Russula pseudointegra

The Ockerblättrige Cinnabar Russula ( Russula pseudo integra)

The Ockerblättrige Cinnabar Russula ( Russula integra pseudo ) is a species of fungus in the family Täublingsverwandten. The Täubling sees the Harten Cinnabar Täubling quite similar, but colored when ripe yellow- ocher blades. The rather rare fungus occurs in deciduous forests and is inedible.

Features

Macroscopic characteristics

The thick-fleshed hat (5 ) 10-15 cm wide. In the young mushroom he is often closed hemispherical, then convex, later expanded. The center is sometimes slightly depressed. The brim is often bent at the age wavy, hardly striate and often frosted white. The hat skin is usually uniformly colored cherry. But it can also pink sick of his scarlet to bright colored coral. Rarely, the middle is ausgeblasst yellowish or has ockerliche or orange shades on. In young fruit bodies or in the rain hat skin is slightly greasy to tacky, later dry, dull matt to silky, smooth later. You can deduct more than half.

The slats are usually quite dense, they are pale ocher young, mature deep yellow and sometimes have a salmon-colored shimmer, at the age they can darken to orange - ocher. The lamellae are grown on the stem are narrow or almost free, they are rarely forked.

The stem is 4-10 cm long and 1.5-3 cm wide shaped and cylindrical. In his youth, he is mealy, wrinkled and firm, but soon stuffed and last spongy - porous. In the age of the stem is often gray.

The fungus smells pleasantly fruity, sometimes menthol -like. Its smell reminds but sometimes also on blackberry or to the smell of Gallentäublings. The meat tastes mildly bitter but, after some chewing slightly schärflich and astringent ( astringent ). The spore powder is fed ocher (IVb after Romagnesi ).

The guaiac reaction is negative. Ferrous sulfate discolored flesh grayish and Sulfovanillin causes a bright red discoloration of the stem flesh.

Microscopic characteristics

The spores are short elliptical to almost spherical, 7-8.5 microns long and 6.5-8 microns wide. They are set with low, 0.7 micron high, line-shaped associated warts, which form a rather incomplete network. The hat skin contains no Pileozystiden, but encrusted, long and fairly wide ( 2.7 to 4 microns ) Primordialhyphen. The hyphae contain vacuoles but no membrane pigments.

The cystidia of the fins are blunt or spindle- shaped and have an amorphous sheath that surrounds the cell like a sheath, the tip remains free. The pleurocystidia are 55-80 microns long and 8.5-13 (17 ) microns wide and about 2 microns thick cell walls. The basidia are 43-60 microns long, 10-13 microns wide and have 2, 3 or 4 sterigmata.

Ecology

Like all russulas is also the Ockerblättrige Cinnabar Täubling a mycorrhizal fungus that forms a symbiosis in first line of oaks, but also like with beech trees. More rarely it goes well with other deciduous trees formed a partnership. The fungus prefers fresh, slightly acidic to slightly alkaline and moderately supplied with nutrients floors. It occurs on verlehmten brown and Luvisols and Pelosolen on different parent rocks. You can find the fungus preferably in beech and beech mixed forests, such as fir Rich Book, Orchid Book or woodruff-beech forests, and in oak mixed forests, such as bedstraw - oak-hornbeam, the heat-loving white cinquefoil - sessile oak, and the acidophilous Luzulo Hawkweed - sessile oak forests or oak-elm floodplain forests. Even in light parks, the fungus can be found. The fruiting bodies appear from July to early October. The fungus prefers the hill and the lower mountains.

Dissemination

The Ockerblättriger Cinnabar Täubling comes in North Asia before ( Russian Far East, Japan), North America (USA) and Europe. In southern Europe it is distributed from Spain to Romania and Western Europe from France to the UK. In Eastern Europe it is found in Belarus and Russia and in Northern Europe it occurs throughout southern Fennoscandia.

In Germany, the mushroom from the lowlands is widely distributed to the lower mountains. He is rare in many places and is on the red list in the category of threat RL3.

System

Infra Generic Systematics

The Ockerblättriger Cinnabar Täubling provided by M. Bon in the subsection Chamaeleontinae ( Roseinae H. Romagnesi ), a sub- section of section Lilaceae ( Incrustatae ). The subsection contains mild russulas with yellow spore powder and usually feinsamtiger hat skin. Under the microscope, encrusted Primordialhyphen and with more or less club-shaped or kopfige cuticular hyphal end cells can be recognized.

Importance

Well edible, but not tasty, roughly comparable with the Harten Cinnabar Täubling.
