1. Aqueous extracts and ethyl acetate extracts from the fruiting bodies and mycelia of various fungi were tested for anti-Candida albicans activity.
2. The aqueous extracts of the fruiting bodies of two mushrooms, Russula nigricans and Suillus placidus, elicited some inhibition of C albicans.
3. The ethyl acetate extracts of the fruiting bodies of all mushrooms did not produce a conspicuous inhibition of C albicans.
4. Accumulation of the nuclear dye SYTOX green in C albicans cells did not occur after exposure to the Russula nigricans and Suillus placidus aqueous extracts, suggesting that inhibition of C albicansis not due to a membrane permeabilising effect.
