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

features

This subsection combines fragile species, with red or pink colored hats, which often discolor with age and can then become whitish or yellowish. The stem is pure white. The spore powder is also white to whitish. The mushrooms in this subsection always taste very hot. The hat skin is usually sticky and shiny when it is wet and silky matt when it is dry. The smell is more or less strong, but always pleasant. The pigeons in this subsection usually smell fruity, sometimes coconut or honey-like.

The cap skin contains pileocystides which can be stained with sulfobenzaldehydes such as sulfovanillin . Acid-resistant incrustations do not occur.

Systematics

The Emeticinae subsection of Romagnesi and Bon largely match. Romagnesi only places the yellow blotchy blotch in the Persicinae subsection , a taxon that Bon lacks. Romagnesi's classification makes sense, since the yellow-spotted deafblings are very different from the other Spei-deafblings from the subsection.

At Singer , the taxon Emetica has the rank of a strip and also contains the species complex around the alternately colored deaf russula fragilis and the lacquered deaf russula laccata , syn .: R. norvegica .

At Sarnari the species are in the Russula subsection , which corresponds to the newer taxonomic rules, as this subsection contains the type species of the genus. However, the subsection Russula combines Bons subsections Emeticinae , Citrinae and Atropurpurinae . Sarnari divides its subsection further into the series Russula and Atropurpurea . His Russula series largely corresponds to Bon's sub-section Emeticinae , but also contains the pale yellow deaf russula raoultii , while the birch pigeon Russula betularum is part of his Atropurpurea series . Moving the birch pavilion to the Atropurpurea series does not seem to make sense, as both the mycorrhizal anatomy and molecular biological data clearly show the close relationship to the cherry pavilion. It makes sense to place the deaf in the Russula series (in Bon this deaf is in the Citrinae subsection ). The pale yellow blubber has many features in common with the Emetica group, only its yellow hat color distinguishes it from the other species in this subsection. But also the birch and beech-Spei-Täubling have the property to fade and then also show yellowish tones. This is why the pale yellow blubber fits better into the Russula subsection , especially since the R-DNA analysis speaks for it.
