The teleutospore is simple in Uromyces, Coleosporium, and Melampsora, it is two-celled in Gymnosporangium andPuccinia, it is built up of three to ten superposed cells in Phragmidium, andof a larger number in Xenodochus. In Triphragmidium it consists of threecells laterally placed and in Chrysomyxa and Cronartium the simple teleuto-spores are so massed together as to simulate compound forms: their realnature is revealed by their early separation one from another. One-celledteleutospores occur exceptionally in the two-celled species and are knownas mesospores. The teleutospores may be massed together and incrusted in the tissuesof the host, or they may be detached readily from their stalks and carriedby the wind or by other agencies. Further development may take place assoon as conditi
