Trametes Troga (Trametes Trogii) is a spongy parasitic fungus. Belongs to the Polyporov family and the large genus Trametes. Its other names:
- Cerrena Troga;
- Coriolopsis Troga;
- Trametella Troga.
What does Troga’s trametes look like?
The annual bodies of Troga’s trametes have the form of a regular or wavy, rather fleshy semicircle, thoroughly adherent to the substrate with a flat lateral part. In mushrooms that have just appeared, the edge of the cap is distinctly rounded, then becomes thinner, becoming sharp. The length can be different – from 1,5 to 8-16 cm. The width from the trunk to the edge of the cap is 0,8-10 cm, and the thickness ranges from 0,7 to 3,7 cm.
The surface is dry, covered with thick, long cilia-bristles of golden color. The edge of young specimens is velvety, with a pile, of overgrown specimens – smooth, hard. Implicit concentric stripes, slightly embossed, diverge from the place of growth. The color is grayish-white, yellowish-olive and brown, brown-golden and slightly orange or rusty red. With age, the hat darkens, becoming a honey-tea color.
The inner surface is tubular, with distinct large pores from 0,3 to 1 mm in diameter, irregular in shape. First rounded, then they become angular-toothed. The surface is uneven, rough. Color from bright white to cream and gray-yellowish. As it grows, it darkens, becoming the color of coffee with milk or a pale lilac shade. The thickness of the spongy layer is from 0,2 to 1,2 cm. The spore powder is white.
The flesh is whitish, changing color as it matures to creamy gray and pale tawny olive. Rigid, cork-fibrous. The dried mushroom becomes woody. The smell is sourish or pronouncedly mushroom, the taste is neutral-sweet.
Trametes Troga can be evenly procumbent with bent folded edges or inverted spore-bearing sponge outwards
Where and how to grow
Trametes Troga prefers to settle on hardwoods – both soft and hard: birch, ash, mulberry, willow, poplar, walnut, beech, aspen. It is very rare to see it on pine trees. The mycelium of this species is perennial, fruiting bodies appear annually in the same places.
The mushroom picker begins to actively bear fruit from mid-late summer until a stable snow cover. They grow singly and in large colonies, located in the form of tiles and side by side, you can often find ribbons from these fruiting bodies fused with sidewalls.
Prefers sunny, dry, wind-sheltered locations. It is ubiquitous in northern and temperate latitudes – in deciduous forests and taiga zones of Our Country, Canada and the USA. Sometimes it can be found in Europe, as well as in Africa and South America.
This species destroys host trees, causing a rapidly spreading white rot.
Is the mushroom edible or not?
Trametes Troga is an inedible species. No toxic or poisonous substances were found in its composition. The tough, woody flesh makes this fruiting body unattractive to mushroom pickers. Its nutritional value is extremely low.
Twins and their differences
Trametes Troga is similar to the fruiting bodies of its own species and some other tinder fungi.
Trametes is hard-haired. Inedible, non-toxic. Can be recognized by small pores (0,3×0,4 mm).
Long bristly villi are white or cream in color
Fragrant trametes. Inedible, not poisonous. It is distinguished by the absence of pubescence on the cap, a light, gray-white or silver color and a strong smell of anise.
Prefers loose poplar, willow or aspen wood
Coriolopsis Gallic. Inedible mushroom. The cap is pubescent, the spongy inner surface is dark-colored, the flesh is brown or brown.
It is easy to distinguish from Trog’s trametes due to its darker coloration.
Antrodia. Inedible look. Their main difference is coarse-meshed pores, sparse pubescence setae, and white flesh.
This large genus includes varieties recognized as medicinal in the folk medicine of the East.
Conclusion
Trametes Troga grows on old stumps, large fallen trees, as well as damaged living trunks of hardwoods. The fruiting body develops during the autumn season and is able to survive the winter. It lives in one place for many years – until the complete destruction of the carrier tree. Can be found in the Northern and Southern Hemispheres. Widespread in Our Country. In Europe, it is listed as rare and endangered species. The mushroom is inedible due to the hard, unattractive pulp. No toxic species were found among the twins.
