Scientific Name:Liagora valida Harv.
Description:Species Description - Extremely variable in size and habit, in the amount of calcification, in presence or absence of annulations, in the compactness of the cortex, in the subparallel or subumbellate disposition of the distal branches of the assimilatory filaments, and in the form and size of the peripheral cells, yet specific segregations seem to the writer to be impracticable. Plants growing on surf-beaten rocks between the tide-lines form rigid brittle closely adherent cushions suggesting fruticulose Lithothamnieae or species of the lichen genus Cladonia; those growing below the low-water line or in less agitated water are longer, laxer, less heavily calcified, and more flexible. In intermediate positions, forms of intermediate habit occur. Certain conditions of the species appear to be close to Liagora fragilis (Forsk. ?) Zanard. and L. rugosa Zanard., from the Bed Sea, with which they may need further comparisons.


On rocks from near the high-water mark, in exposed positions, down to a depth of at least one meter (low-tide).
