The tubes are in fruit bodies with röhrlings- , porlings- or leberreischlingsartigem hymenophore the support structure of the spore-forming fruit layer . On the enlarged surface, the fungus can produce comparatively more spores than would be possible with a smooth or missing hymenophore, for example.

Tube layer

The vertically aligned, cylindrical tubes form the tube layer on the protected underside of the hat , colloquially also called tube, sponge lining or tube sponge. In the case of the thick boletus relatives , this layer of fused tubes can easily be detached from the hat trama , in the case of the Porlingen it is thinner and firmly grown with the hat meat. The hymenophore of the liver shrimp , on the other hand, consists of individual tubes of different lengths. There are also transitional forms to the fruit bodies with a lamellar structure. For example, the European gold leaf , which belongs to the Röhrlingen, and its sister species from the genus of the Blattröhrlinge ( Phylloporus ) are characterized by fruiting bodies with often branched, strongly cross-connected lamellae, which are sometimes stunted and porous.

  • Characteristics of the tube layer

  • Whitish to dirty pink tubes of the common bile tube ( Tylopilus felleus )

  • Yellow and pronounced angular tubes of the hollow foot bolete ( Suillus cavipes )

  • Yellow tubes with red mouths of the flaky-stemmed witch's boletus ( Neoboletus luridiformis )

  • Yellowish, free and diverse long tubes of the oak liver creeper ( Fistulina haepatica )

Identifying features

The tube layer of the coniferous forest appendage boletus ( Butyriboletus subappendiculatus ) runs down the stem as a stunted net.

The tubing layer often provides important features for the fungus to specifications and Artabgrenzung . These primarily include the colors of the tubes, tube mouths and the tube bottom. Depending on the age of the fruiting bodies, differences can also occur here. It is also important whether the layer changes color when you press it. The shape (for example round, polygonal or labyrinthine) and the diameter of the tubes can also be decisive. In addition, analogous to the lamellar mushrooms , there are differences in the transition at the base of the hat: The tube layer is either free, almost free, clearly bulged or just grown, but can also run down the stem. With some tubes, the tube layer merges seamlessly into the stem network, so that one can definitely speak of stunted tubes with the meshed structure.
