Russula subsect. Sphagnophilinae is a subsection of the genus Russula , which is within the Tenellae section .
features
The representatives of the subsection are medium-sized, almost sturdy or fleshy pigeons, which often have a grooved brim. The species yellow only weakly. They have no odor or smell slightly fruity, but hardly pleasant. The collapsible stem is sometimes tinged pink or reddish. The spore powder is cream-colored, ocher and rarely slightly yellow in color, but never darker than IVab ( according to Romagnesi ). The hats are very variable in color. They can be purple, purple, pink-flesh-colored or greenish in color. The pigeon can be found mostly under deciduous trees, especially under birches.
The cystidia reach 80 (90) µm in length, the taxon thus forms a transition to polychromae . The spores are also quite large, reaching 10-11 µm or more.
- The type species is Russula nitida Fr. der Milde glosstäubling .
Systematics
The taxon is only used by Romagnesi and Bon. In Sarnari and Singer (at least in his latest revision of the system) the taxon is missing, the species are here within the Urentes subsection . Molecular genetic work by Miller et al. were able to show that the taxon forms its own lineage, which is at some distance from the other subsections of the Tenellae section .
