Fungi and slime molds of alder and willow alluvial forests of the upper part of the Muránka river (central Slovakia)

Abstract

Mycological and floristic research was carried out in alluvial forests (alliances Alnion incanae Pawłowski in Pawłowski et al. 1928 and Salicion albae Soó 1930) in the alluvium of the Muránka river in the north-western part of the Gemer region in central Slovakia during 2009–2012. In the studied forest stands the authors identified altogether 236 macromycetes and 13 slime molds (in total 249 taxa). As the first records for Slovakia following specimens were found out: Diderma globosum var. europaeum, Fuligo laeviderma (Myxomycota), Entomophthora coleopterorum (Zygomycota), Acrospermum compressum, Belonopsis filispora, Echnoa infernalis, Xylaria digitata (Ascomycota) and Hohenbuehelia angustata, Melampsora amygdalinae (Basidiomycota). The highest number of taxa belong among lignicolous saprotrophes (158 species) and terrestric saprotrophes (51 species), this might be because of enough dead wood substrate and rich humus litter layer on alluvial soils in the habitats. On the other hand, the number of lignicolous parasites (13 taxa) and ectomycorrhizal symbionts (11 taxa) were rather low.
