Mikrosyphar polysiphoniae is a small, endophytic brown alga in the order Ectocarpales that parasitizes red algae in the genus Polysiphonia. It penetrates into the cortical tissue of its host, forming small pustules visible on the host thallus surface. Assessed as Least Concern, it is found in temperate coastal marine environments in the Northern Hemisphere.

Mikrosyphar zosterae is a minute, parasitic brown alga in the family Ectocarpaceae, forming endophytic infections within the tissues of seagrasses, particularly Zostera species. It is assessed as Least Concern and is found in coastal marine habitats where seagrasses occur.
