The mushrooms have a smooth, whitish to yellowish, truffle -like fruiting bodies. The whitish gleba ruled in violation of a milk.

Features

Macroscopic characteristics

The soft, underground in the soil growing ( hypogeous ) fruiting bodies are more or less spherical to irregularly lobed and 1-5 cm high and wide. The gleba is white and shows little labyrinthine, -tube chambers that are filled 0.25-0.50 mm wide and with spores, which are embedded in a gelatinous mass. With an injury to Gleba exudes a whitish milk. A columella is not formed. ( A sterile columella is the central axis, which can be found inside many belly mushrooms. ) The peridium, it is called the outer shell, is well developed and its surface is whitish to pale yellowish or ocher -yellow to brown. It is different from thick and discolored pink by potassium hydroxide, burgundy or purple. The fruiting body usually have a strong odor.

Microscopic characteristics

The 10-22 microns long as wide, hyaline spores are more or less rounded and have no Apiculus. The surface is warty to spiny and surrounded by an outer gelatinous membrane. The spores can not be stained with Jodreagenzien are so inamyloid. The clavate to cylindrical or constricted basidia are 30-60 microns long and have two or four sterigmata. They arise within the gleba in a disorganized hymenium and dissolve at maturity on. The Hyphensystem is monomitisch. Zystiden or buckles do not occur. The Ectomycorrhizapilz grows underground in the ground or in the leaf or needle litter, in some cases, the fruiting bodies can look out a little from the ground.

System

The genus Leucophleps 1899 defined by the American mycologist Harvey Willson Harkness. An optional homonym is Cremeogaster, a name coined by Oreste Mattirolo.

Worldwide, there are about 8-10 species in Europe only Leucophleps aculeatispora, the European white truffles and veins Leucophleps magnata occur.
