Trihaptum biforme is a mushroom from the family Polyporaceae, belonging to the genus Trihaptum. It is considered a widespread species. Grows on fallen deciduous trees and stumps. Causes the appearance of white rot, which accelerates the process of wood destruction.
What does Trihaptum ambiguus look like?
The mushroom consists of numerous caps forming a semicircular imbricated group. Cap diameter – up to 6 cm, thickness – up to 3 mm. In young specimens, the surface is pubescent, resembling felt, and over time becomes smooth and silky. The color of the cap can be brownish-green, ocher, or light gray. In some representatives, the outer edge has a light purple color. If the weather is dry and sunny, the surface fades, becoming whitish.
Concentric striping is visible on the cap
The fruiting bodies of the hymenophore are purple-violet in color. There is an intensification of the shade at the edges.When damaged, the color does not change. In older specimens, the lower part of the cap becomes dull, becoming brownish-yellow or brown.
The mushroom has no stem.
The inner part is hard, painted in a light, almost white shade.
The color of the spore powder is white.
Where and how does it grow
This representative of the fungal kingdom is a saprotroph, so it grows on dead wood and stumps. Prefers deciduous trees. Most often, Trihaptum dwarf chooses birch, but can also be found on alder, aspen, hornbeam, beech, and oak. It practically does not grow on coniferous trees.
The distribution area of mushrooms is very wide. In Russia they are found everywhere: from the European part to the Far East. They prefer a temperate climate; they grow very rarely in the tropics.
The appearance of Trihaptum duplicum is accompanied by white rot on the wood. This leads to its rapid destruction.
Fruits from July to October.
Is the mushroom edible or not?
Trihaptum ambiguus is classified as inedible. Its pulp is too hard and has no nutritional value, so mushroom families are not collected and used for cooking.
Doubles and their differences
Trihaptum ambiguum has several similar varieties. It is very easy to confuse them if you do not know some of the features of their growth and structure. Doubles can be called:
- Trihaptum spruce - a smaller representative of the fungal kingdom, growing in rows or groups on coniferous trees. The hats of this subspecies are monochromatic and gray in color. The pubescence on them is more noticeable than on the double representative. The purple color of the hymenophore is well expressed and lasts a long time.
- Brown-violet varietyb (Trichaptum fuscoviolaceum) also resembles a dual species.Important! The main difference is the place of growth.
This species is found only on coniferous trees. It can be recognized by its hymenophore, formed in the form of radially diverging teeth, which at the edges are transformed into jagged plates.
- Larch subspecies has slight pubescence and a light gray, whitish color of the cap. Found in coniferous forests, prefers larch. It can also be found on other conifers. The hymenophore is formed from wide plates. Due to the rigidity of the fruiting body, it is not suitable for use as food.Attention! Classified as inedible.
Conclusion
Trihaptum ambiguus is an inedible representative of the mushroom kingdom, widespread everywhere. Selects fallen trees and deciduous stumps for growth. It has several inedible counterparts, differing in habitat and external characteristics. The fungus provokes the appearance of white rot, which destroys the wood.
