Entoloma sinuatum
Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. E. sinuatum causes primarily gastrointestinal problems that, though not generally life-threatening, have been described as highly unpleasant.
About Entoloma sinuatum in brief
Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands. It has been responsible for many cases of mushroom poisoning in Europe. E. sinuatum causes primarily gastrointestinal problems that, though not generally life-threatening, have been described as highly unpleasant. Delirium and depression are uncommon sequelae. It is generally not considered to be lethal, although one source has reported deaths from the consumption of this mushroom. The saga of this species’ name begins in 1788 with the publication of part 8 of Jean Baptiste Bulliard’s Herbier de la France. In it was plate 382, representing a mushroom which he called Agaricus lividus. In 1872, Lucien Quélet took up a species which he. called “Entolomas lividUS Bull. But in 1950, a change in the International Code of Botanical Nomenclature caused only names on fungi published after 1801 or 1821 to be valid.
This meant that suddenly Bulliard’s name was no longer a valid name, and now it was Persoon’s name that had priority. Rolf Singer conceded the name was far more widely used and adopted it for his Agaricales in Modern Taxonomy text in 1986. In the meantime, it had been widely accepted that the 1950 change to the Stockholm Code caused more problems than they solved. In 1981, the Sydney Code reinstated the validity of pre-1801 names, but the status of those used in the foundational works of Persoon and Elias Fries had had to be re-examined about the same time. At the time, this made Quélet’s name unusable for this species. As a result, Henri Romagnesi, who studied the genus for over forty years, favoured RhodophyLLus. However, most other authorities have tended to favor Entolomas, and Singer conceded it was farMore widely used. In 1886, Magnus Fries created a sanctioned name for the species, which had been described by Quélet.
