Features

Macroscopic characteristics

The fleshy hat is 7-12 (-15 ) cm wide, more or less curved, but often hunched irregular or lobed. He is tonbraun to pale brownish flesh, rostfalb or clay colored. The surface is smooth, slightly slippery when wet and dry otherwise. The often lighter colored edge will remain for a long time and is not rolled ribbed and without veil.

The rather forced standing and bulged deep grown lamellae are initially tonblass (but never purely whitish ) and dark in the tire after. Soon they are cafe au lait brown to ocher- colored flesh. Do not tear and their like-colored edges are jagged. The spore powder is rust brown.

The off-white, strong and rough cylindrical stalk is 5-10 (-12 ) cm long and 1-2.5 cm wide. It is hollow, without a ring and finely scaly flaky or whitish to whitish base over the entire length. The often bulbous thickened base is about 2-3 cm thick. In longitudinal section extends from Cap flesh a tapered pin into the hollow stem. The off-white, bitter-tasting meat is quite thick and strong smell of radish.

Microscopic characteristics

The almond-shaped and grobwarzig ornamented spores are 10-13 (-15 ) microns long and 6.5-8.5 microns wide and have a papillenförmigen Apiculus. The short and relatively thick Zystiden are bottle-shaped and bulbous thickened cheilocystidia often in the lower part.

Artabgrenzung

Looks very similar to the frequent Tonblasse Fälbling ( Hebeloma crustuliniforme ) from. He is somewhat lighter colored and has watery fins, which are spotted brown by the defaulting spores. The cystidia are not thickened in these Fälbling in the lower part. You can find the Tonblassen Fälbling rather outside the forest, such as in parks.

Also very similar, but much less frequently is the cocoa Fälbling ( Hebeloma theobrominum ). He too is colored smaller and more reddish brown. Its full (not hollow ) handle is not bulbous at the base, yet flaky scaly. His flesh smells slightly cocoa -like. The fungus grows preferentially in coniferous forests.

Ecology and distribution

The fruiting bodies of Flockigstieligen Radish Fälblings appear from August to October preferably in deciduous forests. He particularly likes to grow in copper beeches, rare in other deciduous trees. It is found therefore mostly available in beech and mixed forests book, in the mountains in beech / fir forests. The fungus preferably lime -and base- rich soils. The Radish Fälbling is at least locally common, but in some places declining.

System

Etymology: " Sinapizans " means " mustard -like" and is derived from the Latin word " sinapis " ( = mustard). The mustard -like odor and pungent taste is found in many species of the plant family (Brassicaceae ). It is caused by the glucosinolates, the family- typical ingredients that are responsible for the pungent radish smell and taste.

Importance

The Flockigstielige Radish Fälbling is toxic. Produce indigestion.
