The genus Osmoderma is a flagship taxon of invertebrate conservation in Europe and encompasses a complex of four accepted species. While species limits amongst Osmoderma have been…

Molecular analyses of soil and water commonly reveal large proportions of fungal taxa that cannot be assigned to any taxonomic or functional groups. Some of these so-called dark t…

Arbuscular mycorrhizal (AM) fungi - Glomeromycota and Endogonomycetes - comprise multiple species and higher-level taxa that have remained undescribed. We propose a mixed morpholo…
