Summer Oak Boletus Mushroom

The summer or oak boletus (Boletus reticulatus, syn. B. aestivalis) is a species of mushroom from the family of the large boletus relatives. It is considered an edible mushroom and can be found as early as May.  The summer boletus is a European species, but is also said to have been found in Australia. Northward it occurs as far as central Sweden and central Finland, eastward it has been found as far as Katowice in Poland. The summer boletus is a popular edible mushroom.

Like all members of the genus Boletus, it is protected in Germany and may only be collected in small quantities for personal use. The fungi (Fungi) form the third major kingdom of eukaryotic organisms along with the animals (Animalia) and the plants (Plantae). Like plants, to which they have long been classified, they are sedentary, but they cannot photosynthesize. Therefore, like animals, they must feed by ingesting organic substances (heterotrophy), but they absorb them in dissolved form from the environment.

According to current knowledge, fungi are more closely related to animals than to plants. They include mainly multicellular organisms such as the stander fungi, but also unicellular organisms such as baker's yeast, as well as coenocytic forms with many cell nuclei but without cellular subdivision. The science that deals with fungi is called mycology.
