Abstract: 3 fig. 10 tab. ["Aqueous solutions of the sodium salt of l-usnic acid (100ug/ml or less) inhibited growth and photosynthesis, rendered zoospores immotile, increased permeability, but did not affect pigment production in Trebouxia from Acarospora fuscata and Cladonia boryi. Respiration was inhibited in the former species but was stimulated in the latter."]
