Russula subsect. Laricinae is a subsection of the genus Russula , which is within the Tenellae section . The taxon was defined by H. Romagnesi and largely adopted by Bon. The most important features of this subsection are: 1. The representatives have yolk-yellow spore powder. 2. The flesh and the stalk do not yellow, but rather gray and 3. the deafblings form mycorrhizae with various conifers.
features
As is typical for the Tenellae section , the species are small to medium-sized and usually have wine-red to flesh-red or purple hats. The middle is often brownish or olive green in color. The mostly fragile, whitish stalk turns dirty whitish to brownish with age, sometimes also slightly grayish when watered. It will soon be hollow. The meat tastes mild or a bit pungent, especially in the lamellas. The smell is weak, but mostly not very pleasant. The fruit bodies never smell sweet like fruit compote. The spore powder is ocher yellow to dark yolk yellow. Encrusted primordial hyphae do not occur.
The mycorrhizae are characterized by more or less strongly interlocking mantle cells and sulfovanillin-positive gloeoplere cells , as is typical for the species of the Tenellae and Insidiosinae sections .
- The type species is Russula nauseosa , the ridged soft-deaf .

pine soft deaf russula cessans |
The spores measure 7.5–10 × 6.5–8.5 µm and are burr to (interrupted) network connected. Their more or less blunt warts measure 0.75–1 × 1 µm. The variably colored hat can be bright carmine red, dirty purple, reddish with copper or purple mixed tones, wine colored or purple in color. It often has a lighter or brownish center. The Täubling usually grows under pines, rarely also under spruce, the fruiting bodies usually appear late in the year. | |

Larch soft-blubber Russula laricina Velen. (1920) |
The spores 8–9.5 × 6.2–7.5 and have an ornament of unbranched pearl-like ridges that are neither reticulate nor purely isolated-prickly. The Täubling usually grows under larches, but also in spruce and fir trees. | |

Grooved soft-deaf russula nauseosa ( pers. ) Fr. (1838) |
The almost completely isolated, spiny ornamented spores measure 7–10 × 6.2–8 µm and have thorny warts 1–1.2 µm high. The hat is 2.5–6.5 wide and can be colored purple, wine-brown, purple, wine-reddish to green-olive. The Täubling grows mainly in the mountainous region under spruces, but also in firs. It prefers fresh to moist and neutral to alkaline soils. | |
