Palmoclathrus is a monotypic genus of alga. The only species in the genus is Palmoclathrus stipitatus.[1]

Palmoclathrus is rare and has only been reported from the marine waters of southern Australia. It grows attached to rock surfaces at a depth of 7 to 60 m.[2]

The thalli of Palmoclathrus consist of dark green blades attached to a terete stipe that is 8 cm high and 5-10 mm in diameter. The blade has a peltate base that grows up to 2 cm long; the upper portion of the blade grows up to 15 cm, and is highly perforate (with many holes). The blade consists of a mucilaginous matrix with cells embedded in it; the cells are interspersed throughout the matrix, not connected to each other, forming a more dense layer underneath the blade surface. Cells are 8-10 μm in diameter and have one nucleus and a single cup-shaped chloroplast without pyrenoids. Eyespots and contractile vacuoles are lacking.[1][2]
