Abstract

Interactions between fungi and tardigrades have scarcely been described. The few studies that address such relationships suggest a primarily parasitic nature for various fungal taxa, including the infectious chytridiomycetes. The aim of this study was to determine the identity of a fungus growing on a tardigrade of the genus Diaforobiotus and if it could infect other tardigrade genera. Using morphological analysis and ITS barcoding, we identified a mold isolate belonging to the Trichoderma harzianum species complex and found that it infected Diaforobiotus tardigrades, as well as animals in the eutardigrade genus Milnesium, and heterotardigrade genus Viridiscus.
