The granule bolet or loach ( Suillus granulatus ) is an edible mushroom belonging to the relatives of the bloom . It is mycorrhizal partner of all two-needle jaws . A finely granulated (Latin: granulum = grain) stem surface is striking . Young specimens in particular often show droplets of liquid on their stems and tubes.

Macroscopic features
The granule tubular has an initially hemispherical, later flattened hat with a diameter of up to 15 cm. The hat skin is not or only slightly blotchy, when wet it is greasy, sticky and can be easily peeled off. The brown color fades to yellowish-brown with age. On the underside of the hat there are small, close-fitting tubes that have grown slightly to the stem and run down slightly. They are pale yellow, later lemon to yolk yellow, and show no color change when printed. The spore powder is brown to ocher-brown. The ringless stem becomes 4 to 10 cm long and 1 to 2 cm thick. Mostly it is cylindrical or slightly tapered towards the base. The yellowish-white surface of the stem is covered with grains of the same color (name!). The pores are the same color as the tubes, are narrow, somewhat irregularly warped or angular. In young specimens, a milk-colored liquid emerges from them, which shows up in small guttation droplets . The flesh is white-yellowish, at first firm, but later very soft and spongy. The smell is weak, but pleasantly sour, fruity and mild.
Microscopic features
The spores are elliptical and 10 × 4 micrometers in size.
Species delimitation
As a rule, it cannot be confused with poisonous species. It can at best be confused with related species, but this does not usually pose a health risk, as all these mushrooms are edible.
The ringless butter mushroom ( Suillus collinitus ) is similar . It is distinguished by a darker, ingrown radial-fiber hat, pink hues on the base of the stem and mycelial felt and clear to yellowish guttation droplets.
The butter mushroom ( S. luteus ), the golden boletus ( S. grevillei ) and the Helvetic bolete ( S. sibiricus ssp. Helveticus ) are easy to distinguish by their stem ring.
Resemblance also have the Suillus bovinus ( p bovinus ) with larger diameter pores, the suillus plorans ( p Plorans ) with other colors and an occurrence in pineal pines and Suillus variegatus ( S. variegatus ) with fine scales dotted hat.
Distribution and ecology
The granule boletus is distributed over the entire northern hemisphere and is considered common in Europe . It accompanies the two-needle pine species from the sea coasts to the alpine zones, and appears there from June to October. The granular boletus always occurs on alkaline soils ( limestone ground ) and is more common in the south than in the north. Preferred locations are clear areas, parks, forest edges and sheep pastures. Occasionally, the Rönchenröhrling occurs in company with the copper-red smear , which is also an excellent edible mushroom and is also only associated with pines.
meaning
The kernel bolete is a very good and rich edible mushroom . However, it is advisable to collect only younger specimens, if necessary peel off the greasy and sticky skin of the hat while collecting. The Rökchenröhrling is suitable fried or steamed for single or mixed mushroom dishes. But also very good for drying, where it develops a fine, buttery aroma. Together with chestnuts, porcini mushrooms and other felt boletus, the boletus is very suitable as a mushroom insert in risotto ai funghi or for mushroom tarts. Because of its greasiness, the tubular pellets are not suitable for soaking in oil or vinegar.
However, it should be noted that it can be difficult to digest. Individual intolerance reactions are possible.
