Russula subsect. Roseinae is a subsection of the genus Russula , which is within the Lilacea section. (Section Incrustatae or sub-genus Incrustatula at Romagnesi.) The subsection was originallydefinedby Rolf Singer , but onlyvalidly describedin 1998 by Mauro Sarnari .
The type species is Russula aurora (synonym: R. velutipes ), the fuzzy pink-blotchy .
features
The representatives of the subsection are mostly medium-sized to smaller species, whose hats are usually reddish or salmon-colored to pink, sometimes sometimes orange. The middle can sometimes fade more or less off-white. Purple, bluish or olive green tones never appear. The hat skin is often frosted or velvety and usually more or less grown and often difficult to remove. The stem is usually white, but sometimes also tinged with pink. With sulfovanillin, the stalk meat turns lively and permanently eosin red , especially on dried herbarium . In fresh specimens, the tip of the stem often only turns pink. The meat turns bluish with guaiac . The spore powder is whitish to creamy white.
The skin of the hat contains primordial hyphae , i.e. hyphae on the cell wall of which a waxy layer is deposited that can be stained with fuchsine and does not give off the dye again when it is subsequently decolorized with dilute hydrochloric acid. Pileocystides , however, could not be detected. The pigeons form a mycorrhiza predominantly to exclusively with deciduous trees.
Mycorrhizal Anatomy
The ectomycorrhizae are regularly monopodially branched and light red-brown in color with a smooth surface. The outer mantle layers are pseudo- parenchymatic , that is, they consist of irregularly shaped, puzzle-piece interlocking cells. The gloeoplere cells, that is, hyphae with an oily yellowish content, turn a pale grayish color with sulfovanillin. The hyphae consists of antler-like, branched hyphae, with a few needle-shaped outgrowths that are embedded in a gelatinous matrix. All septa are simple, there are no buckles.
