The layer of epidermis lying next the corium, into which the papillas of the skin project. It consists of several rows of cells, the deepest approximately columnar and perpendicular to the corium. The other cells are rounded or polyedral except those next the stratum corneum, which become flattened and parallel to the surface of the skin. The dark color of the skin is due to pigment granules in the r. mucosum, especially in the deepest layer, from which that layer is sometimes called the pigment layer. In the negro the entire r. mucosum is charged with pigment, and in most cases there is a limited amount of pigment in the cells of the stratum corneum. The cells of the r. mucosum are connected by fine proce es, and the layer next the corium is connected with corium in a similar way. [J, 30, 31, 35.] Cf. Pr/cfc/e-CELLs. R. tarseum (dorsale).
