a few separate warts or short ridges.
On the ground in moist woods, singly or in groups. Aug.-Sept.
This species is not common but it is a very striking fungus with the
yellow, hairy, viscid pileus and the abundant latex which becomes hlac-colored.
The spotted stipe is also a striking character. L. speciosus Burl, is similar but
has a zoned pileus and appears to be a more southern plant. The edible qualities
of L. representaneus are not known but it is not recommended because of the
acrid taste and also because other species in which the latex turns hlac such as
L. uvidus are reported to be poisonous.
LACTARIUS RESIMUS Fr. Not edible
Figure 73, page 45
PILEUS 2-5 in. broad, deeply depressed to infundibuliform, white becoming
tinged with yellow, not zonate or faintly so near the margin, viscid when moist,
glabrous in the center, margin inrolled, then spreading, whitish tomentose.
FLESH firm, white, strong odor when fresh, latex white at first, changing to
sulphur-yellow, acrid, lamellae whitish to pale cream, close, decurrent, some
forked near the stipe, stipe 1-1 )/2 in. long, Y%-Y^
in. thick, whitish with
yellowish stains or spots, equal, glabrous or pruinose above, stuff'ed becoming
hollow. SPORES broadly ellipsoid to subglobose, white, 5.5-8 X 4.5-6 ju?
ornamented with a broken reticulum of rather heavy bands and lines and
occasionally a few separate warts.
On the ground associated with aspens. July-Sept.
This is a rather large white species with a hairy margin and acrid latex that
turns yellow very quickly. No information regarding its edibihty is available
but it is not recommended because of the acrid latex.
