Russula subsect. Lilaceinae is a subsection of the genus Russula , which is within the Lilacea section. The taxon Lilaceinae was defined by Melzer & Zvára in 1927 and adopted by both Romagnesi and Bon . At Bon it has the rank of a subsection and stands together with its sister taxon Roseinae in the Lilacea ( Melzer & Zvára ) Konrad section . & Joss. At Romagnesi, the taxon is a section in the subgenus Incrustatula 1987.
The type species is the red-stemmed ripe deafblings ( Russula lilacea ).
features
Macroscopic features
The representatives of the subsection are more or less medium-sized species, whose matt to fine-velvet hat can be colored red, blue or purple. In contrast to the species of the Roseinae subsection , the red-capped species have a more matt cap surface, which can sometimes be frosted or finely scaly. The main difference to the Roseinae subsection is that the stalk meat with sulfovanillin changes its color to a fleeting bluish-purple rather than reddish color. The spore powder is white and the meat always tastes mild, even in young specimens, but sometimes it can taste slightly bitter. With the exception of the white-leaved ripe-deaf ( Russula azurea ), all species grow in the deciduous forest.
Microscopic features
True pileocystidia are missing. If pileocystidia-like hyphae are found, they can never be stained with sulfovanillin or sulfobenzaldehyde . Also, no stainable milk tubes can be found in the lower cap skin layer or in the stem bark . For this, acid-fast primordial hyphae or encrusted hyphae cells occur in the cap skin . In these hyphae, a waxy layer is deposited on the cell walls that can be stained with fuchsin . During the subsequent decolorization with dilute hydrochloric acid , the dye is not released again, but remains as a granular encrustation. The hyphae of the cap skin do not contain any membrane pigments.
