Hesperomyces harmoniae, a new name for a common ectoparasitic fungus on the invasive alien ladybird Harmonia axyridis
Fungi in the order Laboulbeniales (Ascomycota, Laboulbeniomycetes) are obligate, microscopic ectoparasites of arthropods. These fungi, unlike their close relatives, never form hyphae. Instead, they produce a three-dimensional thallus that consists of several hundred to a thousand vegetative cells de...
