The screening of 39 culinary and wild mushrooms showed remarkable results, especially the variability of the beta-glucan
contents in different species and the high levels of beta-glucans in species such as Boletus edulis (Bull. ex Fr., stipe part) or Piptoporus betulinus (Bull. ex Fr.) Karst. with more than 50 g/100 g dm. These result are in good accordance and support the work of , who screened several mushroom species with the Megazyme assay.
