Features
Macroscopic characteristics
The dünnfleischige Hat Cow Röhrlings is about four to eight inches wide and is yellow - or orange -brown. In young mushrooms it is curved, later flattened and often bent wavy. 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 Cow Röhrling has short ( ten millimeters ), slightly run-down on the handle tubes olivgelblicher color with the mature fungal relatively large mouths. They dissolve only heavy with the Cap flesh and are from two to four shorter tubes composed. The pores of the fungus are small at first and then more and elongated in old age. They are irregularly shaped and square divided in depth by septa. Their color is the hat, but they are sometimes also stained rusty brown. The length of the stem is three to six inches, and its thickness 15 mm, this is usually bent. He's tough, thin, elastic, and has no ring; its color is the yellow hat, towards the base, it is often reddish. At the base it is often grown together with other fruit bodies. The Cow Röhrling a soft, ductile and elastic mushroom meat. It is yellow in color, in hat and over the tubes, it is on average slightly blauend. In cooking, it turns pink, reddish or purple. The smell reminds a bit of fruit, it tastes sour, mild. The spore print is olive-brown powder.
Microscopic characteristics
The spores are spindle-shaped and have a size of 7-11 x 3-5 microns.
Artabgrenzung
The Erlengrübling ( Gyrodon lividus ) is similar to cow Boletus, however, is bound to alder. Even with the sand Boletus ( Suillus variegatus ), with which the cow Boletus divides the living room, there is likelihood of confusion. The sand Boletus has a grainy and filzigere hat skin that take a slimy consistency only in wet weather.
Ecology and distribution
The Cow Röhrling forms mycorrhizal with pines. Often it is therefore necessary to find from July to November in pine woodland, heaths and bogs throughout Europe, where he encounters nutrient-poor or acidic soils; However, it can also occur on calcareous soils. It is particularly common in the lowlands and appears here gregarious or tufted, rarely it is found in subalpine regions. Occurs together with the cow Boletus often the Rose Red Gelbfuß ( Gomphidius roseus) on, suggesting that the latter may be a parasite on the mycelium of Cow Röhrlings.
Importance
The cow is edible Boletus, but the taste is only moderate. He is young as a mixed mushroom or mushroom seasoning, older specimens are often eaten by pests and have soft, tough meat.
