A new species in the Liagoraceae (Nemaliales) having vegetative and male reproductive characteristics usually associated with the genus Helminthora is assigned to Helminthocladia (as Helminthocladia andersonii Searles & Lewis) on the basis of the shape of the conical carpogonial protoplast, three‐celled carpogonial filament, development of the carposporophyte from both cells formed by division of the zygote and development of the involucre without the formation of a bridge around the zygote or formation of rhizoids from the involucre. All of these are consistent characteristics of Helminthocladia and distinguish its species from those of Helminthora .
