Russula subsect. Indolentinae is a subsection of the genus Russula , which is within the section Heterophyllae .

features

The subsection contains quite large representatives from the very diverse family of the female deaf. The meat does not react with FeSO 4 or only becomes very slowly and indistinctly green. The stem is white or slightly tinged with purple. The spore powder is white to creamy white. The lamellas are - quite atypical for the genre - soft and pliable. Sometimes they can also taste slightly spicy. The dermatocystids are very narrow with a width of only 2–4 µm.

Systematics

From Romagnesi , Singer and Sarnari Women Täubling is R. cyanoxantha as part of the subgenus Heterophyllidia (or Heterophyllae or section Heterophyllae ) seen. But despite a macroscopically similar appearance, the subsection Indelentinae shows clear differences in their hat skin anatomy and in their macrochemical reactions. DNA analyzes show that the subsection Indolentinae is a sister taxon to the section Heterphyllae , which stands between the Heterphyllae and the section Ingratae . The mycorrhizal anatomy also speaks in favor of separating this subsection as a separate section, as it shows no closer relationship to the other representatives of this section.
