Collibia tuberous has several names: Gymnopus tuberous, Amanita tuberous, Microcollibia tuberous. The species belongs to the Tricholomov family. The variety parasitizes on decomposed fruiting bodies of large tubular fungi: saffron milk mushrooms or russula. Refers to toxic inedible species.
What does Collibia tuber look like?
This is the smallest member of the family, having a white or cream color and characterized by bioluminescent ability (glows in the dark). The hymenophore is well developed, has a lamellar structure.
Cap Description
hat shape:
- in young specimens it is convex – 20 mm in diameter;
- flat-convex as it grows, with a noticeable depression in the middle;
- the edges are even or concave, the color is lighter than the central part;
- the surface is smooth, hygrophanous, transparent, with defined radial bands of spore-bearing plates;
- plates do not protrude beyond the cap, are rarely located.
Description of the leg
The leg of Collibia is tuberous thin – up to 8 mm wide, grows up to 4 cm in length:
- shape is cylindrical, tapering at the top;
- the structure is fibrous, hollow;
- upright or slightly curved at the base;
- the surface is even, with a white felt coating near the cap;
- the color is light brown or yellow, darker than the upper part of the fruiting body.
Collybia tuberous is formed from sclerotium in the form of an oblong rounded body, which consists of woven mycelium. The color is dark brown, the surface is smooth. The length of the sclerotium is within 15 mm, the width is 4 mm. Has a luminescent property.
Is the mushroom edible or not?
Collybia tuberous is toxic. Gymnopus can only grow on the remains of large mushrooms with a high protein content. When decomposed, the substance releases toxic compounds. In the process of symbiosis, collibium accumulates them and becomes poisonous to humans. It has an unpleasant odor and an unaesthetic appearance.
Where and how to grow
The area of distribution of Hymnopus tuberous directly depends on the growth sites of lamellar large species with thick pulp. Gymnopus is not a rare specimen; it is found from the European part to the southern regions. It parasitizes old decayed mushrooms. Forms small families from August until the onset of frost.
Twins and their differences
Twins include Collybia cirrhata (Curly Collybia). Saprotroph grows on the blackened remains of milk mushrooms, giant miripulus, mushrooms.
Outwardly, the mushrooms are similar, Collybia cirrhata is larger, less toxic, it lacks sclerotia. The base of the leg is covered with a long white pile. The edges of the cap are wavy. Mushroom tasteless and odorless, inedible.
The surface of the leg with a small, dense, white pile. The doppelgänger is inedible.
Conclusion
Collibia tuberous is a small, inedible culture containing toxins in its chemical composition. It grows on the remains of large fruiting bodies from late summer to mid-autumn. Distributed throughout the temperate zone.
