J ohnson , T. W., J r . (Duke U., Durham, N. C.) Infection potential and growth of Lagenidium chthamalophilum. Amer. Jour. Bot. 47(5): 383—385. Illus. 1960.–Temperature and salinity influence infection of Chthamalus fragilis and Balanus amphitrite denticulata ova by Lagenidium chthamalophilum . Optimum conditions for infection are 20—22°C. in raw (as opposed to aged) sea water of 34 0/00 salinity. With increases in incubation temperature, the percentage of infection occurring in egg lamellae submerged in hypersaline waters also increases. Nutrition has essentially the same effect on salinity tolerance as water temperature: only on enriched agar media will L. chthamalophilum grow vegetatively at salinities well above that of normal sea water. Ova of B. amphitrite denticulata become infected by L. chthamalophilum only at a temperature of 15°C. in hypersaline water, or if the Balanus ova are subjected to below‐freezing temperatures before exposure to the fungus.
