Yes, some parasites do eat algae.

Fungal Parasites and Algae

Some types of fungi, particularly those in the Chytridiomycota group, are known to parasitize and consume algae. These fungal parasites are common in freshwater systems.

  • Chytridiomycota: This group of fungi includes various species that act as parasites.
    • They prey on algae in freshwater environments.
    • Their host ranges can vary.

Host Range Examples

The host range for these parasites varies among species:

  • Narrow Host Range: Some parasites, like Paraphysoderma sedebokerensis, have very specific host targets.
  • Wide Host Range: Other parasites, such as Rhizophydium algavorum, can infect a wider variety of algae.
Parasite Species Host Range
Paraphysoderma sedebokerensis Narrow
Rhizophydium algavorum Wide

The reference states that members of the Chytridiomycota are extremely common fungal parasites in freshwater systems that prey on algae.
