We study congruences involving truncated hypergeometric series of the form where p   is a prime and m,s$m,s$ are positive integers. These truncated hypergeometric series are related to the arithmetic of a family of K3 surfaces. For special values of λ  , with e2f4" title="Click to view the MathML source">s=1$s=1$, our congruences are stronger than those predicted by the theory of formal groups, because of the presence of elliptic curves with complex multiplications. They generalize a conjecture made by Stienstra and Beukers for the λ=1$\lambda =1$ case and confirm some other supercongruence conjectures at special values of λ.
