A New Marine Phycomycete

Abstract

A marine fungus isolated from egg cases of Urosalpinx cinerea is described as Haliphthoros milfordensis, a new species and new genus which is made the type of a new family, the Haliphthoraceae, of filamentous holocarpic Saprolegniales. The Haliphthoraceae include as well the new genus Atkinsiella and Aphanomycopsis Scherffel. Synchaetophagus balticus is a nomen dubium. Haliphthoros milfordensis is obligately marine but euryhaline. This fungus grows well in a synthetic sea-water medium containing approximately equimolar concentrations of glucose (or soluble starch or glycerol) and NaH · glutamate (or Na · aspartate). Vitamins are not required.
