n.a. means not applicable; n.s. means not significant.

¹ Significant p-values are shown in bold: experimental-wise error rate = 0.05.

² UNIFRAC [59,67].

³ Shared Chao-1 richness estimate for an OTU definition [44].

⁴ Jaccard index describing the dissimilarity between two communities.

⁵ Yue & Clayton measure of dissimilarity between the structures of two communities.

⁶ Two-sample Komogorov-Smirnov test with the null hypothesis that the allele distributions of the spores under comparison are the same.
