A marked inhibiting effect against implanted sarcoma 180 was shown by the so far unknown glucan of a lichen, Gyrophora esculenta MIYOSHI. The glucan was isolated in a pure state and proved to be a partially acylated β-1, 6-glucan. The antitumour active component of another lichen, Lasallia papulosa (ACH.) LLANO, has been almost established to be identical with that of G. esculenta.
