  • a Growth versus no growth is shown as the fraction of 16 inoculation spots on SDAE plates for each dilution and condition after 9 days of incubation (plates had eight spots of 12 μl each). Dilutions with 103 and 102 fragments showed 11 of 80 spots for 35°C versus 3 of 80 at 30°C, or 1 of 80 at 25°C; P = 0.046 and 0.005, respectively, by Fisher's exact test.

  • b The initial inoculum contained approximately 107 hyphal fragments per ml.
