Description
Ecology: saprophyte on the remains of deciduous or, less often, conifers. Causes white rot. Grows singly or in small groups on stumps, fallen trees, sometimes on rotting wood shallowly submerged in the soil.
Hat: 1-2.5 centimeters in diameter. In youth it is broadly conical; with age it becomes broadly convex to flat, sometimes with a central tubercle. Wet, shiny, smooth. Young specimens look a little wrinkled, especially in the center of the cap; these wrinkles are somewhat reminiscent of a venous pattern. With age, wrinkles straighten. The edge of the cap may be finely ribbed. The color of the cap is bright yellow, golden-yellow in youth, dims with age, acquiring brownish-yellow tones, but does not completely go brownish, there is always a yellow tint. The edge of the cap looks darker, brownish due to the very thin, almost translucent flesh at the edge of the cap.
Plates: loose, frequent, with plates (rudimentary plates). In youth, for a very short time – white, whitish; when ripe, the spores acquire a pinkish color characteristic of all spitters.
Leg: 2-5 centimeters long. 1-3 millimeters thick. Smooth, fragile, smooth. Whitish, pale yellow, with white cotton wool of the basal mycelium at the base.
Ring: missing.
Flesh: very thin, soft, fragile, slightly yellowish.
Smell: slightly distinguishable, when rubbing the pulp, it resembles the smell of bleach. Taste: no particular taste.
Spore Powder: Pink. Spores: 5-7 x 4.5-6 microns, smooth, flowing.
Season and distribution
It grows from late spring to early autumn. Found in Europe, Asia, North America. It is possible that Plyutey golden-veined is widespread throughout the globe, but it is so rare that there is no exact distribution map yet.
Edibility
No data on toxicity. P. chrysophlebius is probably edible, like the rest of the Pluteev genus. But its rarity, small size and very small amount of pulp does not dispose to culinary experiments. We also remind that the pulp may have a weak, but rather unappetizing smell of bleach.
Similar species:
- Pluteus chrysophaeus is slightly larger with brownish tints.
- The lion-yellow roach (Pluteus leoninus) is a roach with a bright yellow hat. Differs in much larger sizes. The hat is velvety, there is also a pattern in the center of the hat, but it looks more like a mesh than a pattern of veins, and in the lion-yellow spit, the pattern is preserved in adult specimens.
- Pluteus fenzlii is very rare. Its hat is bright, it is the yellowest of all yellow spitters. Easily distinguished by the presence of a ring or annular zone on the stem.
- Orange-wrinkled roach (Pluteus aurantiorugosus) is also a very rare roach. Differs in the presence of orange shades, especially in the center of the cap. There is a rudimentary ring on the stem.
Notes
There was some taxonomic confusion with Plyute golden-veined, as well as with Golden Spit (Pluteus chrysophaeus). North American mycologists used the name P. chrysophlebius, European and Eurasian ones – P. chrysophaeus. Research carried out in 2010-2011 confirmed that P. chrysophaeus (Golden Plyutey) is a separate species with a darker, more brown cap color.
The situation with synonyms is also ambiguous. Synonym for 'Pluteus chrysophaeus' North American tradition called 'Pluteus admirabilis'. Recent research confirms that 'Pluteus admirabilis', named in New York in the late 19th century, is actually the same species as 'Pluteus chrysophlebius', named in South Carolina in 1859. Justo's research recommends that the name 'chrysophaeus' be dropped altogether, as the original 18th century illustration of the species shows a mushroom with a brown rather than a yellow cap. However, Michael Kuo writes about finding (very rarely) populations of Pluteus chrysophlebius with brown caps and yellow caps growing together, photo:
and thus the 'chrysophaeus' issue for North American mycologists is still open and requires further study.
