To index data on fungal parasites and saprotrophs on bog-rosemary (Andromeda polifolia) in raised peatlands in Western Siberia and in literature via Global Biotic Interactions (GloBI, https://globalbioticinteractions.org) . See more information in: Filippova, N., Thormann, M., others, 2015. The fungal consortium of Andromeda polifolia in bog habitats. Mires and Peat 16, 1. Abstract: (1) Andromeda polifolia (bog rosemary) is a common plant species in northern circumboreal peatlands. While not a major peat-forming species in most peatlands, it is characterised by a substantial woody below-ground biomass component that contributes directly to the accumulation of organic matter below the moss surface, as well as sclerophyllous leaf litter that contributes to the accumulation of organic matter above the moss surface. Rather little is known about the fungal communities associated with this plant species. Hence, we investigated the fungal consortium of A. polifolia in three distinct vegetation communities of ombrotrophic bogs near Khanty-Mansiysk, West Siberia, Russia, in 2012 and 2013. These vegetation communities were forested bog (Tr = treed), Sphagnum-dominated lawn (Ln), and Eriophorum-Sphagnum-dominated hummock (Er). (2) In total, 37 fungal taxa, belonging to five classes and 16 families, were identified and described morphologically. Seven fungal species were previously known from Andromeda as host. Others are reported for the first time, thus considerably expanding the fungal consortium of this dwarf shrub. Most taxa were saprobic on fallen leaves of A. polifolia found amongst Sphagnum in the bog. Two taxa were parasitic on living plant tissues and one taxon was saprobic on dead twigs. Three taxa, recorded only on A. polifolia leaves and on no other plant species or materials, may be host-specific to this dwarf shrub. (3) A quantitative analysis of the frequency of occurrence of all taxa showed that one taxon (Coccomyces duplicarioides) was very abundant, 64 % of the taxa occurred frequently, and 32 % of the ...
