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

Se consomme tr\u00e8s jeune, quand les tubes sont encore courts et la chair ferme. Plus vieux, le pied fibreux devient indigeste et la chair est trop molle. Sa chair s’oxydant \u00e0 l’air, il noircit \u00e0 la cuisson.
La nouvelle classification le consid\u00e8re comme synonyme de L. quercinum (Eyssartier et al., 2011). Dans l’ordre des Boletales, il existe des genres \u00e0 lames : Gomphidius, Paxillus, Omphalotus, Hygrophoropsis.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n
