Extension rates of selected wood-degrading fungi vary up to 7.5-fold with respect to substrate composition. We measured radial extension rates of three different sequenced wood-degrading fungi on five different substrates. P. chrysosporium had the greatest average extension rate followed by T. versicolor, and G. lucidum. Rates below 2 mm/day are shown but are considered to be at the limit of our measurement technique. Statistically significant differences were detected by way of Tukey’s HSD (p < 0.05) for P. chrysosporium and T. versicolor, and P. chrysosporium and G. lucidum. Statistically significant differences were detected by way of Tukey’s HSD (p < 0.05) for Compost and Wood Chip, Manure PDYA, and YSD; between Manure and PDYA; and between PDYA and Wood Chip. Radial extension rates for individual plates (points, n = 6 for all conditions except for T. versicolor on compost, n = 3), mean extension rates across all plates (bar height), and standard deviation across all plates (error bar) are shown
