Dichomitus eucalypti is a crust fungus that was described as a new species in 1985 by Norwegian mycologist Leif Ryvarden.

Generative hyphae are thin walled with clamps, and measure 2.5–4  μm in diameter.

Found in the context, the binding hyphae are solid, hyaline, and measure 2–5 μm.

[1] The type was collected in George Gill Range (Northern Territory, Australia), where it was growing on river red gum (Eucalyptus camaldulensis).

At the time of its description, D. eucalypti was, in addition to D. epitephrus and D. leucoplacus, the third species of Dichomitus found in Australia.
