(Fr.) S.F. Grey
3.2 - 14 cm broad; convex
at first then planar
and finally depressed; margins inrolled when young, then straight,
then uplifted and finally funnel shaped at maturity, fringed at first
then naked when mature; surface usually moist to viscid
but can be dry depending on the weather, normally glabrous,
zonate with concentric darker rings; colours shades of orange, salmon
to deep to dark orange often with green stains; context 6 mm at junction
of stipe, fleshy and brittle, moist, colour yellow with some orange,
bruising green; taste mild; odour distinct, fruity.
Latex: Mild to slightly bitter tasting, carrot orange slowly becoming yellow then green.
Stipe: 3 - 5 cm long X 1.0 cm wide at apex, 0.6 cm wide at base; tapering downwards to equal; dry to moist, at times scrobiculate, brittle, unpolished, deep to dark orange; context solid at first then soon hollow, coloured as stipe surface.
This is a common species in moist nutrient rich sites in these forests.
Its characteristic flesh and lamellae
colour change from orange to green differentiates it from the other
Lactarius (L. olympianus) in these forests. L. olympianus
has white gills and latex
and does not change colour when injured. There are 4 recognized varieties
of Lactarius deliciosus, separated by the colour of the flesh
on bruising and on the presence or absence of macrocystidia.
L. deliciosus var. areolatus has no macrocystidia
and the latex
turns tissue reddish brown. L. deliciosus var. piceus
flesh and lamellae
that stain reddish brown, and is associated with Picea spp.
L. deliciosus var. olivaceosordidus has macrocystidia,
and has the flesh and lamellae
that turn green upon injury. L. deliciosus var. deliciosus,
the variety found in these forests, doesnt have macrocystidia
and the latex
turns the flesh and lamellae
