The watery bog deaf ( Russula aquosa ) is a fungus from the family of the deaf relatives . The rare Täubling grows in damp, swampy places in mountain coniferous forests. Other names are Fastmilder Täubling , Sumpf-Spei-Täubling and Wundroter Spei-Täubling .

features

Macroscopic features

The hat is 3–9 cm wide, arched when young, then spread out and depressed with age. The hat skin is sticky when wet and shiny to fine-grained when dry. About two thirds or more of it is removable. Under the hat skin, the hat meat is pink in places. The pink-violet, purple-red hat, often a bit brown-red to black-red in the middle, usually fades quickly and then becomes washed-out pink-blotchy. The edge is sharp, membranous, thin and translucent. In old age it is grooved to a width of about 1 cm.

The lamellas, which are quite distant and bulged to almost free on the stem, are young white and later become increasingly dirty gray-white. They are 4–10 mm wide and bulbous and rarely forked. The cutting edge is entire. The spore powder is whitish to whitish-cream in color.

The whitish, 3–9 cm long and 1–2 cm wide stem is usually thickened at the base and constricted in a characteristic way towards the stem tip. With age and moisture it becomes dirty, watery white-gray and is finally dirty brown-gray. The stem meat is stuffed with cotton wool when young, then pithy, hollow and very brittle. The stalk bark (cortex) is watery, almost hyaline, finely grooved or almost reticulate.

The meat is relatively firm only when it is young, but it soon becomes brittle and swollen. The smell is faint and indistinct. The Täubling smells vaguely of coconut and thus reminds a little of the cherry-red Speitäubling , sometimes it also smells slightly radish-like .

Microscopic features

The egg-shaped spores are 8–9 µm long and 6–7 µm wide and have very variable, 0.3 to 1.0 µm high, thorny warts on their surface. These are irregularly connected by fine lines to form a partial network. The cystids are up to 100 × 10 (12) µm long, club-like and sometimes also appendiculated .

The 6–10 µm wide pileocystids are narrowly club-shaped or stalked and usually without a septum, but sometimes simply septate. At the top they are more or less contracted. The hyphal end cells are 2–4 µm wide and otherwise have no characteristic expression.

ecology

The watery bog-deaf, like all deafblings, is a mycorrhizal fungus that primarily forms a symbiotic partnership with conifers. Its most common and most important host is the spruce . However, it can enter into a symbiosis with different types of pine. Occasionally it is associated with the cherry-red Speitäubling .

The Täubling can be found in acidic, moss-rich locations in beech , spruce-fir and spruce forests, as well as on the edges of raised bogs (pine-bog forests). It needs acidic and very moist soils that are low in bases and nutrients. The species prefers heavily silted, compacted and impermeable brown soils , pelosols , podsols and bog soils with little drainage.

The fruiting bodies appear from late July to early November, preferably in the mountainous region.

distribution

European countries with evidence of finding of the watery bog-pigeon.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries

    • With the exception of the Mediterranean countries, where the fungus is largely absent, the watery bog-deaf appears scattered all over Europe. But it's pretty rare everywhere. In North America (Canada, USA) it is common throughout the Northeast. The Täubling is a sub- meridional to sub- boreal species with a sub- oceanic focus.

    In Germany the Täubling is patchy and rare almost everywhere, only in the acidic low mountain ranges and the moor areas it is more common.

    Systematics

    According to M. Bon, the watery bog-deaf is placed within the section Russula in the subsection Atropurpurinae . The species of this group all have different colored purple, violet or reddish hats, but never pure red hats. They all taste hot and have white spore powder.

    meaning

    Like all of the Atropurpurinae pigeons , the watery peat puffin is not an edible mushroom and is at least slightly poisonous when eaten raw.
