Blastocladia is a genus of aquatic fungi.

Description

Blastocladia species have a thallus that consists of a single, branched basal cell or trunk with rhizoids at one end and sporangia at the other. They are not able to use oxygen, although its presence does not inhibit growth.[1]

Habitat

Members of Blastocladia grow on submerged twigs and fruit.[1]

Taxonomy

Blastocladia was circumscribed by German scientist Paul Friedrich Reinsch in 1877, who included a single species, Blastocladia pringsheimii.[2] Roland Thaxter added a second species, B. ramosa in 1896. He placed the genus provisionally in the Pythiaceae owing to its resemblance of its resting spores to the conidia of some members of the genus Pythium.[3] Joseph Schröter (1897) included it with the water mold family Leptomitaceae.[4]
