WebSpecies of Albugo (Table 1) are obligate parasites that can develop only in living host tissues. The fungi reproduce by asexual spores (spora ngia) and thick-walled sexual spores (oospores). The oospores and perennial mycelium in host tissu es enabl e these fungi to overseason in a few, systemically infected, living crop and weed hosts.
