The conditionally edible and almost worldwide widespread pink- leaved or common Egerlingsschirmling ( Leucoagaricus leucothites ) is a type of mushroom from the family of mushroom relatives (Agaricaceae). It is also called the rose- leaved Egerling umbrella mushroom / mushroom umbrella . The whitish, medium-sized fruit bodies are reminiscent of a mushroom, but have white and only pale pink colored lamellae with age and an equally colored spore powder. The stem base is always without a sheath. The fruiting bodies of the saprobiontic fungus appear from August to October mostly outside of forests in gardens, parks and meadows.

features

Macroscopic features

The hat is 5–10 cm wide, bell-shaped when young, then arched and later spread out. The middle of the hat is sometimes more or less bluntly hunched. The smooth, silky-matt surface is whitish to cream-colored, the disc is often pale-ocher in color with age. The white and old pale flesh-colored to pink colored lamellae are free on the stem. They are quite thin and stand rather crowded, the spore powder is white to pale pink. The creamy white stem is 6–8 cm long and 1–2 cm wide. It is cylindrical in shape and narrowly hollow inside. Its narrow, membranous ring can be pulled off upwards. The base of the stem is thickened and can be up to 2.5 cm thick. Unlike the death cap mushrooms, it is never in a vagina. The white, firm flesh is up to 1.5 cm thick in the middle of the hat and thins towards the edge. It smells and tastes faintly mushroom-like and not very noticeable.

Microscopic features

The smooth, elliptical spores are 8–9 µm long and 5–6 µm wide. They are hyaline and thick-walled and have a germ pore. The bent-cylindrical to narrow-clubbed cheilocystidia are 40–60 µm long and 10–15 (–20) µm wide. The end cells of the cap skin are cylindrical, narrow-clubbed or spindle-shaped and measure 40–130 × 10–15 µm.

Species delimitation

The species from the Leucoagaricus leucothites complex are very difficult to delineate and the species rank and the delimitation of the individual species from one another is highly controversial. Else C. Vellinga put them all synonymously with Leucoagaricus leucothites in 2001 , only the meat-leaved Egerlingsschirmling ( L. carneifolius ) received the rank of a variety. The meat-leaved Egerlingschirmling differs in its slightly greyish and with age more brownish hat and the somewhat smaller spores (7–9 × 4.5–6 µm) and cheilocystidae (25–35 × 7–9 µm). The narrow-leaved Egerlingsschirmling ( L. densifolius ) also has yellowing flesh, its lamellas turn pink early on and later brownish. The spores are quite large with a length of 10 (–12) µm. The silky Egerling umbrella ( L. holosericeus ) has yellowing flesh and the lamellae only turn pale pink late, as in the common Egerling umbrella. Its spores are 9 (–10) µm long, the silky, matt hat is white and the end cells of the hat skin are spindle-shaped and narrow. The whitish Egerlingsschirmling ( L. subcretaceus ) immediately tan flesh and a hat skin that tears open scaly and field with age.

ecology

The fungus is often found in places influenced by humans, mostly outside of forests. You can find it in gardens and parks or on (forest) roadsides, even in greenhouses. It often occurs spontaneously after new gardens, embankments or vegetable patches have been created and usually disappears again the following year. Near-natural habitats are semi-arid and steppe lawns, farm meadows and dunes, as well as alder forests . The fungus prefers moderately to clearly nitrogenous, neutral to basic and fresh clay soils. But it also occurs on plant detritus, on compost heaps and in similar places enriched with nutrients. The fruiting bodies appear mostly from July to October, rarely earlier or later.

distribution

Legend:
green = countries with found reports
cream white = countries without evidence
light gray = no data
dark gray = non-European countries.

The fungus is distributed almost worldwide and was probably introduced into many countries. Evidence is available from Australia, New Zealand, Asia (Turkey, Israel, Armenia, West Siberia, Sri Lanka, India, Japan), America (Argentina, Chile, USA, Canada), Africa (Morocco, Algeria) and Europe. In Europe, the rose-leaved Egerling umbrella is scattered to widespread in all countries. It can be found in the north as far as central Finland and eastwards to Moscow. The fungus was still very scattered in Germany in the 1950s, but since then the species has been spreading steadily and is now very widespread in many areas. It may be a little rarer in northern Germany.

meaning

The rose-leaved Egerling umbrella is edible, but not very tasty and therefore only suitable as a mixed mushroom. The mushroom should be taboo, especially for inexperienced mushroom pickers, as it can easily be confused with the deadly poisonous white cap mushrooms. Therefore, it is classified as a non-edible mushroom in many mushroom guides.
