^aα_w: Water activities.

^bI_D: index of dominance according Magan and Lacey (1984).³⁶ Values were obtained by adding the values assigned to each species according to the interaction with the different water activities. Types of interaction and corresponding values: A - mutual intermingling (1), B - mutual antagonism on contact or with free space between fungus colonies <2 mm (2), C - mutual antagonism at a distance (3), D - dominance on contact (4 for the dominant species, 0 for the inhibited species), and E - dominance at a distance (5 for the dominant species, 0 for the inhibited species).

^cInteraction discarded because there was no growth.
