Russula subsect. Laeticolorinae is a sub-section from the genus of russulas ( Russula ) provided within the section Polychroma stands. A type type is not defined.

features

The representatives of the sub- section Laeticolorinae are quite large and hard- fleshed pigeons , which, in contrast to the representatives of the sub-section Integriforminae, often have a predominantly pink or reddish colored hat, at least at the edge. The middle of the hat is often more creamy-yellow to cream-ocher in color, but without greenish, purple or brown tones. The hat can also fade out completely in older fruiting bodies. The hat skin is shiny. The meat never smells like crab or fish and is almost invariable. In old age it can sometimes turn slightly dirty brown or grayish-yellow. With iron sulfate it turns more or less pink or reddish. The aniline reaction is negative. The spore powder is ocher to yolk yellow (III-IV).

The basidia are elongated or stocky and are up to 60 µm long and 10-15 µm wide. The scattered to numerous pleurocystides are usually only weakly stained with sulfovanillin . In the cap skin there are not encrusted Pileocystiden . They are also elongated or protrude clearly from the hyphae. Pigments occur within vacuoles and not extracellularly.

Systematics

Romagnesi's R. curtipes and R. rubroalba are in the Integrinae section , while R. laeta and R. lutensis are in his Laetinae section . However, one has to point out at this point that R. borealis , which many authors consider synonymous with R. laeta , is also classified by Bon in the Laetinae subsection and that he is the R. laeta J. Schaef, which is often regarded as a collective species . interpreted in the sense of Blum.
