Pair-wise comparison of fungal species richness in water-damaged and reference buildings pre- to post-remediation. Phylotype diversities (Sn) were calculated from clone library data separately for each sample and for each fungal class. The diversity ratio between the index and reference buildings (Sn(In):Sn(Re)) was calculated for each building pair pre- and post-remediation. The results for the two locations are shown separately. The species richness of Agaricomycetes, Eurotiomycetes and Dothideomycetes was higher in the index buildings in relation to reference buildings' pre-remediation, but decreased post-remediation.
