Leathesia difformis, is a synonym for Leathesia marina (Lyngbye) Decaisne, 1842, commonly known as the sea cauliflower and the sea potato. It is a species of littoral brown algae in the class Phaeophyceae and the order Ectocarpales which is commonly attached to other seaweeds and sometimes rocks. When young, the organism is solid but as it matures it become hollow and somewhat convoluted and has the appearance of a small leathery brown bag about the same size as a tennis ball. The texture is rubbery and the outer surface smooth.^{[citation needed]}

These brain-like brown seaweeds can be found growing on rock or as epiphytes on other seaweeds in the mid to low intertidal. Individuals can grow to ~15 centimetres (5.9 in) in diameter. Young individuals can resemble other globular forms of algae, such as Soranthera ulvoidea.^[1]^[2] To determine if it is Leathesia, squeeze and flatten a piece between your fingers. Leathesia will break apart into filaments whereas other globular forms will flatten but remain intact.^[3]^[4]

Taxonomy

A 2011 study using phylogenetics found the following relationships between L. difformis and the rest of Chordariaceae.^[5]

Chordariaceae

Myrionema papilosum

	Myractula clandestina

	Elachista fucicola

Striaria attenuata

	Litosiphon laminariae

	Elachista flaccida

Elachista scutulata

	Punctaria latifolia

	Asperococcus bullosus

	Ulonema rhizophorum

	Myrionema strangulans

Ddictyosiphon foeniculaceus

	Chordaria flagelliformis

	Soranthera ulvoidea

	Corynophlaea crispa

	Leathesia difformis
