Phellinus linteus is a well-known species of the genus Phellinus, which attracts great attention due to its anti-tumor effect and other medicinal values.  The active polysaccharide, purified from mycelia culture of Phellinus linteus, stimulates humoral and cell-mediated immunity, and exhibits a wider range of immunostimulation and anti-tumor activity than other polysaccharides isolated from Basidiomycetes.
