Comestibilit\u00e9 discutable, un m\u00e9canisme de type allergique pourrait \u00eatre en cause pour les intoxications s\u00e9v\u00e8res. Les gens qui le consommaient nagu\u00e8re ne mangeaient que les exemplaires tr\u00e8s jeunes (trouv\u00e9s avec des exemplaires \u00e0 maturit\u00e9) afin de valider l’identification.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Remarque<\/p>\n<\/div><\/div>\n\n\n\n

Champignon tr\u00e8s commun, plut\u00f4t en fin de saison car il supporte bien les premi\u00e8res gel\u00e9es. Pour un clitocybe, il a une spor\u00e9e bien color\u00e9e (cr\u00e8me). Lorsqu’il est tout blanc (var. alba Bataille), il peut \u00eatre confondu avec Clitocybe robusta Peck \u00e0 spor\u00e9e plus claire, bien difficile \u00e0 distinguer. Clitocybe alexandri lui est plus m\u00e9ridionnal et vient sur calcaire. Autrefois consid\u00e9r\u00e9 comme comestible, il vaut mieux rejeter Clitocybe nebularis car il a \u00e9t\u00e9 responsable de nombreuses intoxications d’intensit\u00e9s variables, mais parfois avec un syndrome gastro-intestinal grave. Attention aux confusions avec l’Entolome livide aux lames \u00e9chancr\u00e9es, qui est toujours tr\u00e8s toxique.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

Syndrome associ\u00e9<\/p>\n<\/div><\/div>\n\n\n\n

Syndrome gastro-intestinal<\/strong> : 15 minutes \u00e0 2 heures apr\u00e8s l’ingestion. Se manifeste par des diarrh\u00e9es, douleurs abdominales parfois intenses. L’arr\u00eat des manifestations intervient spontan\u00e9ment en 2 jours au maximum, mais des intoxications nombreuses et sans gravit\u00e9 et quelques cas plus s\u00e9v\u00e8res ont \u00e9t\u00e9 document\u00e9s. Tr\u00e8s riche en mannitol, un glucide utilis\u00e9 en pharmacie pour traiter la constipation, il est naturellement laxatif. Plus les exemplaires seront \u00e2g\u00e9s plus ils seront riches en Mannitol, ce qui explique notamment les intoxications l\u00e9g\u00e8res. A ce jour, l’explication des intoxications plus s\u00e9v\u00e8res n’a pas \u00e9t\u00e9 document\u00e9e. Ce qui est certain c’est que les personnes chez qui il y a eu une intoxication s\u00e9v\u00e8re ne peuvent plus le consommer, l’odeur seule suffisant le plus souvent \u00e0 leur donner la naus\u00e9e.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

\n

Conduite \u00e0 tenir<\/p>\n<\/div><\/div>\n\n\n\n

Traitement symptomatique, \u00e9ventuellement hospitalisation. Au besoin, une r\u00e9hydratation hydro\u00e9lectrique par voie parent\u00e9rale peut \u00eatre mise en place.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n
