^aFor each pair of cocultivated isolates, the percentages of conidia and mycelia produced by each isolate were quantified on six agar media, each representing a different nutrient treatment; the coefficients of determination reflect the relationships of mycelial values to conidial values (n = 6) for each isolate pair.

^bThe coefficients of determination reflect the relationships of mycelial values to conidial values (n = 6) in each nutrient treatment. The asparagine treatments contained asparagine as the sole source of both carbon and nitrogen (0.1×, 15 mM asparagine; 1×, 150 mM asparagine). For Czapek's treatments, sucrose and nitrate were the carbon and nitrogen source, respectively (0.1× nitrate, 88 mM sucrose and 3.5 mM nitrate; 0.1× sucrose, 8.8 mM sucrose and 35 mM nitrate; 0.1× Czapek's agar, 8.8 mM sucrose and 3.5 mM nitrate; 1× Czapek's agar, 88 mM sucrose and 35 mM nitrate).
