Ichthyosporea

The Ichthyosporea (or DRIP clade, or Mesomycetozoea) are a small group of Opisthokonta in Eukaryota (formerly protists), mostly parasites of fish and other animals.

Ichthyophonus is a genus of unicellular eukaryotic parasites of fish. They were once considered to be fungi, but phylogenetic evidence suggests they are protists related to both fungi and animals.
