Tricholoma equestre
Consumed during centuries and reserved for the palates but esquisitos, In Spain in ocubre of the 2006 has been prohibited the commercialization and consumption of these mushrooms. The reason is to have provoked RHABDOMYOLYSIS in some European countries, foods that included big quantities of this mushroom.

Tricholoma equestre or Tricholoma flavovirens, also known as Man on horseback or Yellow knight is a formerly widely eaten but hazardous fungus of the Tricholoma genus that forms ectomycorrhiza with pine trees.

Known as Grünling Pilz in German and canari in French, it has been treasured as an edible mushroom worldwide and is especially abundant in France. Although it is regarded as quite tasty, cases of poisoning from eating T. equestre have been reported. Research has revealed it to have poisonous properties.

Taxonomy and naming
Tricholoma equestre was known to Carolus Linnaeus who officially described it in Volume Two of his Species Plantarum in 1753, giving it the name Agaricus equestris,[1], predating a description of Agaricus flavovirens by Persoon in 1793. Thus this specific name meaning "of or pertaining to horses" in Latin takes precedence over Tricholoma flavovirens, the other scientific name by which this mushroom has been known. It was placed in the genus Tricholoma by German Paul Kummer his 1871 work Der Führer in die Pilzkunde.

The species may be in need of further analysis given the conflicting reports of toxicity.
Description
The stem is yellow, usually about 4 to 10 centimetres long with an even diameter. The gills are also yellow colour and the spores are white. The hat is usually a yellow to yellow-green sometimes with a touch of brown to brown-reddish colour. The diameter is usually from 5 to 12 centimetres in length. The skin layer covering the hat is sticky and can be peeled off.

It can easily be mistaken for a variety of other members of the Tricholoma genus, such as T. auratum, T. aestuans and T. sulphureum.

Toxicity
Long regarded as one of the tastier edible species, concern was first raised in southwestern France. People who have been poisoned have all had three or more meals containing T. equestre within the last two weeks prior to treatment. One to four days after their last meal containing the fungus, the patients reported weakness of the muscles, sometimes accompanied by pain. This weakness progressed for another three to four days accompanied by a feeling of stiffness and darkening of the urine. Periods of nausea, sweating, reddening of the face were also registered, but there were no fevers.

The still unknown poison in T. equestre accumulates in the muscles and can lead to rhabdomyolysis.

As yet, there have been no reported cases of poisoning in North America, and there is speculation that the respective mushrooms may in fact be different species that are very similar in appearance.

There are reports where patients treated for T. equestre poisoning have died, likely as a result of the poisoning

Buen ángulo y prespectiva que deja claro que que tipo de bosque es su preferido. Muy buena la información adicional. Por cierto, no la conocía...

Hola.
Me gusta el sujeto, pero el paisaje es un lujo.
Felicidades por el nuevo juguete, estoy seguro que le sacarás máximo partido soble todo a nivel del suelo ;)
Un saludo, Felipe.

Very good image of this dicey mushroom, Jose. You have done well to turn one of the pair up-side-down to show its salient features.
The perspective with trees in the BG also gives a good idea about their size.
TFS and regards.

Hola Jose Ramon,
Hermosa vista de estas setas, todo se ve muy bien a pesar del día nublado, me encanta también que se vea nítido en este caso el fondo arbolado. muy lindo trabajo

Saludos amigo, JL.

Hola José Ramon,
Fantastic composition, very good ideas. Spectacular colors, great sharpness, and I especially like the seeable background. Masterful image. Bravo.
Un saludo, László

Hi, Jose!
I am very surprised that these mushrooms are dangerous and poisonous! In Poland two species of Tricholoma mushrooms - Tricholoma equestre and Tricholoma portentosum belong to the most tasty mushrooms!! Every autumn I have them boiled, pickled and salted and although I am 63 years old I will eat them to the end of my life.
