Aeciospores produced in nature on Ornithogalum umbellatum were used to inoculate barley plants growing in pots. In about 10 days after inoculation, uredia of Puccinia anomala were produced, and these were followed in mid-April by telia. The pycnia and aecia with their respective spores are described, as are the urediospores and teliospores produced as a result of the inoculations. Teliospores produced in April and remaining on host parts on the ground under natural conditions produced basidiospores the following November. The life cycle is completed by the transportation of basidiospores to nearby plants of Ornithogalum. Barley plantings are at that time well advanced,hence become exposed to aeciospore infection.
