Identification
Yellow cap with a greenish tinge, sulfur-yellow gills, whitish-yellow stem. Grows under pines on sandy soils, late in the season.
What the clinic showed
Since 1992 France has recorded 12 cases of delayed rhabdomyolysis after meals rich in Tricholoma equestre. In Bedry et al. (N Engl J Med 2001) the link was considered clear: 1–3 days after eating came muscle weakness, pain and muscle-tissue breakdown threatening kidneys and heart. Some cases were severe; there were deaths. A later series (PMC5287993) confirms the picture.
In practice
- Not "the best fried mushroom" — repeated large portions are the documented risk pattern.
- Muscle pain, weakness and dark urine after a mushroom meal — hospital, with a mention of this species.
