The Rose Red Schmierling ( Gomphidius roseus ) is a species of fungus from the family of Schmierling relatives . Due to the often yellow-fleshed stem base, it is also called rose-red yellow foot , although the second part of the name of the closely related genus Chroogomphus serves as a common name . The species forms a mycorrhiza with pines and parasitizes the mycelium of the cow tube .
features
Macroscopic features
The hat of the rose-red smear is 2–5 cm wide, initially closed in a hemispherical manner and later spread out in the shape of a funnel. The hat skin, which is only greasy and not slimy even in damp weather, is pale pink to bright rose-red in color. The lamellae that run down the stalk are whitish in the young mushroom, then pale gray and finally gray-olive in color due to the black-brown spore powder. The white stem is pointed towards the base and has a woolly thickened ring zone in the area of the lamellar attachment. The white flesh of the rose-red grease is reddish to yellowish in color at the base of the stem. It has no particular smell or taste.
Microscopic features
The spores are spindle-shaped and measure 16-21 × 4.5-6.5 micrometers. The club-like basidia with four sterigms are 50-55 micrometers long and 9-14 micrometers thick. The cylindrical cheilocystids measure 100–125 × 10–14 micrometers, the similarly shaped pleurocystids are significantly smaller.
Species delimitation
Due to its hat color, the mushroom is difficult to confuse with other species of its genus. Viewed from above, there may be a certain similarity to red Spei-Täubling like the cherry-red Spei-Täubling .
Ecology and phenology
The rose-red smear is a mycorrhizal fungus that can be found in pine forests on acidic sandy soils, where it often grows between heather. The species is often associated directly with the cow tube , whose mycelium it parasitizes .
The solitary or gregarious fruiting bodies appear in summer and autumn from around July to October.
distribution
The species is distributed meridional to boreal in the Holarctic of Europe and Asia . It does not occur in North America.
meaning
The rose-red smear is edible .
