|Suillus granulatus (L.:Fr.) Roussel|
The cap is of a uniform colour, ranging from rusty-brown to yellow-brown or ochre with reddish shades, getting paler with age, very fleshy, of hemispherical then convex shape, eventually flattened. The cap surface is smooth, slimy when damp but shiny when dry, covered with a thick jelly layer disappearing with age, thick and entirely peelable. The cap margin is smooth, regular, inrolled when young, then expanded.The stem is firm, full, rather thin and short, covered with dots at the top and without any ring. It is whitish to lemon-yellow, with yellow or reddish-brown dots at the top, and red-brown towards the base. It is of more or less equal diameter, or slightly tapering towards the base. Like the tubes, the grainy dots exude milky droplets at the stem top.. The flesh is thick, tender and firm at first in young specimens, then soft and very spongy in the cap, the stem's flesh remaining firm. It is white to pale yellow, sometimes brownish in the stem base, unchanging to air; its taste is faint, mild, soapy ; the odour is weak and pleasant; The tubes are adnate, thin, rather short (10-20 mm). They are pale sulphur yellow then dull ochre to olivaceous. The pores are small, round to angular, pale sulphur yellow then dull ochre. They weep milky white droplets when young which remain and dry. These droplets stick to the fingers like blackish tar. The spore print is olive brown. It grows with conifers, in ventilated pine woods, pastures, parks or gardens, on a rather calcareous and sometimes acid soil, with Scots pine, maritime pine, Aleppo pine, but also spruce. The fruiting period takes place from March to December.
Distinctive features : viscous cap surface, reddish-brown to yellowish-brown; stem without ring; yellow pores, exuding milky droplets in young specimens; whitish-yellow flesh, unchanging; under pine or spruce
Suillus granulatus is quite rare and scattered in the forest of Rambouillet, and is frequent, more generally speaking .
