Table 2.
Results from DFAs indicating the number of basidiomata (N), Kaiser-Meyer-Olkin measure of sampling adequacy (KMO), Barlett’s test, Wilks’ lambda test, significance of chi-square statistic of Wilks’ lambda, percentage of correctly classified samples, Cohen’s kappa and significance of Z test (* means p < 0.001, ns means p > 0.001), and the six most discriminant variables selected for each group. AUS = G. austrominimum, CAL = G. calceum s.l., GRA = G. granulosum, MAR = G. marginatum, GLA = G. glaucescens, PAP = G. papinuttii, PAR = G. parvistriatum, MER = G. meridionale, PEC = G. pectinatum, PLI = G. plicatum, TEN = G. tenuipes.
