Equestrian Tricholome, Tricholoma equestre, is a pioneer mushroom, one of the first to colonize the sandy forest soil of coastal pine forests. This Basidiomycète from family of Tricholomataceae is reported as toxic from a decade.

Description of equestrian tricholoma

The hat of the equestrian Tricholome is first convex and then it spreads out, thus measuring between 4 and 10 cm in diameter. Its color tends towards olive-yellow and golden yellow, eventually taking on a yellow-brownish hue. As we age, the surface of the hat, which is initially smooth, especially in the center, will be covered with brown to reddish strands. The more or less wavy margin can sometimes be streaked. Beneath it, the bright yellow blades are wide and tight. With age they can evolve towards colors of a paler yellow.

The thick, stocky foot, usually wider at the base, is represented by heights of between 3 and 10 cm. Bright yellow it can sometimes sport wicks similar to those of the hat. The flesh of the whole is thick and quite firm. It is white but more yellowish in the foot. It has a mild to mealy flavor and a weak or slightly mealy odor.

Determination of equestrian Tricholoma

Many identification errors can be made between Tricholoma equestre and other tricholomas and cortinates. Especially with the toxic Sulfur tricholoma, Tricholoma sulphureum which nevertheless grows most often under deciduous trees.

Two species sometimes found in the same environments can also lead to confusion. This is the case of Tricholoma frondosae and of Tricholoma chrysophyllum the first of which looks like the equestrian Tricholome and the second has slightly more olive hues.

Finally, it can be confused with the mortal Resplendent Cortinaria, Cortinarius splendens for which the most favorable living environment is under deciduous trees.

Living environment

This species generally uncommon, is a champignon mycorhizien pioneer of the unforested dune. It grows under forest cover, mostly under the pines with which it maintains a symbiosis myrcorhizienne.

Occasionally found under other conifers, it strongly appreciates the sandy soils of coastal forests. Growing most of the time in groups, its growth period is spread out from late summer to fall, before the first frosts appear.

Toxicity or culinary interest

This Tricholome was considered a very good edible before many serious or even fatal poisoning have been identified as the result of the consumption of this fungus. The first symptoms do not appear until 24 to 72 hours after ingestion but do not seem to cause digestive disorders. It is most often fatigue and muscle pain that occurs as a result of the breakdown of the muscular system. The effects are very random depending on the quantities consumed as well as the time elapsed between two tastings. It is so not recommended to taste the flavor of this species.

Uses

Not listed, although this species was formerly consumed.

Species and varieties of Tricholoma

Like the equestrian Tricholoma, some species of Tricholoma can be toxic:

  • Tricholoma bresadolanum : Bresadola’s tricholoma, greyish cap covered with gray-blackish streaks
  • Tricholoma josserandii : Josserand’s tricholoma, fatty and greyish cap
  • Tricholoma pardinum : Tabby tricholoma, greyish cap covered with a gray-brownish to gray-blackish wick
  • Tricholoma sciodes : Tricholome gray, greyish to slightly ochraceous with small streaks
  • Tricholoma virgatum : Stretched tricholoma, shiny hat, silvery gray
