[Experience with homemade substrates for mycology].

The meaning of the words "home-made", "medium" and "soil" is defined. The formulae are given and the manner for preparing lactritmel, lacmel and tritmel is described. The same for horse and cow dung agar soils is done. The lactritmel (20 fold diluted in water) is recommended for the specific diagnosis of Candida albicans in its nascent culture. The first results are communicated, as obtained by slide culturing fungi on banana (Musa paradisiaca) fruit pulp without previous sterilization. The amusing aspect of fungi-culturing is emphasized.
