The Ringlose butter or mushroom Boletus Ringlose butter or Rosafüßige grains Boletus ( Suillus collinitus, syn. Suillus fluryi ) is an edible mushroom of the family of Schmierröhrlingsverwandten. He is often found under pines with which it forms mycorrhiza.

Features
Macroscopic characteristics
The hat of the Ringloze butter mushroom is about 3-10 cm wide and is bright, yellow, red or dark brown. In young mushrooms it is curved, flattened later, the edge is smooth, sometimes wavy bent. It is coated with a lubricant for the boletes typical, sticky and greasy skin that gets a slimy film in damp weather. The brim is initially rolled and sharp in older mushrooms. The pores of the fungus are rounded to angular, and are initially pale yellow, olive yellow colored later. The stem is 4-7 cm long and up to 2 cm wide, yellowish, covered with red or brown scales. The stem base and the Myzelfilz are colored pink. He does not have a ring. The flesh is yellow and has a soft, chewy and elastic consistency. It turns more gray than greenish with potassium hydroxide solution and salmon pink with iron sulfate. The spore powder is light brown.
Microscopic characteristics
The spores are elliptical to apple core shaped, yellowish, with drops and have a size of 7.5-10 × 3:2-5 microns.
Artabgrenzung
The Ringlose butter mushroom is very similar to butter Boletus (p. luteus ), with whom he also shares the location under pines. However, this has a whitish ring ( velum ) on a stick. Even with the Sandröhrling ( Suillus variegatus ) a likelihood of confusion. However, the Sandröhrling has a grainy and filzigere hat skin that takes a slimy consistency only in wet weather. In the Mediterranean region, it can also be confused with the Mediterranean Boletus.
Ecology
The Ringlose butter fungus forms mycorrhizal with pines and is also used for reforestation in Mediterranean areas. It grows rarely in forests, but usually only at the edges. It occurs mainly in pine forests, oak thickets. Most commonly it grows in the transition zone between pine forests and pine forests and juniper heath, sometimes on park-like locations and in meadows and pastures. The Ringlose butter mushroom is found in Central Europe on calcareous soils. The fruiting bodies appear in Central Europe of seldom in summer, rather later in the year (September to October), up to the first frosts.
Dissemination
Whether the Ringlose butter mushroom in North Africa occurs is unclear, it might be there, also be confusion with the Mediterranean Boletus. At least in Spanish Mittelmeergebietund Malta it is very common and is often the dominant Großpilzart in Aleppo pine stands. The species is otherwise throughout Europe as far north as central Sweden and east to Slovakia before. In Germany it is common in the south, but lacking the north of the 52nd parallel largely.
Importance
The Ringlose butter mushroom is edible, but the taste is only moderate, older specimens are often eaten by pests and have soft, tough meat.
