The Episcopal church does not believe in transubstantiation; it believes in consubstantiation. That is the basis for why a RC cannot accept Communion at an Episcopal church.
Transubstantiation vs. mystery
The Episcopal Church does not believe in Transubstantiation, which is documented in the Book of Common Prayer, page 873 in the Articles of Religion. Transubstantiation is the belief that Jesus' physical body and blood are present in the Holy Communion elements. The bread and wine physically are transformed. The Episcopal Church believes Jesus is spiritually present in the the Holy Communion elements.
