The soft blubber ( Russula mollis , Syn .: Russula olivascens auct. Pp) is a fungus from the family of the blubber relatives (Russulaceae). It is a fairly small deaf with mild-tasting, slightly graying flesh and ocher-yellow spore powder. The hat is colored yellow green or olive green. The very rare Täubling grows in the deciduous forest near hornbeams or linden trees.

Macroscopic features

The rather fleshy and frail hat is 4–6 (7) cm wide, first arched and then spread out flat. The hat skin is more or less shiny and colored predominantly green, yellow-green or olive-green. The middle of the hat is sometimes more intensely colored, the edge can be more washed out in purple or spotted with reddish spots.

The lamellas are bright yellow in color and often have an orange tinge. The spore powder is ocher yellow ( IVbc according to Romagnesi ).

The rather cylindrical, white stem is 5–8 cm high and 1 (1.5) cm wide. Below the lamellas, it can be slightly widened. After touching or when moistened, the handle turns white-gray. The flesh is also white and can be more or less gray. The smell is slightly fruity, with age it is also sweet, honey-like and sometimes almost unpleasant. The guaiac reaction is positive, with iron sulfate the meat turns a dirty gray.

Microscopic features

The spores are about 7–9 µm long and 5.5–7 µm wide. They are covered with spiky warts up to 1 µm high, which are fairly isolated, but are sometimes sparsely connected by fine lines.

The up to 85 (100) µm long and 8–10 (12) µm wide cystidia are not very characteristic, they are sometimes somewhat elongated and more or less spindle-shaped. The hyphae end cells of the hat skin are 2-3 (5) microns wide, cylindrical or slightly clavate to be constricted. The tip is more or less nipple-shaped. The primordial hyphae are 4–5 (7) µm wide, and have no special features, the incrustation is more or less unstable. The subcutis is filamentous. Caulocystid and laticifera can be stained with sulfobenzaldehyde.

Species delimitation

The yellow-green leather blubber ( Russula luteoviridans ) looks very similar, but is usually much larger and also grows in coniferous forests. The green discolouring deafbling ( Russula postiana ) is very similar , but it normally grows under spruce trees in mountain coniferous forests, has larger spores and also differs in the anatomy of its cap skin.

Ecology and diffusion

The mycorrhizal fungus is said to be preferred in deciduous forests with hornbeams and linden trees and is quite chalk-loving. The very rare deafling has been found in Bulgaria, France, Germany, Denmark and the Ukraine.

Systematics

Russula mollis was first described in 1883 by the French mycologist L. Quélet. The species was interpreted very differently by later authors. Many authors have synonymous the deaf with Russula olivascens , others consider it synonymous with Russula luteoviridans G Martin , which is in turn interpreted differently. Russula mollis is understood here in the sense of Romagnesi.

Inquiry system

Romagnesi places the deaf in its section Polychromae and there in the subsection Integroidinae . With Bon, the deaf is also in the subsection Integroidinae , but it is in the section Lilaceae . The Soft Täubling is the smallest representative of the subsection, whose representatives always have mild-tasting meat and ocher-yellow spore powder. The hats can be colored very variably.

meaning

As a mild-tasting Täubling, the soft Täubling is probably edible.
