Abstract Ravenelia breyniae SYDOW, parasitic on Melanthesa rhamnoides BLUME is autoecious, producing pycnia, uredinoid aecia, uredia, and telia. The teliospores differentiate by elongation of cells in the top stromatal layer while the central cuboid cells differentiate into a compound pedicel. The cell layer immediately below the maturing teliospore provides the cysts, one for each teliospore. Appendages on the surface of the teliospores differentiate from material of the apical wall.
