Mushroom of deciduous stumps or stumps that is characterized by its yellow ocráceo color, its growth in large groups, its big size mazudo and its foot with membranous ring. Because of its bitter taste, it has no culinary interest. SOMBRERO from medium to large, at the beginning of the hemisphere and then convex, fleshy and very regular.
5 to 15 cm in diameter, with a dry surface, covered with fine fibrous scales a little darker than the bottom, ocher yellow or live ferruginous ocher. PIE thick and usually thickened in a bulb at the base, often slightly curved by its development in bouquets, 8 to 10 cm x 1 to 2.5 cm in the center with dry, yellow surface clear or yellowish white and provided with a membranous ring in the upper third that stains ocráceo by spores. CARNE compact and hard, white yellow or yellow, with no special odor and a clearly bitter taste. Under the hat there are thin, rather tight sheets, adnatas or a little cut at the foot of the yellow okra and then ferruginous by the spores.
It develops on stumps or dead trunks and in decomposition of beech or oak and also of conifers, in beech and oak as well as in pine forests or also collected in alerzales.
A typical fall fruit species, from September to November.
