Plant diseases; Fungi. zu THE FUXGI WHICH CAUSE PLANT DISEASE The basidiospores are capable of infecting onlj- the appropriate alternate host and that when the parts are still j^oung and tender. An abnormal development of germ tubes instead of the usual promycelium has been reported in some instances. According to Lloj'd & Ridgwaj^ ^°' several crops of basidiospores are pro- duced in one season. The various species usually make good subjects with which to studj^ infection. The teliospore masses placed in water soon become covered with basidiospores.
