The great white poplar blubber ( Russula clariana ) is a fungus from the family of the blubber relatives . Most mycologists doubt the species rank of this deafblings because it cannot be sufficiently differentiated from the aspen and the green-violet deafblings . The very rare Täubling can be found mainly under silver - but also under other poplar species .
features
Macroscopic features
The hat is 5–8 (-10) cm wide, relatively fleshy and often irregular, almost asymmetrically shaped. It is mostly purple and more greenish in color in the middle. Often the hat also has a grayish or steel blue sheen, sometimes it can also be completely greenish or olive green or have grayish spots. In dry weather, the hat skin is matt, it can be peeled off about halfway. The brim of the hat remains rolled up for a relatively long time and is not (or only very briefly and weakly) furrowed.
The relatively distant, fairly wide lamellae are first whitish, then creamy white, later they are more brownish-gray and have a cloudy cream-colored shimmer. The spore powder is pale cream-colored ( IIab after Romagnesi ).
The 3–6 (–8) cm long and 1–2 (–3) cm wide stalk is usually club-shaped and first white, then greyish. It is quite firm for the section, but it soon becomes spongy and later hollow (cavernous).
The dirty white meat tends to be gray in the handle and is relatively firm. It smells clearly of grated geranium leaves and has a very pungent taste. The guaiac reaction is positive.
Microscopic features
The spores are 8–9 (10) µm long and 7–8 µm wide. It is ornamented with burrs or a reticulated pattern. The 40–70 µm long and 6–12 µm wide cystidia are numerous and otherwise without characteristic features, possibly a little heady. The Pileocystiden are cylindrical to club-shaped, 50–100 µm long and 5–12 µm and 0–2-septate. The hyphae ends of the cap skin are about 3–5 (7) µm wide and articulated. They are more or less uniform or narrowed, twisted, sometimes knotty to thickened. The cells below are often interwoven like a puzzle.
Species delimitation
The white poplar blubber is particularly close to the aspen blubber, but its appearance is also strongly reminiscent of the green-violet blubber.
His hat is bigger and coarser than that of the Aspen-Blubber. The purple and green hat color is more reminiscent of the green-purple blubber. It differs from this, however, in that in old age it tends to be more horror than yellow. In addition, its smell is more pelargonium-like, and unpleasantly fishy when dried. Another distinguishing feature are its clearly reticulated ornamented spores and the relatively wider ends of the hat skin hyphae. However, all of these characteristics are not unique in all cases and there are all possible stages of transition between the three types.
Ecology and diffusion
Like all Bluebirds, the very rare Great White Poplar Bluebird is a mycorrhizal fungus that forms a symbiotic partnership with silver poplars and gray poplars. It is mainly found in oak-hornbeam forests and in warm-loving mixed oak forests. He seems to have a preference for heavy loamy soils.
The rare great white poplar blubber seems to be a purely European species; The Täubling has not yet been detected on other continents. Possibly the Täubling is also somewhat more common, but is not differentiated from the very similar aspen-Täubling. The species is very rare in Germany and is on the red list in many federal states , if not completely absent. It is only a little more common in Bavaria.
Systematics
Inquiry systematics
The Great White Poplar Täubling is placed in the Violaceinae section by M. Bon . The section contains sharp-tasting, rather fragile, small species, most of which have a cream-colored spore powder and often a very characteristic odor.
meaning
Like all of the Bluebirds from the Violaceinae section, the Great White Poplar Bluebird is inedible or slightly poisonous.
