features
Macroscopic features
The hat reaches 5–12 cm in diameter, the hat skin is gray to gray-brown, coarse silver to dark gray scales (mackerel). The edge is rolled up when it is young. The relatively wide lamellas are dirty whitish, stand crowded and bulge out. Especially in young fruiting bodies, they are often covered with water droplets (watery). The whitish stalk becomes 12 cm long, is compact and has rust spots at the base. Its shape is bulbous to club-like. The tip of the stem is covered with droplets. The rough meat is firm, full and has a strong odor of flour. The spore powder is white.
Microscopic features
The oval shaped and smooth spores of the tiger knight are colorless and translucent . They measure 8-10 × 6-7 micrometers .
Possible confusion of Tiger Ritter compact with edible mushrooms consist inter alia against Schwarzfaserigem Ritterlingsartige (including no flaky pileus), Gilbendem Erdritterling (including Yellow-edged leaves) and Erdritterling (including no flour smell).
toxicology
When taken orally, the tiger knight causes the so-called gastrointestinal syndrome , which is characterized primarily by effects on the digestive system. Although chemical evidence of a certain toxin has not yet been found, the toxic effect is undisputed. Ingestion can lead to severe discomfort with vomiting, diarrhea, but leaves hardly any traces. However, death from circulatory failure and excessive water loss cannot be ruled out as a result of poisoning.
ecology
The tiger knight is a mycorrhizal fungus from various deciduous and coniferous trees, primarily red beech , silver fir and spruce . The mycelium grows in the earth. The fruiting bodies appear from August to October and certainly form witch rings . The tiger knight occurs all over Europe. It only lives in calcareous soil, which is why it is only found scattered more often, in Germany especially in the south and in southern Mecklenburg. In general, the fungus is rare.
