Figure 2: Earliness (time period elapsed from substrate inoculation until the appearance of basidiomata primordia) for five mushroom species colonizing seven substrates in “race-tube” experiments. Values (days) from three strains per species were pooled and results are expressed as means ± standard errors of means, . Lack of letters in common indicates statistically significant differences (Gabriel’s -test, ) among substrates for each species examined.
